So... what have you tested so far? Should we just throw random guesses out? Maybe try checking PSU voltages. Any LED blinking? Check service menu (062596 then info+ or sometimes info+ 062596) for error codes.

I had nothing on the tv could not find a book all voltages seem to be right no error leds at all

What's the chassis code? If unsure, post a picture of the model # sticker. Voltages OK when it goes off? Does backlight go out? What about sound?

Nothing stored in service menu

Everything goes off on it then resets

Chassis is FJ3.0ELA.
Service manuals can be found on my site, as well as elektrotanya, servicemanuals.pro, and possibly many others.
So when it goes off the power supply rails, do they drop out or not?
Does it reboot immediately, or do you have to turn it back on?

Power drops slightly it seems to stay on when there is nothing plugged in but as soon as hdmi or scart goes in it starts going off it drops from 15.68v to 14.47v and it restarts it's self

WHAT drops from 15.6V to 14.4V? What is it labelled?

I don't know every TV chassis off by heart so if you would be as kind to highlight this component on a photo I might be able to make a guess. What about the answers to my other questions?

Re: philips 32 lcd keeps going on and off even when all caps have been changed

I'll get a pic in a mo for you I put a video up to show what it's doing it turns back on its self

[adamp91gvm]

Re: philips 32 lcd keeps going on and off even when all caps have been changed

Just there to the audio board

[tom66]

Re: philips 32 lcd keeps going on and off even when all caps have been changed

No idea if that's OK, but if that part is only for audio I would exclude it for now. The way it turns off almost looks like panel 12V fails and it might be resetting because of this, try locating t-con board and check fuse voltages.

13 v going to the t con ?

[tom66]

Re: philips 32 lcd keeps going on and off even when all caps have been changed

13V steady? Or not?

[adamp91gvm]

Re: philips 32 lcd keeps going on and off even when all caps have been changed

12v now sorted voltage on t con but still goes off as soon as I plug and play my blue ray through hdmi

[adamp91gvm]

Re: philips 32 lcd keeps going on and off even when all caps have been changed

Yer its steady till it goes off
