Hello everyone. I randomly came across this forum while trying to pin point the fix for the issue that i'm having. From what i've read so far there appear to be many knowledgeable people on here who know there stuff so hopefully i can leverage your awesomeness to fix my woes.
TV Model : HPS5053X/XAA
This TV came with the house that I recently bought. Didn't realize it had flaws so I was pretty stoked about it. It is mounted to the wall about 6 feet in the air, so getting it down isnt easy for me. I plan on getting a buddy over to help me take it down while i trouble shoot and fix it (over the course of a few weeks i'm assuming).
I've had someone out already. We got it down off the wall and he took the back off. I remember him tapping the top of the big capacitors and saying that none of them appear to be blown, etc. I cant remember which board he said it was, but he couldnt guarantee that replacing the one board would fix the issue or that another board wouldnt fry in the near future.
My symptoms are the colored pixel snow all over the screen. they dont appear on dark blacks (like the screen that shows when no input is detected) ... they appear pretty much all over the screen, more dominantly in the the middle than on the edges ... they appear to be red and green specifically but i remember the guy saying it looked more like all colors. To me it looks as though its just red and green sparkles all over the screen.
At any rate, from all the research i've done it appears that the Y SUS, LOGIC board(which may be the same thing as the Y sus??), or the Power supply board.
I originally thought that my only problem was that the pentimeters(sp?) needed to be adjusted. the tv guy said that wouldnt fix it, but i made him mess with them anyway. The sparkles did appear to be get better, but they never fully went away. The TV is still watchable for sure, but i can see these sparkles and it drives me nuts. I also notice ghosting sometimes on certain scenes but i'm not sure if thats related or not. Its like the characters on TV have tracer shadows .. that doesnt happen all the time though.
I've read that if i replace one board i might need to replace them all. I've read that you need to replace the buffers of the x or y boards at the same time or else ... i've also read that if you do happen to get the right board replaced that you'll most likely have to readjust the voltages after installation and after it gets a few months (also read a few hours) of use to ensure the voltage stays the same.
I'm on a budget for sure but i figure if i replace a couple of boards over the course of a month or so for less than 300 bucks i'm doing pretty good. Hoping to get some good advice here on where to start and how to test a few things to ensure i'm going in the right direction.
I'm no electrical engineer by any means, but i like to think i'm capable of this type of thing. i'm less likely going to attempt to replace individual capacitors, but i'm fine with the board swaps. I'm more than comfortable working on cars, computers, houses etc. Replacing the board in the TV should be a simple affair and i'm not scared to measure resistance/voltage with my voltmeter either.
I AM terrified of the stored voltage in the TV though. any tips on that would be greatly appreciated as well. I know i can just let the tv sit for a while to let it all drain out, but i'm not sure of the amount of time that requires.
here are the videos showing the symptoms

Once the camera adjusts to the light, you can see the sparkles here.

In this one i'm trying to show that the sparkles dont show up in the black, but do in the blue menu boxes. When i show the black it appears kinda weird, but that's the just the camera. You should be able to see the sparkle in the blue towards the end.
also an external link to another site that i'm sure some of you have seen that shows exactly what my symptoms are like and what i've already done (adjust the screw voltages)

I know this is a huge post and very long, but i'm just trying to be as complete as i can. I'm going to take the TV down in about two weeks (the wall behind the tv was never painted and looks horrible. We have a party coming up so i'm waiting till its over before taking down the tv) I can post pictures of the boards, etc at that time. I'm hoping to have a replacement board received already by the time i take the TV down if possible based on my symptoms evidence above ...
Thanks!!!
