Question about Philips Magnavox 20MS233S 20" TV

1 Answer

TV Comes On But No Picture

The power comes on, but when you put a channel on it has static and diagonal or horizontal lines going thru it or a Blue Screen. When you get the blue screen it you change channel on the remote you will get a picture with the lines again. Then if you click on a volumn button you can hear the sound. Started doing this a few days ago and got worse now it won't even get a picture UNLESS (this is the weird part) if you use the hair dryer or microwave the picture and sound will come on perfectly until you turn the appliance off then you get Blue screen again. Any suggestions??

Possible failure in the horizontal section of the horizontal driver or the failure of the line output transformer.
You will have to disconnect the +B to confirm if the SMPS gives the power.If so check for short in this section .

Sony Trinitron: Frozen Static Issue


you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)

Not getting full pic on certain channels


I've seen this problem before. Try to adjust the horizontal settings in the tv. you should be able to adjust the picture up just a bit and it will get rid of the lines. also if you are hooked up thru component or hdmi you should be able to press the # button on your time warner remote to fill the screen. Hope this helps.

Blurry Sanyo TV


Well after playing around with the tv some more, I decided the problem was probably the cable jack, and tried running the video in/out cables thru the VCR to get around this, which I read generally works but in this case nothing. I had tried the tv on various settings, anytime I put the tv in "video" mode I'd get a blue screen and nothing else. Anyway I found a switch in the back of the Direct Tv box for ch. 3 & 4 settings. So I flipped it but still got a snowy picture, only this time it was on ch 4 instead of ch 3. By sheer accident I put the tv back in video mode while I had the satilites setting to ch 4, and the picture came up crystal clear. Since I didn't mess with it further, I'm not sure if it was the channel selector or the fact that hooked the tv up via the video cables, but whatever it was it did the trick.

I just KNEW this could not be a broken tv despite the fact that everhwere I read online suggested it was. I knew pictures can go out, or sound can go out....but to have BOTH go out didn't make sense to me. Anyway, glad its working! :)

White Noise Sound


Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer
