It sounds like you may have a G1 intermittent short in the picture tube, which unless it is still in warranty would not be worth repairing.

Most likely the volume down button on the front of the TV or the switch that it activates is sticking. Should be an easy fix otherwise.

first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

SOURCE: 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

Sony Wega 32 inch tube TV buzzes when turned on and then shuts itself off. If you turn it on several times the picture will stal on


look likes E H T problem. Watch the rear of the TV. If you find blue arc anywhere, you have to check that component. Take care while handling the E H T side near the picture tube.

Even if the TV is disconnected there me dangerous voltage present in the E H T connecting point of the picture tube body. Take service center help.

36" toshiba suddenly turns off and the little red light flashes


Some el.components are loose on tv circuit board.I have removed the back cover,supported tv picture tube 45 deg.against wall.This tv is heavy!One screw on left holds the circuit board to bottom case.Removed and supported this board on few heavy books.Turned tv on and gently probed all the componets on top of the board with plastic drinking straw.In my case transistors Q-830 and Q-421 needed resolder loose joints.These components are mounted on flat aluminium heat sink strips located sligtly left of center of the circuit board.Also blobed bit of silicone into base hole and foot of alu.heat sink to support it.

Magnavox 27MS3404/17-Turns off at random


There is a component in the power supply or one of the scan amplifiers that is going off value, and thus causing a protect or shutdown condition.

Take the set back for warranty service, or have it serviced if it is out of warranty. This is not something you will be able to fix yourself.
