Question about Philips Magnavox 20MS233S 20" TV

1 Answer

Magnavox 20MS233S The tv turns on for about 5 seconds or at least makes that high pitch whinning sound, then stops. After that you can hit the power button again and the same thing happens. The screen shows no signs of life at all. No lines, flashes, nothing.I have no warranty. If you have any suggestions let me know. thanx, Zach

    The tv has not been damaged or moved. It has been left on all night long many of times. It quit in the middle of the night. It only worked for eight months and now it's been sitting in a corner for five months. I suppose dust could be a problem, but it's not that bad. The reset test has not worked. If you have any other info it would be greatly apprieciated or I'll turn it into skeet.

    turns on for almost a minute, then clicks off. will not respond to

    any button pushes at all afterwards.

    if it is unplugged for a minute, then plugged back in....the cycle repeats

    what would that be indicative of ?

    a bad capacitor? transistor?...diode? (zener maybe), or maybe a temperature compensating diode, i dont think its a resistor is it,...if

    it was a resistor it would'nt turn on at all, right?

Has it been moved latley? try to unplug it over night then try it. Sometimes they need to be reset. Some tvs go threw a test phase and need to do it a few times. If it has taken a fall it could be damaged or somthing may have come unplugged internaly. It may have over heated is it free from dust? electronics attract dust like a magnet. Is there any signs of somthing spilled on it? water damage?

27 inch tube tv won't stay on

You have a problem is in your horizontal section which also is part of your power supply. The high pitched whine is from the Intergrated High voltage transformer (also called the flyback transformer). This sound occurs when the freuency of the transformer changes and or the voltage gets too high. The click occurs as a result of the drawing of excessive current by the HOT Horizontal output transistor. This is repairable, but requires the correct equipment and a schematic.
