Replace capacitors 2079 and 2080 with 1000 uf, 50 volt caps. They are on the power PCB at the top as you look at the unit from the rear. Barneyluc.

TV comes on, works for awhile - 15-20 minutes,


You probably have breaks in the soldering on the power supply board.

It can be fixed....but you need to be able to isolate and resolder the bad spots. Plus get the board in and out of the tv.

32 in Magnavox tv model 32MF231D/37


An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.

I have the 26MF231D and it worked great afterward (even though you can't mount it)

Here is how you remove the cover.

I put heat-sinks on U14 and the regulator above it and the TV has been running fine all day. Always shut off after 14-30 minutes before. Heatsinks were just 1/2" x 1" metal strips with silicon thermal compound that I taped up to hold in place to temporarily test, as it is obviously a heat related problem.

If you try it and it works for you, post it here.
