How to fix my magnavox LCD tv, the picture went out, have sound

Hi Daryl, This is a common problem with LCD TVs. Back light failure is the cause in most of the cases. I do not think you can do anything about it yourself. Please consult a local TV tech. Good Luck

Magnavox turns on then goes off model 37f337b/37f437b

More than likely power board,usually repairable,look for blown capacitors.A blown capacitor will look like the top is rounded also suspect capacitors will show signs of the plastic coating shrinking .

Magnavox 32mf231d - Just a blinking green light, No Power

I had this problem, but saw other places that it was a cheesy capacitor on the power supply circuit board causing this. I opened it up and took the power supply board out and it was obvious which capacitor was bad...top was bulging and had black stuff on it. It was rated 2200 uF @ 25V...got a new one @ Radio Shack that was 2200 uF @ 35v. Soldered it in (I stink @ soldering, but gave it a shot and it was EZ). Watching the first weekend of college football w/o waiting on a flashing green light for up to an hour so the TV would start! I'm going to try to find the other websites that directed me to this to say THANK YOU...BTW my brother used to have fits with several Magnovox TV's and thier power supplies back in the old tube style TV days. I thought I didn't need to worry about this with an HD flatscreen, but was wrong. I will think twice before buying a Phillips/Magnavox/Funai/whatever else they are again. They have a long list of complaints and I believe a class action lawsuit to refer to about this problem. They should have stepped up and done something!

Tv powers on and after a few seconds turns off. does this several times then will eventually stay on

hi this may be a power board fault, usually capacitors that bulge up or shorted transistor or diode regardsshaun

Magnavox tv turns off by itself

hello, i don't where you live but there are no analogue signals being broadcasted any more. if your in england you will need a freeview box, some tv will switch off if they are not receiving a signal regardsshaun

Popping in speakers then lines through picture sometimes no sound

Likely bad audio output circuit---it will usually be part of the main board in these sets----not likely to be a do it yourself repair.
