Question about Philips Magnavox 20MT133S 20" TV

1 Answer

Compressed picture, staticky quieter sound

My new old RX4856 PE02, picture quality and sound were perfect for a couple days (it hadn't been turned on for a long time), then today, the screen kind of flickered and then got darker. Now the picture is compressed and I can barely see the picture. I can upload a picture if necessary.. but tell me honestly: is it time for a new computer, or can i open it up and do something clever to fix it?

    Sorry, I meant a new computer.
    Also, more details: if I turn it off and leave it off for a bit, it's OK for a few seconds before it reverts to the dark phase. Again, this is a kind of older, cabinet-style TV, but one that's new enough to have a remote control.

Sounds like you've got a vertical deflection problem causing the shrunk picture and finally a solid bright line. As to the loss in brightness you may be losing screen voltage to your picture tube. Probably it is time to shop for a new tv since cost of repairs may be too much. Stargazer

Flickers after 5min of use. Perfect sound, turns on fine and excellent picture quality when in blue screen menu mode. Why?

This intermittent problem is very difficult to rectify. Just contact the authorised service center for Hitachi at your town. The work is really a skilled one, that a user cannot do it with ease.

I hadn't had my xbox 360 on all day and when I turned it on it had 3 red rings. No picture is showing up on the TV and the light on the power supply is green.

That is the red ring of death...if your XBOX is less than 3 years old call Microsoft tech support and they will arrange for a replacement unit.

My Korg c15s has a lot of grating staticky noises when played ....I'm told it cannot be repaired as Korg no longer makes parts for this model?

I have a Korg C-15s and also experiencing loud crackling sounds when I turn it on. The problems seems to be either the sliding volume control or the amplifier itself. Honestly though, I believe the issue is the volume control. I opened my piano to get a closer look and attempted to clean the contacts on the volume. Unfortunately after cleaning the contacts, the crackling sounds became somewhat worse. After I turn the piano on, the volume control is generally rendered useless......volume set to low volume and the noise is quite loud and other times the volume control is set high and get very low volume crackling noise. No real consistency. The noise does diminish after a few minutes but so does the piano sounds to an inaudible level. There were a couple of instances where I turned it on and surprising enough, no no noise and perfect sound. For these reasons I believe the issue is within the volume control and not so much the amplifier. I have an electronics background and noticed that the volume control is very unique in design and is not something that can be substituted with another volume control from other sources.

My recommendation is to check the sound quality of the audio from the RCA L/R audio outs on rear of the piano by connecting to a stereo receiver. If it sounds fine you're in luck. If the crackling sound does not diminish after a few minutes like mine does, I would suggest disconnecting the internal speakers and using the audio out only. You can connect a pair of studio monitors or high quality computer speakers, preferably with a small subwoofer to deliver the full audio range and deeper tone of a real piano. I'm currently using a basic pair of Logitech computer speakers and is quite acceptable until I can afford a high quality set of monitors or relocate my piano closer to my high quality Yamaha receiver.

I hope this info helps a bit.

Plasma tv has a smudged picture and colours are mixed

The TV has a color wheel / Light Engine problem.Light engines cost between $800 and $1500. Cheaper to buy a new TV. Get the extended Warranty. It will pay for itself.

Standby/stereo light blinking no picture or sound

My picture would go out after several minutes but I still had sound. I took the rear cover off and blew all the dust off with compresed air.I did this for a few times over several days nothing happened.I also took off the rear circuit board that attaches to the tube with a round pin socket and blew that with compressed air and put it back on. The TV has now worked for two days without the picture going out. It worked!!!!!!!!!!!!!! My TV is 9 years old.

No image but good quality speaker.

Sony has had a problem in older sets with-believe it or not- lack of humidity. I had one with the same problem. If it is under warentee take it back, if not-I know it sounds insane- put a large plastic garbage bag over the turned off set. Leave it that way for a couple of days. do not turn it on during this time. After a couple of days remove the bag and turn it on. If it works-that's the problem, if it doesn't- it's dying, and to expensive to fix. Surprised the heck outta' me when I tried it on my old Sony 19" set- it worked.

Picture goes off and on...

Most likely your Cathode Ray Tube or CRT is going bad. That model number reflects an older TV. What you are describing is a fairly common problem for that television. If you bump the TV and it improves or gets worse then you know there may be a short.. Either way, I would recommend that you use our Premium Service or use our online resources to find a repair person near you. Good luck.
