Open Question

MagnavoxTV model number 19PRC2 3121, serial number 43824079

A loop promotional piece is now running on the tv set and I am not able to interupt the run or turn off the set. It is an older set but has been doing fine until now. What, if anything, can be done to restore sanity?

SOURCE: Standard TV-Auto shut down

TV's have a circuit that monitors the high voltage and shuts down the set if it senses something amiss.
Figure on replacing the flyback transformer.
However, my experiance is to not put money into a TV that is over ten years old. TVs stress out their electronic components worse than almost any other electronic product. After 10 years, there are so many parts that are ready to fail that your are probably wasting your money trying to get any more life out of it.
Another option is to wholesale replace the main board from an outfit like PTS Electronics at
Hope ya fix it!

How do I get my color back and closed caption off my TV. I have my Phillips Magnavox TV serial number TS2544c122/ The remote to controled with our dishnet one. I need to get my color back and closed

Sounds like you might have switched display from pal to NTSC or vice versa.this is usually the first thing that causes color to drop out.if not you will need to go through menu settings to check if you have rgb or similar color controls that are not set correctly.i assume you have already checked the saturation has not been turned down.sometimes the remote buttons can stick down or be under a book or cushion which will alter tv controls without your input.

The outputs from the dvd that you are describing are that of line level and not you don't need to tune the tv to just need to put the tv on the video source setting(video1,2,3 etc..)..if you have the remote..there should be an input buttton or a source button

Lost the remote for my toshiba tv model 27a32, need the model number to replace the remote (prefer to get a toshiba remote rather than a universal)

The model number will be on the back of the tv. You'll have a model number serial number and a few other numbers. But for the price of a factory remote you can get a really nice universal....

TV will not turn on.

A high pitched whine is most of the time the power supply trying to run, but it is being loaded down from a short somewheres in the set. Sometimes a resistor on the CRT board will open and make the set shut down right after start up, sometimes the horizontal output transistor causes this problem, almost any circuit for that matter can cause this problem. Good Luck

Hitachi Multisystem TV model # C2980FS ..not powering on

First off you gotta tell us whats the right model and make as you have two listed here and both of these flybacks are avail. trough The parts are not listed online but get the toll free # or leave a message for them to get back to you. Now A flyback is not a user replaceable part for starters. It is soldered in and theres very high voltage inside these sets even after they are unplugged, and its not adviseable to replace a hi-voltage part in a set, unless you know the issues involved with replacing such parts. Good Luck
