Question about Toshiba MD20P1 20 in. TV/DVD Combo
Set shut off during a DVD playback and wouldn't stay powered up after that. It would shut down in about 5 seconds after restart or quicker if another button on television or remote was pressed. Disconnecting from the power source for an extended period increased the amount of time that the set would stay on to about a minute.
The problem is Q401. Change it. It is a 2SC1624 but a 2SC1018 will also work. This solution will work for other Toshiba P combo units.

You have an internal short in the electrical line. your wall a/c [120 volts] goes inside and is converted [changed] to DC [ like a super battery] There are a lot of connections coming out of this POWER SUPPLY[super battery] to FEED other electrical circuit. ANY one of the circuits can demand more then power supply can give and will cause it to SHUT DOWN [turn off to protect itself]
unless u know what u are doing [" DANGER!! wILL rOBINSON, DANGER!!] you should not mess with it.

SOURCE: When I push the power
For sure the power supply is working but the main drive is tripping off. What can be done is to open the set and check on the main circuit if there is any drive component/IC that is heating when the set clicks and cuts.
If so disconnect the power supply and check for a short in this section. Disconnecct the suspected component noticed heating- disconneect power supply to it- and if the set power on then change this compoent.
It can be shorted capacitor, coils,transistor, diode or an IC.
