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 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

Sometimes when I turn on my Magnavox 37MF337B tv it emits a very loud squeal and the picture/channel locks up. I cannot turn it off with the remote. I have to unplug it and try again. When it is on though...


you have some bad caps in the mainboard very common on this model the can shaped devices will have a puffed up top i would suggest you have a tech reaplce them they are hard to get out due to the large ground plain on the board you need a good hot iron
