Hello,
I have my UE55MU6105K TV model that I am trying to repair.
BN41-02568A / BN94-12195C motherboard.
If I disconnect the motherboard from the power board the backlight works.
When the motherboard is connected the backlight works but the screen remains black. The standby LED is on when the 220V is connected, but it goes off after about ten seconds. The TV consumes about 22W, impossible to put the TV on standby mode with the remote control. The main processor gets very hot.
I bought another second-hand motherboard of the same reference (BN41-02568A / BN94-12195C) and with this card nothing happens, the TV does not start and the standby LED is off. The seller told me that his card worked but I have a doubt.
With my CH341A programmer I copied the contents of IC1604 W25Q40CL from my motherboard to the one I bought and the result is that the standby LED is on but the screen remains black and the TV consumes about 20W. Unable to put the TV on standby mode with the remote control.
I did the reverse test by copying the contents of IC1604 from the motherboard I purchased to mine and the result is that the standby LED stays off and cannot start the TV. I see a consumption of 2W (the main processor heats up a little).
Attached is the IC1604 dump of both boards, is it possible for someone to check them if possible ?
Thanks in advance for your help.
