    RCA LED60B55R120Q No OSD, No Video

    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
      Willing to help but I'm no expert.

                  P15 Gen 1 (type 20ST, 20SU) Laptop (ThinkPad) - Type 20ST need main and video BIOS

                  P15 Gen 1 (type 20ST, 20SU) Laptop (ThinkPad) - Type 20ST needs the main BIOS and video. The client says that after the Windows updates there was a firmware update and after that the device makes the sound of music when there is no screen. Moreover, if you turn it on several times then the picture sometimes appears and it works and passes all tests (wonder)
                  and may even reboot normally a couple of times
                  Now he doesn't want it anymore, no matter what I tried
                  It helped to change the video cable a couple of times, I ordered a new cable, it didn't help
                  Of course I checked the...

                  Samsung UE65RU7090UXZT main board issue no video out. BN94-14180M
                  by alltvrepairs
                  Hi,

                  I have confirmed that I have a mainboard problem.
                  I have tracked no hardware issued on board so might be a software dump required.

                  I have searched a bit but wasn't able to find anything for my screen:

                  Here are some more details:
                  Panel: cy-nn065hgev1h
                  Main: BN94-14180M P08F

                  Your help much appreciated!

                  ​

                  Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...
