"More update. If I unplug one of four connectors that go to lcd panel, turn on TV, turn TV off, and then plug that connector back, and turn on TV, then the picture is almost 100% good. Maybe some problem with power supply on T-con board?"
That is aout the same symptom as the LG I worked on.

I changed the capacitors in the power supply, just in case, but it's still the same. I can get it working if I turn on and off the TV, until the picture is ok. But when I turn it off, the picture is bad again. Any more ideas?

If I buy a new T-con board, which one is compatible? This?

The part number "FRCM_TCON_V0.1" must be the same and the t-con must have the same connectors/connections.
