Phillips Magnavox Model 20MT1331/17: It shuts off

Phillips Magnavox Model 20MT1331/17: It shuts almost immediately in repeated attempts to turn it on (this can go on for 1/2 to 1 hour, sometimes longer). Rarely, it will stay on, but then at some point, it suddenly shuts off again. The settings indicate that no sleep setting or other timer is active. I've disconnected it from the cable box to be sure the problem is the TV, and the TV still has the same problem.

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.

With power turned on, my dvd will not eject from magnavox vhs dvd recorder (Model #106.64242401). How do I fix, or at least retrieve my dvd disk?

Probably the buttons contacts inside get "rusted" and stays in ON. Remove power plug. Try to open the front cover, remove pcb and clean all the buttons with contact cleaner, pressing them multiple times to get clean inside. Repeat this procedure 2-3 times. Dry all with a cloth and try testing. If not successful, repeat procedure or change the buttons. Good luck.

Our magnavox model number is 42MF439B/F7 is it set up for internet connection or do i have to go through another device?

Similar model Phillips tv made by foreign manufacturer for both Phillips and Magnavox may help you. Apparently very similar tv sets, so manual should be of assistance to you, although phone contact is for Phillips and not Magnavox.

With a Cable company box connected, that company may provide internet service to you if that is what you paid for.

The tv will not turn on

Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

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

Dvd freezes

If less than a year old, this TV is likely under warranty but should have been taken back immediately to address the issue. I suggest contacting the vendor or manufacturer.
