RCA LED60B55R120Q No OSD, No Video

[taft1957]

Its a beautiful tv, No Power to start. Jumped 5 vollts to power on. Backlight came one. So I replaced the main board. Set turns on now with remote, and main power. However, no OSD, no video, no audio. Did the flashlight test, no data showing at all. Is this a TCON problem, FRC board, or main LCD panel?

Thanks

So you have backlights and can control the power on / off using the remote.

Can you post pictures of the circuit boards and of the labels giving the functions of the connectors, eg. STBY5V, GND......etc
