I have unplugged the TV from the wall, and I still get the message: "Retrieving Data", and errors "No Data" or "Not Support" when I plug my Blu-Ray player into HDMI2. The sound comes through on a DVD, but not the picture. The Blu-Ray player works fine in HDMI-side. I appreciate your help.
Retrieving Data and No Data found? That sounds like USB related responses on the TV set. Not Supported could be HDMI or USB.
You actually read that on the HDMI input, not the USB?
Check your TV's serial number
Is it LAQKGWAL or LAUKGWAL at the beginning of the serial number?
Part number -- 3637-0582-0395 sub is 3637-0582-0150
You can buy it here --
That board has your HDMI2 connector on it and will restore it's operation.
Disassembly, remove the screws highlighted in Yellow --
There's some screws on the board and some plugs. Depress the latches on the plugs to remove them, then remove the screws and swap the boards.
Put it back together and your HDMI will now function.
Alright, let me know when you recieve it.
