I am wondering if someone has found the solution
Sounds like I have the identical problem.....
37AV502U No Picture, No Sound. Was watching a DVD via Component input when screen went black & loud garbled static came through speakers. I shut power down & turned on again.. no picture or sound.
Green LED Power indicator on, no sound & backlight does not appear to be on (viewed through rear of cabinet). Upon powering down there is a loud pop in speakers. I have noted this pop on & off the past few weeks on power down.
A few times in the last month the screen went black upon watching a DVD, Turning the set off then back on fixed the problem. I just take these glitches with a grain of salt as electronics is not as reliable & more prone to issues as it used to be. I am watching a 13" black & white in the meantime (circa 1979... bulletproof! I was very hesitant to go the route of these new flat screens, I don't think they have the bugs worked out & these sets are very frail & trouble prone.Edit: Set was purchased in June of '10 (old stock) had very light use in an ac & non smoking environment. The Hard reset per Toshiba is unplugging unit, hold power button in for about 15 seconds (I did it longer) releasing the power button then plug it back in (power is likely on, at least in my case). This did not return the set to normal for me per Toshiba it's more than likely a Main Board issue.
I like this set when it was working, & I have had pretty good luck with former Toshiba products, though I likely will not purchase a Toshiba on my next go around (if I even buy another TV).
Does the back panel release with just the screws or is there a trick to releasing it?) I would like to take a visual on this board to see if there was a latent solder issue (tin whisker or tombstone) that may had caused the failure
