well that's quite a bit different than "I get nothing with either side disconnected." You would be wise to post some pictures of what you are actually seeing with various cable disconnect scenarios to remove any "misunderstanding". Ensure that you are feeding a good signal along with also trying different menu screens to see show as much about what is happening on the screen. My guess would be an SMD capacitor on the bottom edge board might be bad.... but that's going on very little. Where did you get your tcon from? what's history on the set that caused the first post (ie. solarization).

That is how I received the TV in the first photo no history report before that. I was measuring the voltages on the t-con board when the TV got vertical lines across it not sure what I done for that to have happened. With new t-con board (purchased from an eBay seller) the lines still persist in the same way as the old one. Pressing menu on the remote or anything has no affect the lines are in a solid state and do not move or change colors when pressing anything on the remote control. I couldn't get a picture with my ribbon cable only plugged into the right side of the panel one side of the screen is literally just a shade or 2 brighter and my camera can't even pick it up. I'll check out the caps and see if I find anything for now.

I may pick up a 55LW6500 that doesn't power on just in case mine is beyond my ability to repair. I believe that model has identical parts.

Don't want to leave this thread on a cliff hanger.... I was unable to find any bad caps on the panel PCB's. Guess somewhere I really messed up and destroyed the panel somehow. I let that other TV slip away from me but will keep my parts and maybe come across another same model TV so I can get one working. Until then thank you all for your generosity of helping me out!

Those lines look like the cables are not seated properly. Are the ribbons "offset" slightly from the tcon connectors by chance ?

Thanks for the reply I've re-seated them several times they seem to look as if they are aligned properly. Maybe I could have damaged one by mistake?

I found another 55LW5600 model TV and bought it for $60. Stand by came on but no backlights or picture. I threw the mainboard from the other TV in it and got backlights, sound, and solarized picture just as the first TV was doing.
