Hi all. I have a Phillips TV, Serial NumberS8A1823101037, and Modal Number:50PFL5602/F7. My issue started out with flickering of only light colors on my screen. Now hdmi only has sound, no picture. Built in TV apps and TV menu appear as normal. For instance, I can see the built in youtube app. I click on it and it opens up youtube. But when I load the video, it's black . Not sure if it's the T-CON board or mainboard. The main board has a number stamped on it:BAB7R0G0201 1. I can find that. However there is a white sticker on it with the number:A7UMP10002564. I can not find a board with the same number as the sticker. Will a board with the number BAB7R0G0201 1 work, even though the white sticker numbers do not match? I know this is wordy, but hope it's understandable. Thanks for any input or help.
