FINALLY! Ultimate Guide to Troubleshooting any Sony LED TV with a blink code. KD-60X690E 6 Blinks. 

Great video BigDog. bBacklight led's replaced but getting sound and no video. Connectors are all good. Thank you!!

At 23:30 is where you missed the clue: The B+ was running at 160+ volts. You read 63 volts on the return (B-) you should have been reading almost ground or about .7 volts above ground on B-. You read 63 volts since each diode has a forward drop even in an open circuit which is what you had. The B- is typically pulled down via transistor or FET and the B+ then adjusted to reach the proper current. Some TVs pulse width modulate the B+ to achieve this - some feeedback bias the base on the B+ power. But in you case you should have been reading about .7 volts above ground on the B- instead it was floating to the B+ minus all the forward LED drops. Nevertheless this was an awesome breakdown and THANK YOU. Subscribed!!!

Sony & Panasonic have been beacons in the electronics industry for decades.

I fixed the issue following your video. very helpful and your video is very detailed. thanks for the detailed video...

Thanks Marc just goes to show not always backlights

What multimeter is that? I liked it. Greetings from Mexico

That set has one big series string led circuit and when one goes out all goes out. The led tester supplies a much higher voltage but limited current that temporarily arc welds a carbon track across any open junction and creates a temporary complete circuit that won't last. I do this with my old sencore capacitor leakage tester it can supply from 3 to 600 volts leakage test voltage😁. Very good trouble shooting big man👍. I'm an old TV repairman that managed to survive. Now if I can get SONY replacement main boards to accept their software. I have an account with SONY and I get the software from the right place but some main boards will not accept the software no matter what I do grrr. I wish they supply boards with software already in because if you have for example a bad panel or T-con it can possibly prevent software from going in the new main board and you can't tell if its the new board or if you have two problems along with a bad main board. Sometimes it goes in sometimes not then you have to go into the service mode and transfer the data from the T-con to the new main board. I hate SONY. They're the best PERFORMING TV but a pain in the butt for a repairman. Their warranty service policies suck and REQUIRE too much from an underpaid repair tech and they don't pay enough money for what they require me to do. I can do what they want but its too much.I hope they go out of business soon If they do I will celebrate

Isn a much easier and simpler way to check led's without any voltmeter or led tester is to place tv down safely on screen, remove cover, plug in and turn tv on, look for steel case vent holes and see if led's are on. If lights are bright, it's not led strips, if off amd code blinking 6 times then you can assume it needs led's . Then check supply voltage at led supply and see if led's come on if they do, then check voltage at power board. If no voltage at power board then you got a burnt power supply. I do agree you should also be connecting voltmeter in series at led pig tail connector, and voltage at led's. Always double check because you could potentially have multiple failures

Hi great video and good info. but my question is have you done a Sony with back light LD board which has more LED wires than just 2 wires for the entire tv? I have a Sony 65X950G got Sony and android logo but then 4 blink red. I just want to confirm it is not any other boards other than the LED before taking it apart. any way to confirm or double check if it is the mainboard or LED board. I don't think the power supply board is the issue as I get all the 3.3v and 12v and I press power I get the Tcon 12v thanks

Thank you Guru. Very helpful information

Awesome! I love this complete process of elimination

Thanks very much for sharing your knowledge!! 👍

Good work 👍

Hi thanks for the video. I replaced my power supply on the kd60x690e 6 months ago and it worked great and then seems to have fried again. I have another power supply board to install and was wondering if maybe I did something wrong when I originally replaced it. Is there any tips to avoid this or is it just poor quality parts?

my same model tv has 6 red light flash ,but able to turn it non, after power on, the tv cooler went blueish , did not happened before, the usual colour is normal, is it backlight problem as well ?

I've had mine since September of 2018. Only issue is that sometimes it won't display a picture when I turn it on with the Sync up with my PS5. Easy solution is to turn the TV off either by the remote or by unplugging it and plug it back in. As when I say it won't display is that it turns and the screen is on but no picture and I'm not able to use the remote sometimes which is why I unplug it. I'm not gonna get rid of it unless need be but for now I'm keeping it. I honestly don't care about tech that much but it was the size and features like 4K, UltraHDR and Smart LED which this TV has. The only issue I have is that you can't find it anywhere because of that planned obsolescence of retailers and online shopping. Let alone I've tried before even on RU-vid to even find more about it while looking for the best picture quality for gaming and whatever else. Which I believe I have had gotten by different videos using a different Sony TV and I haven't touched it besides getting the right amount of color and brightness out.

Where do u reside at I have the same problem with my sony TV if u close I would like to fix it for me I live in Troy Alabama

thanks so much for sharing. i have an old kld-55nx720, once plug to power it has two steady red and amber standby lights. no blinks, nothing else works. do you have any possible ideal what the problem could be?

Thanks man, so i have to change the power supply board? I've actually had to change the backlights cause they haven't been working, so I've changed them, but the TV doesn't works and keeps the 6 blinks.

Big dog, I have A Sony XBR75 X 910C, I have the 4 blink error code. What is the cost to replace LED strips considering I can find new replacements? This TV has great picture and 3D so I believe repairing is worth it. Thanks much Andy

Great Video as always - thanks! I have a similar Sony model KD49X7000D which does not have the blinking red light issue but has developed very noticeable purple blotches over sections of the screen. These seem to have spread over the past 18 months. The screen itself turns on fine. I think the actual LED strips need replacing. Does that sound like I'm on the right track? Thanks again.

I'd like to know why on the boot up I'm not allowed to select TV but all the other stuff like HDMI and mirroring shows

bigdog whats brand is your digital multimeter ? looks dope, where can I buy one..

KD-55XD8005 Dublin Ireland. Just this morning I got the 6 blinking red lights on the set. What do you think people fix or dump it’s only 6 years old

Do you have spare parts for this exact tv? I think I damaged the MB to TCON ribbon cable.

Mine is KDL 50W800B 50" 3D, 6 time red light blinking, will this solution work on my model?

Good Job

mine is having the 3 flash issue. when set is turned on, you can here the relay engage. Then shortly after it shuts off.

If it’s blink 6 times then it’s backlight. Fixed 3 Sony tv had same issues

After my attempts to find a solution. This one had a sneaky little problem with the wires that connects to the led. They are pulled so tight that connections become lose.

How do I treat for 4times blinking issue? Thanks

heollo again BigDog, ive already changed the backlights and the power source board, but i have the bl error oscilate about 3.1 and 3.2, what can i do, this tv pissed me off, im going crazy, thanks btw

Man I'll never buyin a sony TV ever again..my x900h went 4 blinks AFTER 2 YEARS!! while my 2017 4K LG still strong..wtf is going with these Sony TVs? I spent $2K just for the TV to die almost 3 yrs later..mines turn on but it shut down after like 10 seconds..I take care of all my TVs.. LGs are the Kings

I have a smaller version of the Sony TV with the stupid six blink error.

I have a KDL-52VE5 that the power Led shows green, then shortly after the red Led starts blinking 6 times. Do you have a video just for this TV? Go Pack go! Don't be a hater. LOL

Hello sir can you provide the main motherboard of Sony KD-70X6700E

Someone know what about 2 blinking red light?

XBR 85X850F , TV turns on with the backlights , then 5 red blinks and it turns off , any ideas ?

You da man!!!

Dope vid !

Nice troubleshooting big dog led tvs sure don’t last as long as lcd tv did that’s why I tell people don’t spend a lot of money on a tv because ur lucky to get 4 to 5 yrs on one.

Me: watching video on 50 inch, 15 year old, flawless running Insignia with countless hours on it from all night gaming and movie marathons, on how to repair a 3 year old 80 inch sony bravia xbr tv "sony is the best" mmmkay : /

Go Bears!

Sony is crap, they are famous for their disabling software on their tv’s. Even though there is an issue the tv can still function albeit with maybe a dimmer picture, dark area or android software issue or voltage drop on power but Sony makes sure the TV locks up to blank screen, rendering it useless intentionally until serviced or new tv purchased. My 2nd Bravia lasted only 2 1/2 years and the first only 3. My old LGs, both are going strong at over 8 years. Never buy Sony TV they scam you. Can you imagine if a vehicle manufacturer did this? Car disables itself if the tail lights go out or the AC cut out? The BL_err bypass hack on the TV’s prove they can still function.

Again!

This absolutely did NOT help me with trouble shooting. This was a tutorial on checking voltages between boards.. #Tapology Such a waste of my time

NOPE! Sony is CRAP! Samsung & Vizio are best...

I have Sony Bravia XBR 55X800E. When turned on. Sony logo come On, then it tried to load the int turns off. Then, it gives me 6 red blinking lights. Any idea? Please help
