How to resize picture on a magnavox mwc20t6

Look for a setting called Aspect Ratio. It will include options like 4:3, 16:9, Zoom 1, and Zoom 2. Then click through the options to select the correct one for your program. Usually older SD programs will use either 4:3 or Zoom 1, while HD programs will be set to 16x9 for Widescreen hi-def viewing. There should be a button on your remote labelled Aspect Ratio or Picture that can toggle through these image modes.

I have a 27" RCA TruFlat TV. Recently the picture

Something has definitely gone wrong. When picture fails, generally the audio will still play; but since the set is shutting down completely after a short time - it is going to more involved.

Firstly, anything can be fixed. The questions to ask are: 1) At what point do you stop spending money to repair a device that is XX years old? 2) How much would a replacement / upgrade cost?

Given that your set is an older SD (standard definition) with an old analog NTSC legacy tuner, it may be worth while to make the move to a digital HDTV. The picture quality will "blow away" any SD version of the same image / program that your old TV displayed. Unlike several years ago, the HDTV has come way down in price, too. A 32 inch, wide screen HDTV price starts at just $235 as results shown by a search in Google. In order to view HD signals, you'll need either 1) a plain UHF/VHF antenna (and local broadcasters in range), 2) HD cable TV service or, 3) HD satellite service. Cable and satellite providers offer SD service and for slightly more, HD service. Most people are not happy watching SD signals on an HD display - so you'll probably want to change the level of service if you're not using an antenna. Old DVD players only send SD signals, you might consider upgrading to a Blu-Ray player. Blu-Ray players provide SD and HD signals - depending on whether you insert an SD DVD or an HD Blu-Ray disk. The Blu-Ray players, like the HDTVs, have also dropped in price significantly.

See if you can find a place that provides free estimates. If not able to locate, find someone that will apply the cost of diagnostics (ask what the diagnostic fee is) to the total repair charge, and decide to either fix or replace.

I hope this helps and good luck! Please take a moment to rate my reply - thank you.

Magnavox 19" TV shuts itself off.....won't stay on

I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

Green screen and distorted picture sound is good but no picture

It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.

Have it service by a qualified person.

I do not have a Zenith B25A02Z TV. What I do have is a 1988 Zenith Color TV SE2517P. I called a local tv repairman and discussed the problem over the phone. He can take a look at it if we bring it in (service call to the home cost $100 just to show up). He said it was worth fixing since he thought it was only the sound. We have a great picture. He charges $20 to look at it but we have to leave it. He lives 20 minutes away one way. We think it is worth the trip if we can get it loaded into our minivan. We live in western NY where the weather can get pretty ugly many days. I will post the solution later when I know. FYI

Magnavox 15" LCD TV

If the LCD only has coax, it will never display a HD picture quality. However, the Comcast HD Box will still display a picture using the coax connection. So, you could watch any HD channel, but the picture quality will not be high definition.

Dark picture and green tint

Most TVs of that caliber have a life expectancy of about ten years.. In 2009 we'll be passing into the HD era and that Tv won't work without a little help from an HD converter. What you're describing sounds like some transistor problems on the crt board and possibly voltage regulation. Not too expensive for a reputable shop, but my best advice would be to get an estimate first. If you need help finding a reputable shop contact NESDA, (National Electronic Service Dealer's Assn.) they should be able to direct you to a member's shop in your area. Its like going to the AMA to find a doctor. If the cost is more than half the cost of buying new - get a new one... Good Luck Bill
