Hello.
Got round to checking p.s. C877/C878 are not fitted on this p.s. 17PW22-4, and unfortunately heating/freezing has no effect, When the set eventually does come on ,no amount of freezing will bring the fault on! Weird eh!
But leave it switched off for a few hours and the problem returns!!
The main board is type 17MB12-2
