    Sharp LC-40LE431U Manual control buttons not working properly
    by DRIFT-O-MATIC
    I have a Sharp LC-40LE431U TV. The symptoms are when plugged in, the control buttons on the right side panel don't seem to want to work correctly. I get a solid red light. But when I press the Power button, it does not power on immediately. I have to keep pressing ALL the side buttons randomly until finally the solid green light is on. Then when pressing each additional button, they do not always respond correctly, if at all. Pressing the Volume button might bring up the Menu, or vise versa. Even if I can get the Menu screen to come up and scroll through the selections, I still cannot select any...

    LG 60PK550 Logic Control Board EBR63450301
    by Yanleb
    Hi all, I just want to share the repair of my 60PK550-UA TV set.

    The TV set was powering on, just no image. After verification, nothing wrong on the YSus or ZSus boards. Nothing wrong on the main board either.

    But I noticed that the LED was not flashing on the Logic Control Board. This is an EBR63450301. The LED is supposed to flash even with all the flat cables disconnected, with only the power cable attached.

    All the voltages measured at the electrolytic capacitors on the board were good. From top left to bottom right:
    C57: 3.30V
    C61:...

    Pioneer VSX-522-K remote control not working???
    by tmhobadcap
    I have this receiver for at least 10 years. Usually, we just use the remote for turning on/off and adjusting the volume. Recently, the remote control started not able to turn the receiver on. Later, the volume also could not be adjusted by the remote control.

    At first, I thought that it was the usual problem which can be fixed by cleaning the contacts on the switches and the pcb. I opened the remote and clean it with alcohol. The remote did work again after that. But after one day, it did not work again. I opened it again and clean with alcohol and contact cleaner. Again it worked...

    Driving a Sharp TCON/panel with a universal main board
    by advant
    This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

    I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...
