    Eeprom

    Does anyone know anything about EEPROM on main board. I have an LG tv that has 5 EEPROM on it, is this normal. I have a plasma tv that has all the voltages present but when the main board is connected, I lose the VA and VS. I tested the SDA and SCL on all of the EEPROMS and I am not getting the normal square wave output. Do I need to replace all of them? The part number is WINBOND 25Q64BVFIG.

    The YSUS, ZSUS, YDRV module are ok? Check the PSon signal. W25Q64BVFIG is SPI FLASH memory, it is possible to have bad software or bad block/sector inside.

          What model of LG plasma tv is? To test W25Q64BVFIG you need eeprom programmer and SOP8-DIP8 adapter.

            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...
