    Hi - I have the same problem and unfortunately, I do not have the manual for the tv as it was given to me secondhand. There is only one difference in when it worked perfectly and now - we connected new cable wire from the splitter to the cablebox because the previous cable wire was too short after we moved the tv setup. If anyone knows how to correct, please help!

    I am experiencing the same problem. Not certain when the issue emerged - TV is used very infrequently. One month it worked, the next time it was turned on, no picture came on and power LED changed from green to yellow after a few seconds.

Just figured this out based on a description of features.

You must power on the TV with the remote control - if you use only the power button on the monitor, it goes straight to stand by mode (the amber light).

Am I diagnosing the problem correctly?

Sounds like a bad component in the power supply. Most likely a bad capacitor.

I have a magnavox model number 32mt3305/17 the green power light on the front panel is on but no sound or picture...just a black screen ...the fuse is good

You have lost your high voltage section, and that is why the TV is in shutdown mode, it has a horizontal output transistor that is shorted, and it is located on a metal heat sink near the fly back. You can have it repair if taken to the shop for about 100.

Magnavox model 27ms3404/17 tv,green light comes on,goes back off,but tv wont come on. saw the same problem listed for another model & was curious if it would be the same repair?

You have a corrupted eeprom! Location IC002. You must see the number of microprocessor IC001 and stereo IC1001 to decide which eeprom to purchase! And always when removing the eeprom to install an eight pin IC socket first. This way you may remove the eeprom in the event you purchase the wrong one or have replace at a another time. Rare but can happen!

Magnavox mf605t screen won't turn on, it stays in the resting mod

This television has a problem with component failure. The reason the television will not turn on is that its has detected a fault in the circuitry and has gone into the protection mode. This stops the television from having a more serious problem during operation. You can call the magnavox customer support at this telephone number. 1-800-705-200. Tell them the model number of you television and about the problem you are having with it being in the protection mode. They will be able to tell you where to take you television for testing and service. I hope this information helps you with your problem.

MAGNAVOX mODEL 27ms3404/17 shuts down after after a few seconds. Mine does the same thing! My TV tube turns black after sew seconds. The green light stays on saying that the power is on. If you change...

first place to start on this chasss is with a known failure in the horizontal circuit. there is a capacitor 2455 and 2 transistors locations 7461 and 7463 that have caused a wide variety of failures. i would recommend replacing these components before proceeding as they could be the whole of the problem.

TV turns on at odd hours by itself

Hi, I had the "Ghost In The Machine". I tried out what I descibed in my original posting.
#1. I unplugged The Set.
#2. I pushed in and held in the power button in for about 5 minutes before bedtime. ( The PC trick I learned) I gave it 5 minutes because a tv set has much more power inside it.
#3. I again pushed in and held the power button in again for 3 minutes the next morning.
#4. I plugged the tv in again. The red standby light was lit. The set did not immeadiatly come on when I tried to power it up.
#5. 5 Minutes later I returned and hit the power button on the remote and it came on like nothing ever was wrong.
#6. It has been fine now for 3 days!!! Powers up when commanded and shuts down like normal. It has yet to come back on or act up as it was doing.
I will keep a watch on it and if it starts up acting again I will repost. I hope this information will be of use to anyone who experienced the same problem. It didn't cost a dime, just some patience. Thanks for a forum that people can exchange information and save trouble and money unless all options are exhausted. Bill

Attention No Video Input

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
