currently working on fixing one for a friend. i had the same problem when taking it apart. sadly, it is the switch board that has failed this time, and i have no clue how to go about fixing it. any suggestions/ tips? I have double checked the cables are back in the right place, but none of the buttons work.
Start by using a multimeter to check that the connections from the switches to the socket are OK. Then connect the switch PCB to the cable and use the meter to check the connections at the far end of the cable. Logical fault-finding is the only way.
I hate the way modern TVs are made. Really cheap and nasty. And I hate the way they won't work without a signal. You don't know if the problem is the monitor or the signal really irritating!
Ah, Consumerism at it's worst (or best, depending on point of view). Its ridiculous really that components that are worth pennies end up consigning an otherwise perfectly fine monitor (or tv or washing machine or whatever) to the local tip, where I doubt very many are even recycled. Such a shame and really a complete waste of resources. Easy for those in the know to fix, but for many people (myself included), don't have the skills or equipment to hand to do it. Not to mention its quicker to stuff in the garage (where it sits for a few years before a clear out & a tip run) and go get a new one from Currys (other retailers are available etc). I'm not sure what the solution is though really, as they're clearly made to a price point and getting anyone with the skills to repair it would probably cost nearly as much as a new one anyway.
With 4k it's possible to read all the information off the front of your Santander VISA Debit card, along with presumably your bank account number below. I hope it's an old one. You might want to cancel it and get a new card as this information is public (or delete this video).
Thank you for the Video! Had the same Monitor dead and fixed before so here is what you want to change all Electrolytic caps after you have cracked it open with old creditcard that works much easier!! C203 470uF 35V C204 1000uF 16V C205 1000uF 16V C206 470uF 35V C212 1000uF 16V C301 470uF 35V C103 33uF 50V C105 0,22uF 50V
Thank you very much for this tutorial, just repaired mine. It were the capacitors . Changed the 1000 uF and the 470 uF. . Monitor was from Feb 2009 so has done well but can serve me a bit longer.now.
I'm afraid most people would chuck it away as they haven't got the skill to repair it like you and all the equipment unless like to go out to repair them for everybody?
I once had a monitor with blewn caps. The thing was still working, but the smell was terrible. I was like, easy job, just some new caps.... but I failed at opening the thing.
Smashing repair colin 😀 It's well worth the effort and some fresh capacitors, people throw far too much away thease days 😞 i've often found the stated lifetime of the capacitors is quite short. (Sabotage). I fixed a washing machine switchmode psu, all the caps were cooked and according to the data sheet the data showed the caps had roughly 18 months lifespan at full loading. That's exactly how long the machine worked for. I shoved panasonic low esr and high ripple capacitors in, perfect 😀.
Thanks for admitting that you don't have a clue how to read a datasheet :D The endurance rating (2000h etc) is *AT 105C* with full rated ripple current applied. Every 10C lower than that doubles the rated lifetime. I highly doubt that PSU ran at water-boiling temperatures 24/7
@@Knaeckebrotsaege Why thank you for slapping me ha ha :-D The original capacitors died at the 18 month period, the cap rating. Perhaps the original caps rating was crapper than spec :-D What matters is the panasonic low esr caps did the job. I tend to go overboard with parts spec anyway.
I have had many PSU capacitor failures on both Samsung & LG, it always seems to be the low voltage ones. These certainly were not meant to be repaired, as you have found, they are a sod to get into!
I did have a high voltage one fail in an Epson XP-55 printer a while back: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NKr7zPO7xIA.html So I do always check those too.
