Hello,
Samsung plasma PN64E550 made some popping noises when turning on, the audio still works but there is no image on the TV. I have checked the screen for cracks with a flashlight and did not notice any (are cracked panels fairly noticeable?) There is no light at all on the screen, even in a dark room and visually I didn't see any burnt/bulging caps or chips.
I've tested for voltage here and there based on other threads i found and couldn't really pinpoint the problem. Also tried the fast track manual on toms service guides with no luck. And after reading through what seems to be like 100 pages of troubleshooting on forums and what not i'm pretty confused on the correct way to trace out and identify the failed board. I ended up buying and replacing the x and y main boards but still no image on the TV. What else can i check or test at this point? I have an electrical background so testing for correct voltage here and there would be no problem if i had some guidance on what to test. Any advice would be greatly appreciated!!
X board: LJ92-01788B
Y board: LJ92-01789B
Both these parts matched my originals as well as the rev number. Bought off ebay from a tv repair company, who says they were tested in a working tv set.
