      It's an LCD.

      You weren't clear on the symptoms but I'm guessing all too common no sound problem from your post.

      The 3.4V output on the PSU is defective (measures low) and that will cause no sound.

              Yes, bad 3.4V output almost certainly, very common issue.

                      No, but I know the 3.4V is on the PSU, and the PSU outputs are labelled, you need to take a few pictures so we can see the chassis layout of this TV.

Basically everything works fine except for the heavily distorted sound when the Subwoofer module is connected and there is a buzzing sound coming from the PSU PCB.

                                                                                  This seems to be a rather rare TV so there is not much prior on topic help to be found however a service manual is available at the usual sources (Electro Tanya i.e.).

I took it home and plugged it in, I her a click, then a second later another click, and nothing. Dead as a doorknob

The power supply appears fine, I checked the VS, VA, and 5V voltages and they all measured correct, on the power supply board and on the display boards (Y and X boards). All the fuses are fine

To be exact i have 2 of them and i use them professionally for my small FM radio station here. The first one works like a charm, but the second one does not work at all.
