TV has no picture but is back light and has sound.
Boards
T-Con HV55WU2- 370
Main 3655-0822-0395(3B)
Measurements
All measured Main board test points check out.
All measured T-Con board test points check out ONLY when left panel ribbon cable is disconnected. If the cable is connected, most of the voltages around the ribbon cable/lower right/left IC drop to 0v ( as if something is shorting )
Cannot find any shorts to ground anywhere on T-Con and on left side Panel PCB
Observations
When the left side panel ribbon cable is disconnected and TV is powered, a picture can be seen on the right side of the TV while the left is completely white. When the ribbon cable is connected, then the entire panel is black ( with backlight)
Replacing the T-Con board did not resolve the issue.
Questions
At this point I am confident that this is a bad panel but wouldn't there be some sort of evidence such as a short ? I measured all the components on the panel PCB and they all seem ok, nor was I able to find any shorts.
Before I rip this TV apart for parts thought I first check in with you guys for any suggestions/
