Well that's funny 'cas the end cap is wobbly on my Sony Trinitron which is turning itself on and off rapidly after warming up, and if I thump the TV it sometimes comes back. Do you think it could be that and not the soldering on the IF can which was problematic on these models?

I don't want to take this OT but if your Sony is the chassis with the small soldered in i.f. unit I would suggest it is! Remove the unit from the set [solder pump] slide out the p/c board and resolder the joints on the filter coils and any others that look dry. Put it back together and thats it. Regards John.
