How can i fix my panasonic tv, tx-w28r4dp, chassis euro 5?

When I switch the tv on, it 'trips' off back to standby. It used to stay on for an hour or two, but not any more.

dry joints/and or failure of the field op ic can cause this too...

Usually due to short circuit line output transistor Q551.
There is a repair kit for this part: Kit number TZSSEK001.
Includes new transistor 2SD1577LB for improved reliability.
