Re: UE40D5000 red led blinking (PSU, Main board and T-con changed)
If it is the BGA solder on the main board's CPU, you could try heating the CPU to melt/reflow the solder as a workaround. It is not a guaranteed fix and there is a good chance the problem will show up again at a later date, but it is low or no cost option and may get you a few more months or more of use from the set without having to replace the whole board.

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
I have a Sony 65A8H. Always bothered me that it doesn't have HDMI 2.1. I noticed the A80J board appears quite similar. And comparing some wiring diagrams in the service manuals (albeit A9G vs A90J since I couldn't find the A8/80 manuals), things appeared quite similar. And my understanding is the panels between the two TVs are more or less the same.
So I decided I'd experiment a little bit.
I bought an A80J board. Left the speaker connection unplugged because it doesn't fit. Changed the power connector to fit the new board. Plugged in everything else.

Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side... -
I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
Obviously the same LVDS connector for the screen connection... -
My Oled Tv is 55inch tv, 3 days ago I notice that middle of the screen is getting warmer and on picture I have ghosting, missing red color. Color red was still displaying, but it was not so strong as corners of the screen and watching some movies makes me angry.
Then I get an idea to take it apart and clean boards from dust.
In side of Tv was not so bad, I take compressed air in can, and gently blow up.
Also I was thinking to styrofoam sponge to isolate power board from screen that the middle of the screen will not worm so much. Because Led on screen when gets higher...
