Philips tv 28pw6506

Hi my tv turns on then goes back to standby a few seconds after it turns on. This happens several times untill it stays on. Also the screen takes a while to fill out the sides go wavy but when it turns on fully it is fine. I took the boards out and can no lose or bad connections, plus i blew the dust out while i was there. I did read that it is the capacator on these sometimes the y dont like to go to 12v when they switch on.?  I have done an ellectronics coarse so i do know how to solder and yes i am fully aware that some of the capactors hold there charge after the set is off. Any help as to what is the faulty part and its number or position on the board and the currewnt it should be putting out would be most usefull

 Regards  Charlie

    Thanks for that TVboy I will try it as soon as i can get the bits, i was going down the road of replacing the bc337-25 (2off) ref 7463 @ 7461. I take it that you mean the capacitor at ref 2455 which is 47uf 25v. Thanks for your input and i will give you top marks if you are right, ps I think you are spot on, thanks!

    My TV kept going off as well, when I hit the standby button a few times it would go on again as the picture got wider, until it eventually would stay on - now it's off permanantly. Very disappointed at the TV being less than two years old, and it seems the tube is already gone on it. I'm not an electrician so cannot repair myself.....is it worth going to repair place, or just dump it vowing not to buy Phillips again?

If you need more info please advice. Arpi
