    Re: Proscan 42LA45H PSU Problem

    let me correct that. I get all of the correct voltages except on which is 0v. This all happened after I replaced three bad caps in the power supply and was running a burn in test. Everything was fine until I turned unit off. I am pretty sure the main is the issue.

        so you have no backlight? main board is sending BLon, so if you have nothing there, then the main board is at fault.

            That is kind of what I thought. Right before I turned the tv off there were raster lines in the video but not in the menu.
