Re: vizio backlights but no video or audio
We need good clear pictures of the whole backside of the TV showing all the boards.

The Problem: This player has a toggle switch to select between Stereo, Mono R, and Mono L. Regardless of the setting it outputs the sound to both the L&R audio jacks. In the Mono R position, the audio output level is normal (from both the L and R audio output jacks), in the Stereo position the audio output is about half the volume, and in Mono L, it's about 3/4 the volume. Something about putting it into Stereo mode is causing the volume to drop significantly and I can't figure it out.

Have a free Vizio E60-E3 pickup - sound and backlights work. set turns on and stays on for a period then cycles off and back on. NO VIDEO. If I remove left side (from front of TV) of TCON cable - set has pic on right side (from front of TV) with white screen on left side. With right side TCON cable disconnected - no pic on either side.
Does this mean remove right side (from front of TV) tabs ?
Like a second opinion before possibly destroying set.... -

I disconnected one side of the T-Conn cable and got distorted video on one side of the Panel. I taped off a few pins on the T-Conn cable both side of the panel displays but distorted video. I also replaced the T-con board results same blank screen. Any suggestions?... -
'Morning,
I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.
Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.
I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.
I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate... -
Hi There,
This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.
After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.
