I have a new sony what did exactly the same thing,switching on and off randomly and it was just dry joints.

My television is 5 years old, but has been turning itself on and off at random for a couple of years now. Just lately the problem has been getting worse. I twice emailed Hitachi who did not have the curtesy to reply. I telephoned them only to be told that this turning on and off of the television is a SAFETY feature indicating that there is something wrong with a component. They were quite willing to give the telephone number of a local authorised Hitachi engineer, but not willing to admit to a common fault of any sort.

Hello,
Apart from checking all stabiliser ICs', links (solder top and bottom), etc.and checking for poor connections, there was a mod., to add a spring from the top of the wire clamp on the LOPTX, to the heat sink of the line transistor -(this was for the set going into standby, but coming out, if switched on via the handset.)
Best of luck

Most models of that era have a Known fault of the Regulater IC going dry joint. Pads are very small and you need to clean away to enlarge B4 soldering
