Hi - Sat,
No info, how about a piccy - Chris.

yup will do, gettin pic back in a while

I have checked voltages at the PSU`s ass end  all seems fine. no un-usual voltage drops. Whilst powering up.

It lights up the tubes, powers up, then in 10 secs powers back down with a flashing standby light. Trying to look for tell tell signs.

The PSU has the high voltage suppy built in to the main switch mode. The back side has the SMD components.

some more pix of the screen in action.

Vertical lines, when i change the remote buttons, i get different vertical screens. Seems like data is trying to show, and its getting currupted. The board at the bottom of the set, the smallest one, must be the panel driver. or to that effect. One of the SMD componets is getting rather hot, when powered up. I got a feeling its this board at fault.
