Re: magnavox mwc24t5b

The power supply is shutting down for one reason or another. This unit has 4 shutdown alarms feeding the main processor. It doesn't take much to trip it and believe me, it's a ***** to find it if it is a subtle condition. The VCR could be shutting it down as well if it is not reset exactly right.

This is what I did with the one unit I worked on; It would shut down after 5 seconds. The picture was good when it breifly came on -- but it shut down anyway.

IC1601 is the shutdown opto isolator that will shut off the supply. I removed it and the set came on. After a few minutes one of the power supply diodes started smoking so I unplugged it. The diode, D1618 was bad so I replaced it and the TV worked. But, I could not put IC1601 back in without it still shutting down. I spent hours searching and couldn't find anything. Since it was my son's TV (which he found at the dump) it was OK by me. BUT, if you remove this IC, (it is a four pin located near the yellow transformer) the set will come on no matter what. Just remember, if there is a problem, it will show up quickly. Maybe a new troubleshooting method? Ohms law troubleshooting? No, unfortunately not. Just be careful and try to find the problem.

If you google this model number, you will find a free schematic that --someone-- uploaded to a free schematic website.

I have an advent tv/dvd combo. I dont have a remote and its stuck on video. how can I put it on tv without the remote? thank you

Disconnect the TV\DVD combo from power source (A\C) for two to three days, Replug power cord & see if it returns to normal. 2nd attempt:: Unplug A\C power from wall and take a piece of bear wire or any metal (paper clip, screw driver ) and SHORT the two blades of A\C plug for at least one FULL day.DO NOT PLUG INTO a\c SOCKET FOR ANY REASON !!! After one full day, take the short accross the blades. Replug into A\C power socket. see if that fixes the problem. P.S. Your TV should have a button that switches from TV to DVD play right in the right front.

Magnavox tv/dvd/vcr combo model mwc24t5b i put a tape in the vcr hit play and the tv shuts off. everything else work fine on the tv.

Usually when that happened for me, it meant that one of my small children had also put a foreign object in the slot where the VHS tape goes. Any type of obstruction will cause the VCR to jam and force the television to shut off.

Magnavox dvd vcr combo

YES..............All of these Magnavox TV/VCR combo units have fusses in them. Be aware of the fact that some of these NOT look like fuses. THey're small round BLACK parts which have an F on top of them. They are SOLDERED to the PC board.
I'm very familiar with these fuses. BERNIE

Toshiba TV/DVD combo turns on then off again.

try letting it sit for 15-20 minutes unplugged from the wall and maybe try another outlet depending on if u got plugged in to a power strip, possibly pulling to much power from that perticular outlet.
