Re: Vizio VP50 HDTV20A - Sound, but no picture

Thanks TW2005 -

Any idea how I would go about testing that Y-main? Image attached for reference......

Hi all - I've been searching around the existing topics for this TV, and I've made some headway, but am now unsure how to proceed.

I'm working on a VP50 HDTV20A with all Samsung parts. Basically the TV has sound, but no picture on any input. Not even a backlight on the screen.

After removing the upper y buffer, I have backlight and sound on the lower half of the screen, but no picture. If I remove just the lower y buffer, there is no change from the original problem.

Should I just replace the upper y buffer and call it a day? Or will that not fix...

Hi all - my name is Steve and I'm just starting to get into TV repair. Really need some help with an issue and this seems like the best site to ask for it.
