Question about Philips 36PW9525C 36" TV

1 Answer

TV goes into standby after approx one hour

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.

SOURCE: TV goes to standby without touching it

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

SOURCE: Television reverting to standby

Hi Phil.

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.

Chris..

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.

Technika Tv is receiving power and is trying to switch itself on .the standby light turns green for a few seconds and then goes rd . this cycle repeats itself constantly. Tv will not switch on .


There is some short circuit inside any one of the circuit boards. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact any experienced service technician, or the nearest service center.

My sony KP-443X3U rear projection tv went to standby and I cannot get it to switch on. It is approx 6 years old. I think the bulb needs to be replaced?


Google the model number to locate it with "lamp" and You Tube has video instructions for replacing in most models--lamp has a 2,000 hour or 2 year average life and is meant to be replaceable by the customer who owns the set.

Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

HI,

All I can suggest is to replace the bulb. I experienced a similar problem after about 2 years viewing when the recommend lamp life was approx 8000 hours (I got to approx 3000 hours). There is a service menu you can access where you can reset the lamp hours time. I have read that if this is reached you must replace your lamp, but you can extended this by reseting the hours.

I have since learnt that a lamp bulb can go at anytime, so it is worth having a spare. Also I have noticed that switching the TV off at the switch (not leaving it in standby helps).

Try this to access the service menu. Holding down the menu button on the remote and the one on the TV for a few seconds. I think the TV needs to be off.

From memory, I think it is option 4 and option 5, then reset the lamp hours to zero
