I have tried scart to scart as suggested by Dave. I didn't have an aerial plugged in, but the graphical menus showed up without any problems on the other tv. I was hopping for a psu fault as that is the easiest fix, could still be at fault? If not, what repairs am I looking at? Tcon (timing control board?) was mentioned, can that be replaced without replacing the screen by some means? Is that the little the little circuit board above the main board, under a foil cover and connected by LVDS?

Another observation - this fault seems to be heat related. If I use a hair dryer to warm the inside of the tv when turning it on, it only takes 3-5 minutes for the video to appear, instead of the usual 20-30 minutes. Could it be a loose connection on the lcd controller board which closes when the metal casing extracts when warming up? Or is it some electrical component changing its characteristics when warmed up?
