SOURCE: 36" tube tv. picture fuzzy and out of focus

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.

SOURCE: TV Volume turns down by itself - Philips 29PT8319 Matchline 27"

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.

SOURCE: mAGNAVOX mODEL 27ms3404/17 shuts down

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.

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.

I have 20MC4306. Recently when you turn it off it turns itself back on. Also when you turn it on shuts off after 2 seconds. Tried putting in a video vhs then press play and wait few seconds and hit...


Sometimes when the TV recives a brodcast signal for a new update to the mainframes firmware, it will have to turn itself on to install/recive the update and aslong as it is connected to a power source it can do this. hope this helped answer your question. Have a good day :)

I lost the booklet with all the codes for my remote and i need the code to work my tv my tv is a symphonic


I suggest you try these steps..

1.Turn the television set on by pressing the "Power" button on the set.

2. Find the "Code Search" button on the Philips Magnavox remote. This button will be labeled or will be a different color than the other buttons on the remote (depending on which Philips Magnavox remote you own)

3. Hold the "Code Search" button down for about ten straight seconds. The light on the Philips Magnavox remote should then stay on.

4. Starting pressing either the "Up" or "Down" channel button on the Philips Magnavox remote. Continue pressing the same button until the television responds to the remote. It could take a few minutes for the channel to change so you'll need to have patience when searching for the remote code in this manner.

5. Press the power button on the Philips Magnavox remote once the channel has changes. If the device shuts off, press the power button again to turn the TV back on. If the TV turns on, the remote has been programmed correctly. Repeat the entire process if your remote is not programmed.

I hope this helps...

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
