Re: picture goes on and off

Check the base socket, and the problem is not clear from your post, is the picture in focus when it appears at first? If it is not in focus and faint, changing the crt base socket will fix the problem

When you turn the tv on it goes to the settings screen and you can't get a picture for about 20 minutes until it warms up

Fist is contact Philips to see if this (with the model number) is a known issue or if there is a software upgrade available for this set.

I sorry to say I think you have a component failing that is related to heat. 15 years is a long time and if the TV was used in hpot conditions over the years it may well be the proble, or it's just old.

Tv turns on and off by itself

Picture tubes rarely go bad. You have a bad connection or something on the circuit board that is breaking down due to the temperature change . Probably an easy fix. Not something an unqualified person can do though. Your local shop should fix this for about $60-100.

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck

Tv clicks off

You most likely have dry joints. If you are not competent with soldering and electronics, you should take it to a qualified repair person. They should not charge you more than £10-15 for repair.
