Question about Philips 36PW9525C 36" TV
Can anyone help. My tv works fine for about an hour then switches off and goes into standby. It can be switched on again but then goes to standby after about ten minutes. I've had this tv for six years now and this is my first problem with it. Any advice would be most appreciated. Many thanks. Maurice
Capacitors that are going bad in the power supply is the usual problem. Six years, however, would be a long time for this problem to show up. Cheapest fix is (in order): (1) Replace all electrolytic capacitors in the power supply board - about $20.00 for parts. The really, really big high-voltage ones are probably OK unless you see a bulge in the top.
(2) Replace the power supply board entirely (with new one - not used from eBay) (3) Come back here if these don't fix it. I have fixed many TVs with this issue and 90% is capacitor related.

Soounds like the typical cold or bad solder connections somewhere in this set on the printed circuit board. Not the ez fix for a consumer. Must know how to solder and test solid state electronics

OK sorted the problem on my set. Replaced the capacitor ref: 2455 on main board it is a 47uf 25v but i was told a 35v will work as well? But mine is a 28pw6506/05

Try adjusting A1 on loptx it is very critical & can cause the symptoms you are describing.
You could be right in saying the crt, Philips tubes are notorius for failing.
Im hoping your a tv tech if you are not DO Not do what I have written below tapping neck to hard can cause seriouse injury to your self.
Run set & tap the glass neck of crt if pic flickers or you see red blue or green flashing while tapping tube neck it will be the tube.
Let me know results there are a few things that can be done.

Your power supply is probably failing, and will need replacement or possibly repair. If you're very good with a soldering iron, and very comfortable inside a TV, you might ba able to repair it yourself, but I would really recommend that you take it to a professional be cause it's easyy to get something wrong and cause a more expensive repair.
