Philips 42PF7520D/10 power on problem

(1/2) > >>

Hello everyone . I brought this plasma tv with a intermitant fault with the on/off switch, i replaced the switch board but the fault is still there.
I have to turn the set on with the power socket when i forst got the set we only ever needed to switch on at the socket about three times no this is what i have to do ...

I get two clicks from the relay then the green light comes on then about 10 seconds later i get sound and about 3 seconds of a picture then the relay clicks off. Then its power off at the socket and on again and repeat this over and over again but for some reason its no longer staying on any more


Please Please some one point me in the right direction on the power board Ive got the correct circuit diagrams of the PWB layout,

What panel is fitted in the set? I think this model has 2

Sammy and an Lg. The set should be treated as 2 different models.

Andy
