How to fix Asus VG278 white screen 

Jeff, the fuse blown up was an 0603 smd ? thx for your help

I am envious of your ability to find and repair faults like this, with what appears to be no repair schematics. I aspire to learn to do this with my own stuff.

No bullshit...no 20 minutes explaining the issue...just a quick "This is what happens...this is the fix" in short order...Jeff, keep up the good work!

If Luis rossmann and Bob Ross had a baby it would be Jeff.

If the fuse was marked "O", then it was 2.5 amps.

Microsoft having issues?!? Say it ain't so!

Wow this has plagued so many people!

I am pretty good with a soldering iron, but the tiny SMD always give me trouble. Especially desoldering is tricky for me. Watching your videos motivates me to practice more :)

Not much help without demonstrating how to get the thing apart. That is ALWAYS the most difficult, tedious, mysterious part.

this manual work for Acer KG271 Cbmidpx ! gj man! too many people have same problem with Acer monitors and nobody answer! nobody only you! thank you so mutch! repair it under 1 euro LOL sorry for my bad english :)

i have same monitor i dont know someone to fix for me how m this fix cost is it worth to sell it for 40 USD OR should i try to fix it thank you

The day i got my IPC-7711 training at work, my screen has this issue. what are the chances... i guess i can put my soldering skills to the test

When he was checking fuse, did he say conti-nudity? Bahahahsha

i dont have the same package size as this one i only have this huge one . LMAO i spit my beer all over my keyboard. guess some guys just have all the luck with parts in the large package size lol

Well done :-D, A handy monitor saved from the dumpster of dooooom :-D Because so many fail, it makes me wonder if they selected an under rated mosfet on purpose. I would be trying to bodge a much bigger mosfet in there or near. I never liked the idea that transistors are supposed to be boiling, it's not a tube or valve. Don't forget to get the cat to do a final inspection :-D

Great job, It cant be fixed? Don't tell Jeff that.

Chalk another white screen fix courtesy of Jeff's video. Fuse was blown and Q308 was shorted Gate to Source. Replaced both components and the monitor is back to life! Much appreciated.

I have the same problem but on a similar model in the PG278QR I have a medium level of electronics but this type of equipment is the first time I have seen it, could you help me guide me and I have looked for the damage and I can't find it, it is an ASUS model!

Nicely done! A bit beyond my skill level of just replacing blown electrolytic caps.

Jeff you are the truth!! Avid follower of your channel!!

This video made me realize how stupid I am.. guess I'm not fixing my mine after all lol

Hi can you pls do ikon computer white screen 😢pls I have online class and I can’t do it cuz of white screen 😢

i think im just fucking dumb to not understand any of this

My monitor is not even a day old and got the fucking death screen

Thanks for the video. I had the same problem and had to replace q308 and q9(because it was literally melted) with a a09t. I also replaced the fuse at f001, but i am still getting a white screen. Im getting no continuity issues at the screen pcb. Any tips for what else could be the issue?

Mad skills! Well done sir!

whats your shipping address my monitor is still broken please fix

yeahh...ima just buy a new monitor..smh.

Continudity? :D

güzel video ama benim panel kartında başka sıkıntı var sigorta ve transistör sağlam 5v 3.3v girip çıkıyor

my monitor will come on eventuall,y but it's like starting a banger, the monitor will attempt to turn on then blink off but over time it warms up and then finally will stay on I am assuming it's some if not almost all the capacitors running on dead. which i assume should be easy to repair but this is an assumpton, the screen does go white but not always. it mainly shows asus logo for a split second then blacks out for 10 to 30 seconds. then trys again each time the logo will stay on a microsecond longer till it blinks for 2 seconds then shows a desktop then after 3 more blinks it stays on desktop . I have the HE version of this monitor need to know how to tear it down tho.

Nice repair.

thanks a ton , my friend ;) it works

God Bless you, Sir.

Picked a HP w19b from the trash, also showing same white screen which led me to this video. I went looking for a fuse around the same area of the t-con board and found a burned one too. There was no short to ground and I could not find any other problematic components in that board. I didn't have another fuse to try, so I did a solder bridge and got image on it. Put it back together early this morning and spent last hour and a half using it, so far so good.

Hi i have a Hp omen 27INCH QHD has rhe same proble can it fixed

Same components as LG GK750F. I've been searching for a technician that will do this soldering service, but it's just so hard where I live... All of them want to exchange the whole PCB, but LG doesn't provide 'parts', only the full panel for 75% of the monitor value.

Another great repair. Great job brother 👊🏼

Having a similar issue with an Asus 3d Vision that was second hand gifted to me. Turns on then rapidly whites out then turns off, back on, repeat Rather than go pay for a repair or replacement (since this thing is apparently like a couple hundred bucks to buy new), Would you know if I can fix it as well with the same steps?

Hi my HP 25x 144hz monitor got a similar problem but its not just white screen when you start mine was flickering and lines are appeared for 2 sec and goes back normal after 20 sec the screen turns white . if you know the problem please help me

I have that kind of monitor sir Asus VG278QR has a problem with diaplay black screen but if u put on lights display apps it can see but blurd i thinks background diaplay is the problem

Sir ..pls..help My monitor panel white then black... I can't find prob...

Thanks for sharing

I have the same problem with VP278 and i cant find the broken part...

SUPER!!

Tried it and didn't work! Replaced the fuse and Q308 and now the screen flashes white instead of solid white... Feels like an "almost" working. Tried my luck with Q303 as well and didn't affect the behaviour. Nice video! Really made it feel possible... for some. 😅

I have the same monitor, it has the same issue but kinda different. First I’ll be playing for hours, then when I switch something it turns white. Turn off monitor, then turn back on everything alright. Watching a video, games everything good. & turn white randomly. What can you tell me about that?

very good video , as usual , thank you

Cool fix

Thank you, James Donkey it worked on JD27GM144 model monitor (same motherboard)

your skills with monitors and tv's amazes me. You make them look easy... its not easy lol

Awesome video 👍

same problem bro My Monitor ASUS same issue with this

i have a acer xb271h that has a white screen but no blown fuse.

TV, Laptop or car, Best Practices work. What do I mean? Confirm the complaint, next do some simple checks while getting a lay of the circuit(s). Do a good visual as you may see the possible problem like signs or hot areas or discolored spots, replace the obvious but check to see if the problem is still there and confirm the part you removed is good or bad. This helps with confidence to move forward as you said, “Something made the fuse open”. Follow the circuit, simple quick test as the DMM on diode setting produces some voltage as diodes have a 0.7 volt drop. The mosfet is used as a switch & 95% are “N” channel type. If the numbers can be read, chances are you can find it or specs to help get a different brand. If in doubt, always go slightly bigger in amps, voltage or both. I miss the days the diagrams was on paper and under the back cover. At least many print it on the PC board. Nicely done.

the manufactory place doesnt wanna fix it they want u to pay for a new one

Can I just send u my tv n u can check out what’s wrong with it?

Dear Jeff Thanks for your generosity sharing your knowledge and experience with so many other folks like myself. God bless you! I have an ASUS VS24A with very similar problem - black screen, no logo, but when connected though a HDMI cable to a laptop, the computer recognizes the monitor, however no images are shown ASUS has suggested me to take it to an authorized shop but the cost was higher than a new monitor in Brazil. The problem started some 2 years ago when it went black and standby led was not turning on. I checked the power suply and replaced some inflated capacitors, a Mosfet 70Amps etc The standby light now turns on, backlight lamps are lit, etc but no images are formed I cheched the voltages goint to the ribbon cables tha connects to the monitor circuitry and the voltages there are 1.3xx Volts not 12V Without the schematicas (denied by ASUS) I have no clues as to what voltages should be supplied form the power supply board to the video card. There should be a 12V going through? Could you please offer some help? Thanks in advance and again congrats on the nice job

Mine did this. Am I supposed to do this myself 😂?

Hello, I sent you an e-mail, can you check?

Brilliant. Concise, no bullsh1t and no lengthy introduction. This is how to do tutorial videos. Thank you, will attempt this when I get the time and will let you know how I get on. Are there any old electronic items that I am likely to find the same transistor/fuse that I can rob? Perhaps from an old motherboard or laptop?

A

do u know how to fix a DISPLAYPORT HDMI DAMAGED 3IN BLACK LINE cause thats the problem that i have

I'd like to find the same one as the newly attached fuse. What can I find out?

thx

I have zero knowledge about this kind of stuff, but I refuse to pay Asus a couple hundred to fix their trash. What resources would you recommend for me to get started in aquiring this skill-set?

Can I send my monitor to u so u can fix it

Hey, I replaced the blown fuse on my and the transistor, but still a white screen. However, the fuse doesn't blow when I turn it on? Have I perhaps messed up something when soldering?

Great fix sir

I have the same exact problem is it possible to use a bigger transistor I have a couple I could take off of something but I don't know if I can use a different size transistor?

What kind of chip fuse do you use?

I have yellow dead pixel how to fix

This just happened to me and I am ill-equipped to fix it as he did, also my warranty has run out. Do I have any options?

Hi Jeff I have this issue but my Asus is pg278q and the board looks different. Would you happen to know how and where I can identify the spot for this little guy that I need to change?

Can you give some pointers to a noob (soldered on a few pcb for fun type of noob) for a project like this? Like where to start, required tools + equipments, skills needed (how to trace a short circuit) etc? much appreciated

Anyone know another substitute equvivalent of mosfet? I dont have the a03400 a09t in my country...

so sad :( got same issue but didnt fix mine i tested the fuse and its still working and the mosfet is also working but still in white screen :( can you please help me

I just swapped the parts and it still doesn’t work. I am on the verge of just tossing it away now. Must be numerous problems that could cause it. :(

Batteries for the Dyson V6 vacuum cleaner frequently have BMS board problems. If you could make a video fixing the BMS board at the component level it would be a big winner!

Awesome video. How did you figure out the Mosfet part number ?

Respect... I buy monitors from warranty providers with various issues and wish I had your skills... I fix many just by reseating connectors or cleaning... White screen is usually a no go for me... I've had a few Asus with no power and some with a wavy led back light mostly on whiter colors. Screen is fine just back light slightly pulses like a car lights with a bad alternator. Any ideas? Thanks

This literally just happened to my monitor of the exact same make/model. I'll be taking mine apart and diagnosing just as you did here. Thank you so much for this video. I just subscribed!

merhaba, arızalı parçayı bulmam için yardım ettin çok teşekkür ederim. :) benim monitör AOC G2790PX ve 16 haziranda beyaz ekran arızası verdi biraz elektronik bilgim ile kısa devre olduğunu anladım ve 5 adet kapasitör söktüm ama sorunu bulamadım. sonra senin vidyonu izledim aynı devre kartı olduğunu gördüm, 12H34 parçasını yerinden çıkardım ölçümde kısa devre olduğunu tespit ettim. lcd devresindeki kısa devre sorunu düzeldi. iki gün içerisinde AO3400 AO9T parça numaralı malzemeyi tedarik edip montajını yaptıktan sonra buradan sonucu yazarım.

*Great job like always!* Recently picked up TV that someone was giving away due to the half screen backlight was out. TV was used outside, therefore got some oxidation on the LED strips. Few solder points later I have a working TV with a free Netflix account (since the previous owner never logged out from the app :) ).

Do you offer repairs for these

Can you tell me what is on the Q9 position on the motherboard? Thank you!

Bro,what i can do when my monitor screen is white and menu isn’t working Only white screen

Can I grab the fuse and mosfet part from another monitor? Any old monitors use something similar?

Great job💪🏽

I cant do this alone fuk

I have a 27" Nixeus 240hz that has a white screen with only power connected. No start up logo. Is there a chance it could be the power supply? Or is it internal hardware damage for sure? If it's the latter I'm just going to scrap it since I got a few years out of it. If it could be a power supply then I'll replace it. The green light on the power brick shows solid green LED but I'm not sure if that's indicative of it working correctly. And it's the same price to buy a voltmeter as it is a new PSU.

The fuse you replaced, how many volts does it have?

How did you open up the monitor with out breaking the plastic

I got this problem and i wonder how should i fix it when im 15?

From where i can buy the parts ?

I have the same issue, where. I could get those replacement parts from locally in the US?

I replaced AO9T that it shorted.I replaced fuse that it shorted but the same.White screen... I cant find any short somewhere else.... Have you any idea ???🤔

Hi Jeff! Thanks for this video. I've started opening my monitor but sadly the problem seems different. My fuse "beeps" but the 3legged thingny is all shorted to grown. Is it possible that id only have to replace it? (i think you said it's called a moset.)

What are the specifications of the fuse that you used to replace the old fuse?

Great video. Working on the same monitor. I had to replace Q9 on the main board ( was incinerated, could not read p/n ) . C334, C338, C806 were shorted too on the screen's pcb. Removing C338 ( tiny black component , measures 0 ohm ) there was no more short on C344 and C806. Replacing Q308, F001 as you did , I get steady 12V on the screens's pcb, and these voltages : 1.24V on L302, 0.86v on L304, 3.3v on L305, 0.0V on L308, 0.09V on L307, 11.92V on L301. It is obvious not all voltages are correct , and there is still no picture , backlight only. If someone has more info , please comment.
