Folks,
Previous acts were reported in the following threads:
So now I'm in act 3 of my saga, trying to figure out if the replacement T-Con board is bad or not. I do have a (150 MHz) dual-trace scope (and access to fancier ones). Looks like the next step is tracing signals in and out of the T-Con board. Which leads to the following questions:
TIA,

Previous acts were reported in the following threads:
- Vizio VO42L, Backlite & PS OK, no pic, now what? https://www.badcaps.net/forum/showth...787#post259787 -- which led to tracing a bad supply voltage down to inside the T-Con board.
- Bad T-Con replacement board?
https://www.badcaps.net/forum/showthread.php?t=22413 -- After the T-Con board was replaced and all voltages were verified OK, I now get light on the screen, but no image (just solid white with a couple black bars)
So now I'm in act 3 of my saga, trying to figure out if the replacement T-Con board is bad or not. I do have a (150 MHz) dual-trace scope (and access to fancier ones). Looks like the next step is tracing signals in and out of the T-Con board. Which leads to the following questions:
- Is there any available tech info (general or specific) on expected signals in and out of a Philips 6870C-4200C T-Con board (question similar to a recent thread, https://www.badcaps.net/forum/showthread.php?t=22571)
- Curiously enough, I also have a 37" Vizio LCD TV of similar vintage. Haven't checked for T-Con similarity to the VO42L, but presume I could try comparing between the two. Advice?
TIA,
Mike
