    LG 60px950-UA no remote reception after main board replaced

    Hello,

    This TV originally had the common symptom of shutdown after brief flash of raster and I replaced the main board EBR71767001 (subbed to a EBT61259501) which repaired the problem, but now I have NO REMOTE RECEPTION.

    I could not find any loose plugs or cables and everything seems fine.

    I thought it might need a firmware update, but I cannot select that option in the TV menu without a remote control.

    I have tested the IR board and found that I can see AC voltage on one of the pins of the IR receiver rising whenever a remote is discharged into the IR receiver, so it seems that the problem is not there.

    Can anyone help me to see if my main board is defective or where the problem may be?

    Thanks!

      Is it okay to bump this thread up to the top?

          I would guess it needs a different remote.

          A working TV? How boring!

              Well, tried three different verified remotes...so...I would surmise that's NOT the issue.

                  Is it exactly the same mainboard....?

                  If not, you could try one of those 'universal' remotes and try some different codes to see if that helps out....

                      It is from one of my LG distributors and is a sub, but looks visually identical. They say it is the correct sub part for the original part number. I am having them do some research to confirm that it is a correct sub.

                      I guess it's possible that a different IR frequency might work than the LG one that it's supposed to work on, but I don't know. I will wait and see what the research returns and report back.

                          Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
                          by cheeky2
                          I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
                          Obviously the same LVDS connector for the screen connection...

                          Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                          by Asraf Atb
                          Hi everyone,

                          Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                          Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                          I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                          M60-C3 Replaced PSU & Main Board: Still No Good
                          by yoyokafka
                          My tv only goes to the splash/logo screen then turns off and repeats this on its own every couple minutes. I replaced the main board and got the same thing. So I replaced the power board and still got the same thing.

                          Could it be the T-Con? The logo screen indicates it's processing the image and outputting to the screen and triggering the LEDs just fine. But could there be something with the communication between the T-Con & the main board that prevents the main board from continuing it's bootup into it's operating system?

                          Someone please help me figure out what...

                          Sony xbr-65x900c main board issues?
                          by jb_Bak
                          Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

                          Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
                          Power Board Connector that goes to Main board
                          CN6401
                          Pin 01 NC
                          Pin 02 NC
                          Pin 03 "BL_ON": 0V
                          Pin 04 "N/C"
                          Pin 05 "STBY 3.3V": 3.5V
                          Pin 06 "GND": N/C
                          Pin 07 "AC_OFF"...
