Thoses sets have alot of problems. Personally,I don't fix them any more because they just don't hold-up to repairs and one thing after another go bad on these sets. Most notable is the small digital "daughter board" on the left side of the set. It slides on the main board on edge like memory for a computer. Those are $350.00 if you can find them. Don't waste your money on this set...please!! I've been a T.V. repairman for over 20 years. Put your money elsewhere....and buy an extended warranty!. Stick with Hitachi,Pioneer,Panasonic,Sony or the real Sharp sets. Sharp used Funai for the low end sets. Nothing lasts anymore,but with the above mentioned sets,atleast you have a chance on getting service/support when trouble comes. Most everything else is disposable...no parts available. Do your homework before buying and don't EVER buy "Made in China".

Magnavox 37" model 37mf231d-37 wont tun on when i hit power button the screen lights up for a secongd and turns right back to black and the power button green light comes on and right back off I found


Your power supply is weak. If you think you can repair this I will tell you how. If you cannot do this,find someone who works electronics and share this repair. Two capacitors are bad. When pulling the back cover off, you may see one or two capacitors bulged. Even if they look good....replace these capacitors. The locations are numbered and, the capacitor having a value and temperature of 105 degrees.. Location of the first capacitor is 2074, value 25volts @ 2200 mf @ 105 degrees and will most certainly be bulged. The next capacitor may look fine....replace it. That capacitor location is 2066, value is 35 volts @ 1200mf @ 105 degrees. When you replace these, please be sure to get the polarity (positive leg and negative leg) of these capacitors seated correctly...this is a must. This will correct your TV. You will save lots of money, because you asked. Thanks for listening ..good luck...we will be here for your next repair.

Magnavox rear proj (model# 8p6044 c102) pic is cloudy/green tint


Yes the coolant gets crud buildup in it over time which will cause the color and clarity to get very poor with obects that will glow around certain bright ojects. You can get the Phillips CRT coolant replacement kit from www.tvrepairworld.com which has the CRT coolant for all 3 CRTs and also includes the Cd with instructions on how to do the replacement.

Power light comes on and goes right off


Take a look at the blue round capacitors. They stand on end and about the size of a dime and 1/8" thick. They should be by the highvoltage transformer. That's the plastic box with a spark-plug wire sticking out the top. The circuit board should have numbers printed by the parts. Look for c811 or C8** . The C means capacitor and the 800 numbers means the circuit it's in. This is a horizontal output capacitor your looking for. You will see it burnt. Might not be blue...could be yellow or orange. But you should know what kind of capacitor to look for by the description I gave. This seemed to be a problem with these sets....or atleast one problem of MANY. If it's not that, then you need big time service. I wouldn't waste your money on a Magnavox. They just don't hold-up to repairs very well. If you find the burnt part, let me know what the location is...C8**....and I'll tell you what the value is. You won't beable to read it if it's burnt. Now atleast you know what your looking at. Sometimes if you have someone turn the set on while you look at the board in a dark room, it will spark. Hope that helps. Good-luck.

Same problem. The power button does not work. The volume and channel buttons turn the tv on. the tv then shuts its self off 15 seconds later. the red light blinks in second intervals while this happens.
