Magnavox television won't stay on


I know this is going to sound strange but I have something to check. If you have LED lights in your house turn them all off. When they are off turn on your TV and see if your TV stays on. Yes, there could be many problems but this one is cropping up quite a bit. If this does not work then you need to take a look at the power supply board.

My Magnavox digital converter box shuts itself off every 5 minute


Check that you have not got an auto power off setting on. Check that the aerial connections are good. That the signal is strong from the stations it is picking up. Weak signals can cause the box to shut down.
It the box is very hot when it shuts down, you might have a fault on it.

Turning off by itself


This TV probably needs the convergence amp IC's replaced. When they go bad the TV will not turn on.Call a good TV Tech and tell him you want the IC's upgraded to STK 392-150 instead of the original STK 392-120 and check all resistors in the circuit for proper value. They could be burned or open.

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

My TV keeps shutting off


Tvtek is on the right track. The remote will not solve the problem. Sounds like a voltage regulator in HV circuit if it only lasts a few seconds. If it stays on for a couple of minutes, beam limiter cicuit is pushing to overload and shutting unit down. Magnavox set not hard to repair, but a 27" set is not cost effective to repair either.
