When i worked at Sanyo years ago they produced a chassis called an EH1 which was a 4:3 100Hz set for the German market.

Long story short, but, in certain 'picture' modes some sets would shut down and go into protect mode. It turned out to be a current sensing thing, i think it was found out that it was down to the 'Q' value of the DY winding on some tubes being too high, or it could have been a coil on the board. I cant remember what as it was over 20 years ago now.

So if not remote, look at the picture mode the set is in, see if it still happens in other picture modes and look at any current sensing areas.
