Magnavox 27MT5405 screen turning green on and off

My magnavox is less than 2 yrs old and the picture is turning green off and on. I called tech. support and they said that the tube might be going and that I should contact a repair shop...where I will have to pay for it!..because the warranty is only good for one year...of course!! I am wondering how many other people have had this problem around the 2yr mark. Perhaps magnavox should do something to compensate people if this seems to be an issue amongst the model, not just one televison.

Check your input cabling and connectors and make sure you have a good input signal. Put another tv on this same input cable and see what happens. Keever

Magnavox tv about 11 years old does not turn on at all what is the problem? all connections are ok

Magnavox are a generally cheap brand of television so 11 years out of the product is a good run

i would assume that the power supply inside the Tv has died, you could probably get it repaired, but it would be most likely cheaper just to buy a new TV.

Philips rear projection color and pic problems

I had the exact same problem with my Magnavox TV. The screen would shrink then expand. After thrity minutes it would correct itself. Then one day it just broke - no sound and no video. I searched these forums but did not find clear instructions or kits on how to fix it. I gave up and called in a repair tech. He fixed my TV in less than 30 minutes.  

To help others I documented the fix and created a repair kit and step by step quide on how to fix the problem. You can find it here.

Brad, AV-1 INPUT, be advised this will use up the AV1 port so if you have another item that uses regular AV cables you`ll then have to use AV2 for the video in and L&R audio in, enjoy, BMW Rider

51" Magnavox projection TV

I had the a similar issue. My TV broke - no sound and no video but the power light was still on.

I gave up and called in a repair tech.

He fixed my TV in less than 30 minutes by replacing a bad IC chip. He informed me that this is a very common problem with the older Magnavox TV sets and that its typicaly the same chip that fails.

I spent over 300.00 for the repair. The parts cost less than 20.00.

To help others in the same boat I put together a how to guide and parts kit on .  I'm not sure if it will work for you but it may be worth a shot.

60" Philips Magnavox Projection TV Red Screen

You can also check to see if you have bad fluid problems, by looking down in your crt's with a flashlight when you unplug your set and see if you can notice any particles that should not be there. Look at all three and see if there is a difference. It should be clear, if not then you need to change fluid and clean.
It sounds as if one of the picture elements (there are probably 3 for R-red G-green B-blue) has gone bad and it is most likely the green one. Sad to say it will probably cost you more to have it fixed than it would to buy a new TV. Most places will not even look at a TV for less than $85 or so, then they will add parts and labor... if they can even find parts.
