We have an older Phillips Magnavox tv. The tv will turn on & we will see the picture for a short time but then the screen turns grey. We still have sound, just no picture. Also, the green power light...


Hello, the grey screen could be due to a missing 220Volt source which feeds the color (RBG cathodes)inside the CRT(picture tube). When this happens the beam current inside the CRT goes high in a matter of second, thus triggering the beam current protection circuit(blinking green light)shutting down the TV. Repairing the secondary voltage source is necessary to get the TV working normal, a good technician should be able to repair it for between 80 to 100 dollars parts included, except a picture tube, which could be also the cause of the problem(K-A shorts).

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

Phillips Magnavox Model 20MT1331/17: It shuts off


The poster, Jim K, is probably in possession of at least a layout of the power supply and the 'location' is likely derived from a grid used to physically find parts on a board.
220 uF is a common value for an electrolytic capacitor and the 200V is the rated sustained DC voltage it can tolerate. 
The 130 volts could be caused by a capacitor that is failing and not smoothing the rectified voltage as it should.
In other words, you kind of need a tech.

Phillips/Magnavox 9P5544C102 white raster and shuts down


This denotes a problem called blooming the horizontal lines you see are called retrace lines this is caused by the increase in anode voltage which could be caused by an increase in HV section current which trips the overcurrent protection dircuit and turns the TV off.If you do not have electronics experience I would suggest taking the set to a TV repair shop.
