On this TV, the standby LED is lit. When I press the power button, the LED goes out for 1 second, and it comes back on.
I tested the LED strips, and they're all OK. I checked the larger capacitors on the power supply along with the fuses.
I disconnected the cable between the power supply and main board, and no LEDs illuminate.
Here's the voltage readings I got. The second column is the reading I get when pressing the power button. Any voltage in that column changes back to the first column value after about a second.
I don't think it's worth spending a lot of time on this. I would just like to find out which board is likely to be the one failed. Hopefully it's the power supply since it looks like the processor board is a bit difficult to find, and therefore expensive.
Thank you for any help,
Paul
