I have recently been given a TopVision PT1503N monitor TFT that is in non-working condition. It appears to have a power supply problem that I can't get sorted out. The unit is completely dead. No power - no indication of power. The DC 12V is on the powerline inside, but it won't startup when the power button is pressed.
I'm wondering if anybody knows of a schematic that is available for this machine. I have 3 of these LCD monitors with the same problem! Any help appreciated. Loek Stolk.
