SOURCE: My magnavox 37mf321d 37 LCD tv

This is a bad power supply and an easy fix. Their are several electrolytic capacitors on the power supply. If one is bad it will have a bulge on the top. Mine had a bad 2200uF and a bad 1200uF capacitor. About $7 worth of parts at Radio Shack. Radio Shack had the 2200uF but it was axial leads instead of radial. (leads come out of each end instead of one end) but It will still fit. They only had a 1000uf capacitor so I combined that with a 220uF capacitor and wired them in parallel. Make sure you put them in with the correct polarity.

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.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.

What connection do I need to use Magnavox 17" Model 17MD255V/17]TV/DVD as a monitor on a computer? Error message says "No PC Signal" Monitor cord is on. Power cord is on. What's missing? thx


You need to let the Magnavox know what signal it should be displaying. Look for a "Source" button on the remote or menu and choose PC or whichever slot you are hooked up, say HDMI.

Magnavox 15mf605t/17 15'' LCD HDTV won't turn on


Have similar TV. If it is set to the PC source, it goes into standby when there is no signal, like a regular monitor. Even though the monitor is in standby, you can still press the Source button to change to, say, HD input, and will use the familiar on/off action when pressing Power on the remote.

A little weird, but I've gotten very used to it.

I have a Magnavox 51" Projector TV. Model 51MP392H/17


Hello bullmuscle,

This is a power supply problem, I would suspect the HV power supply because the primary and secondary supplies anymore are tied to the HV power supply. This type of repair requires certain pieces of equipment, to test voltages, look at signals, and to if need be test for shorts in inductors (Switching PS transformer and Flyback transformer). I would not recommend that you try to fix this yourself, The cost for this type of problem is not that expensive and can be done in one evening, if the parts are available. You may be fortunate and it could be just a blown fuse, in the HV or LV power supply circuit

I hope this helps,

Thank you,

Shuttle83

Problem with Magnavox 15MF605T/17B


Hi SgtHoagie and anyone else:

I ran across this problem too, at 1:30 this morning. At that time I had to get out of bed and try to figure out what the hell happened. It seems that my flat panel TV somehow got switched over to the computer monitor mode. When this happens, the light will turn an amber color. On the bottom of your flat panel you'll see some very small buttons, marked "MENU," "CH" "VOL" and "SOURCE." You'll want to click on the "Source" button and that will switch your flat panel back to the TV mode. Your flat panel TV can also be also used as computer monitor.
