Re: 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.

Can't turn on/off using either switch on front or remote. was plugged into outlet on cable set-top box. perhaps something was fried by sudden power outage.

In that case if ther is no power you better check first the power in the outlet they have.Then check the continuity of AC cord of the TV.If they are good,check the fuse,located inside at the power supply section near the AC supply voltage input.Replace same value of fuse if busted.Then try to turn on again..Try this procedure,hope will it help you..Thanks..

Hi My toshiba telly has suddenly died. It wont turn on or lights or anything, I have checked the fuse in the plug and that is about it

The Toshiba were well known for vertical issues and sometimes power supply problems, but in general are worth fixing. I suggest a technician at this point in order to narrow than the cause with an estimate in mind.

I have the Toshiba TV/DVD Combo less than 3 years old

check thje following
the power reaching your switch via a fuse and power out of the switch, when switched on.
if the power is leaving the switch okay then check the power supply components
semi conductors, for leaks and shoots, zener diodes, and capacitors for variations and change of values especially electrolitic capaciturs. if you get a high voltage of 85 and above going to the transistor near the transformer, then check your line trasistor.

V-chip code forgotten

I found this to work on my Toshiba TV/VHS combo MV19M4 after trying others suggestions that had worked on similar models but nothing worked on mine. Maybe it will work for yours. Follow these steps:

1: Unplug the TV for 1 minute then plug it back in.
2: In the menu select "TV Set Up".
3: Move the blinking block to beside "V-CHIP Set" BUT DO NOT SELECT IT.
4: Hold in the number 1 button on the remote.
5: Hold in the volume down button on the TV.

Your TV will turn off. Give it a few seconds to reset itself and then turn it back on and you will have to completely reprogram your settings. When you go to the V-CHIP settings it will ask for your new code.

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
