A loose contact on the mainboard, if you know how to solder then have patience in soldering what you can see in the mainboard that may be having loose contact.

The TV will shut off by itself randomly (anywhere

Sounds like the TV is going into the "protect mode", usually means there is a failure present and it's shutting down to ward off any serious damage to the electronics. The status light will usually blink a error code along with this symptom, call a service center and let them know how many times the light is blinking in a continious pattern and that will help them to diagnos your TV problem. Good luck and Merry Christmas!

Toshiba TV

Will not power, led blinking
check R640 (1K 1/4w) if open replace ic600 (8-759-670-30)
Standby led blinks slowly, a few times, chassis won't start up
I changed the vertical deflection ic type TDA8170 and I measured two leaky capacitors in the power supply. Better to change all 4 capacitors in the power unit, everything was then ok !

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.

TV refuses to stay on

I'm the OP of this, and what I did was had it unplugged for about 2 days, plugged it back in and it has worked since.

TV keeps turning off after 30 seconds

This is usually a sign that a function has not completed or a switch has stuck in an incorrect position. eject can only happen if the sensor (either optical or mechanical senses that a tape is present. The swich might be stuck or the sensor might be blocked or bad. You can open up the unit and try to determine if the sensors are not being blocked by any of the mechanical parts of the unit. You will need the service docs to show you where the components are located. I hope this helps. Shuttle83

Toshiba MD20FP3 not turning on

Is a good thing the main fuse is not open,your problem is in the power supply ,as I understand you have no indication of power(no lights,No clicks)The 5 volts that power the microprocessor might be missing,this 5 volts usually come from a regulator,this regulator should have 12 volts in one side and the 5 volts in the other,the 12 volts come from the secondary of a transformer and it has its own fusible resistor,if the resistor is open is because the regulator is shorted and it need to be replaced.This is a good place to check.Be careful when checking this parts.If you are not too familiar with tv service seek the assistance of a servicer,it should not be too expensive.

Toshiba MD20FP3 Combo does not turn on. Help!

Not unless you have taken the time to learn all the safety issues concerning the HI voltage safety facts, in the repair of electronics? It sounds like your tv has a problem in the sweep/power supply circuits, and since these sets have NO user serviceable parts< its best too leave these types of repairs to a certified electronic technician. Good Luck
