    Any idea how to reset a lamp error on a Sharp LED LC52LE830U

    I'm starting a new thread with this tv because it's a new issue.

    https://www.badcaps.net/forum/showthread.php?t=29947

    I bought this TV due to a lightning strike. I replaced the PSU and got the set to work only to find out the HDMI inputs are non functional. I bought a used main board via eBay and now I'm getting a 1-1 code which represents a lamp error. My original board will let the set power on so I believe the error is in the new main board.

    The service menu says, "Note that after five detection counts, the lamp cannot be activated except in the monitor process."

    I suspect the tv that this board came out of had a broken screen which triggered the lamp error. The original owner may have powered the set on and off with the lamp error to trigger the protection mode. It looks like the only way to reset the board is through the service menu when the tv is working.

    So this is my question. Is there a way to fix this or is the new board junk?

      No luck. As soon as the TV is plugged in, it starts flashing the code. Even with me holding the buttons down while my son plugs the TV in, it just starts flashing and doesn't respond to the touch pads. With the original main board in, there is a relay click when plugged in. With the new board, there is no relay click. I've contacted the seller and waiting for a reply.

        "except in monitor process", any way you can see to enter "monitor" process. Button combination might be different for US model too.

          I can get into the monitor process with the original main board but I can't with the new board. It's completely unresponsive while the LED flashes. I was really hoping to hear of an EEPROM reset or something.

            If you have the service manual find out how you enter service mode you should be able to scroll down to reset lamp error activate that do not touch anything else

              It won't let me into service mode. It won't turn on at all. It never goes into standby, it just flashes the 1-1 code continuously until you unplug it.

                Most new Sharp TVs have a service mode that can be accessed via USB. Have you tried that?

                  Heya, I've got a 46' 832U with the same issue. Were you ever able to get this working?

                    I wound up putting a new main board in it.

                      So even though the LED flash code on the front was pointing to the LED/Drive board (big one, center tv) it ended up being the main board (smaller board with A/V inputs) that had to be replaced?

                        As the original post says, my problem was no HDMI's. This was an eBay main board bought to fix that. When installed in the TV, the LED flashed 1-1. It had apparently come from a set with a bad LED strip in it. I had to get a refund from the seller.
