LG 50PT350 - No picture - No backlight

[fcisolutions]

TV Gurus, oh how I love plasmas lol. The VS and VA voltages (205 & 55) are fine when I disconnect the main logic CTRL board from the ysus. When I plug in the CTRL, the power supply will click on, and then back off. But I still don't get backlight with the CTRL disconnected. Please help.

I think you are working on to many TV's at once. Getting your plasma mixed up with your lcd's

Should I just try another main logic ctrl?
