Hi, can you expand on what you did? Did you really bake the board in the oven? If so, for how long and at what temperature? Is it still working?

[@tcong9616]

@@nathaniel781 I did really bake the board in the oven as prescribed. The baking time was about 10 minutes at about 250 degrees (can't recall specifically) and kept an eye on it to avoid "melting the board". Regretfully, after a few months of returned operation, the black screen returned and I ended up just replacing the ten year old TV.

Hello good video. My tv there is no signal from HDMI ports. The first time I had no signal I removed the power cable and reconnected it back and it came back to normal. After that I had the same problem again and several times over and over now I can only use AVI connection. I was checking the msd capacitors around the IC and I found 4 bad ones but I am not sure if I was testing the capacitors right. Do you normally check those capacitors around the IC?.

Thanks for the heads up. I've been doing research for a HDMI signal problem on Mistubishi 65 inch dlp. It loses the signal and I have to exit and reselect HDMI input. After signal loss sometimes the HDMI input is not visible when attempting to reselect, only AV selection is shows on screen. You need to make repeated attempts before HDMI shows on screen.

Hi Paul, My LG TV from 2010 seems to have the same issue for almost 3 months, what I tried: - I have used a hair heater to identify from where the problem come from: 5 minutes on the chip and the TV comme back to life for 7 days And the solution is temporary like you said because the issue have reoccured. - So I tried your solution and I resoldered the IC like your video but nothing happens. So I tried to reheat the IC with the hair heater and it worked like a charm. I have tried to resolder maybe 4 times the IC with good purchases and aterials but it seems that only the reheat of the chip make the IC reworking. Do you have an idea or something else?

Your thoughts: I have a 75' (new) HDMI cable that when I test it on four different TV's it works perfectly.

The HDMI source is coming from a security system through a powered HDMI splitter. I'm at a loss.

[@RSChris666]

Could be signal loss with the Panasonic TV. HDMI cables at that length tend to start getting iffy about signal strength. You really want to keep HDMI cable's as short as possible to avoid this issue. Or convert to SDI cable, but the requires multiple converters and cable and can get expensive.

I am having fairly good knowledge of electronics as a technical person in maintenance of communication equipments, and little knowledge about TV. I appreciate your help in solving the problem.
