SAMSUNG UE55D6507 - vertical bars / lines

[olegeisler]

Another freebie I got SAMSUNG UE55D6507 chassis U69A, but this one also looks like it will have to go the scrapyard, unless some of you clever people can give me a hint with some magic

(I dont have the remote control for this one)

Symptom : Vertical lines/bars at bootup, see attached picture
All voltages from power supply OK
Backlight OK

My guess : Bad mainboard....

I will be happy to be corrected

Service manual + chassis pictures + screen picture attached

Clean and re-seat all cables and connectors at both ends of each to and from the T-CON Bd. Yes it could be a Main Bd. issue or it could be a T-CON Bd issue, also. Not ruling out the Panel, as a last option mind you. Do you have an Oscilloscope??

Yes, I have an oscilloscope, I have all kind of instruments, and knowledge how to use them. So any directions saying I should check something - I am fully able.

Do as I suggested in Post #2. Then we could test the LVDS to see if we have signals from the Main Bd.

Did you inspect the connectors?
This may or may not be applied to your model but it is worth inspecting.

Hello

I had the same problem on a samsung UE48C6700.

I solved it by pressing one of the motherboard chipset with an inner tube wedged between the chipset and the TV cover.

Try on all the bga on the motherboard, mine works very well for 2 years now .

In my house it worked.
