Question about Philips Magnavox 27MS343S 27" TV

1 Answer

TV turns itself off

This TV is a little over a year old. It is a 27" Magnavox. All the sudden for the last 4 mos. when we turn it on it turns itself off at about the same time the channel display disappears. If you continue to turn it on it will eventually stay on for about 8-10 min. then turn off again. Any suggestions?

Magnavox 19" TV shuts itself off.....won't stay on


I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

The little button on the main circuit board may be sticking intermittently causing your set to do this. This little push button was operated by the piece your 3-year old broke off.

Sony Wega KV-27FS100 RANDOMLY Turns itself ON


You said around 4pm TV is switched on everyday. Check in menu options any on-timer and off-timer is changed. If it is not there is a problem in microprocessor section. EEPROM ic malfunction also shows these type of symptoms. But it can be done by Technical persons only. This is not a major problem. This is due to surge current and lightening like that.

TV turns off/on by itself


thats why you got this TV for free I'm afraid. Your problem will cost more then the set is worth to have it repaired. Unless you understand how the differant circuits work, and know how to read a schematic, follow the circuit flow, and use a multimeter, this will not be an easy fix for you to do. There are components in the power supply that need to be replaced. Good Luck

TV won't turn on, makes high-pitched clicking noise


Its a real good chance that the HOT (horizontal output tranistor) transistor is shorted if so the flyback trasformer may be bad also. the transformer will make a tick tick sound if it is trying to start.
