Question about Philips Magnavox 20MS233S 20" TV

1 Answer

Picture beginning to fail

Lately I've noticed that near the top of my screen, the picture is beginning to get distorted, about an inch vertically, and it goes all the way across the screen. The picture in this area bends heavily to the right, and is much brighter and more vibrant than the rest of the picture. I've also noticed that the picture outside the screen isn't quite as brilliant as is was before. When I turn the TV on, the top of the picture is actually about two to three inches from the actual top of the screen, and it slowly moves upward as it warm up, until it reaches the top of the TV where it should be, but it dips slightly in the middle. I'm really unhappy with this thing. I took a chance buying a Magnavox TV because I've always found their TVs to be lacking in many different areas. BUT I liked the sound setup, and it looked as though they have come a way since I last owned one, but alas I've been fooled.

    Well, the unit is just over a year old. Its really a disappointment. Any idea if this is something I can tackle myself? I'm fairly good with electronics, and in my spare time I build LED lights and what not... so if its something I can cut out and solder in a new component I should be good.

There are some components it the vertical deflection amplifier area that are becoming thermo sensitive with age. It is also possible that there will be parts going off value in the power supply and other areas.

These problems are typical in these sets when they are aged. The cost of the repair may not be worth the investment.

You should take the set in to a service center for an estimate.

Same Problem - Sony Trinitron picture dies out


You are probably dealing with loose solder connections in the horizontal and vertical deflection circuits. I am surprised it hasn't failed in a massive way yet. Too many times that is the way it ends unless those solder connections are taken care of.
Hope this helps,

Vertically short picture


There is a bad capacitor in the vertical circuit. Look for caps in the same circuit and either check or change them. If hte vertical IC is listed as IC301 for example, the caps in the same circuit will be marked C3xx. These are circuit designations that are printed on the board. Look for caps with values of either 47ufd or 100ufd. These are the most common ones to fail.

Keep us posted,

sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem. good luck.

Picture problem


Sounds like you are in the begining stages of vertical foldover. This is a problem where the vertical driver waveform is distorted due to a component failure causing the beam to not be driven all the way to the top of the screen. Usually there is enough overscan that you would not necessarily notice the picture being smaller than the crt. When this happens the horizontal scan lines, which have not decreased, are all displayed on top each other or as the condition worsens they invert. This causes the symptoms that you described. The solution I use is to replace all the electrolytic capacitors in the vertical drive circuit. There may only be one bad one but finding it will drive you nuts. They only cost dimes so we're not talking much money. Without a schematic you can usually be successful if you replace all the electrolytic caps around the vertical IC. If you are going to tackle this be careful. TVs are dangerous. Remember to unplug the set and discharge the crt High Voltage anode. Good luck.
