3 minutes after turn-on, picture gets scrambled
It could be the transformer on its way out on the power board, unplug the tv and take the back of, Trace the the power cord to the transfomer which will be a big square componant, take care not to touch any capacitors, they could still be charged, and have a look for any dark marks on it and check for a burning smell. It'll need to be changed if you do.
Also have a look at the capacitors andand check to see if you can see any signs of leakage or slightly dommed tops, the capacitors should be completly flat at the top. They'll need to be changed if there are any.
Also there is normally a small fuse on the power board somwhere, have a look around and you should find it, it might be worth swapping it out.
