It seems that your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur.
You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done. It is that sound that gives it away, this is a typical switchmode Power Supply problem.

Hi
It is probably a power supply problem associated with standby circuit. If this circuit is bad the set hardly comes on and fails. This is a task for a technician to trace the fault through the whole power supply.

This is a very common problem in these sets. I would recommend taking it to a certified repair shop. What normally happens is that the x-ray protect transistor starts to "leak" (electricity, not fluids) and shuts the unit down. The repair is not too costly.

connect the aerial to the dvd/vcr/freeview combo, connect a scart from that to the tv, from the scart out socket.
you can then connect the sky from the scart marked tv to either the tv direct or to the combo if it has a second scart.
Note. a scart socket with an arrow going into a box is an input, coming out of the boe is an output and a double arrow is a two way scart.
if you use scart 2 on the tv to connect the combo, the combo will recieve a signal from the tv for recording.

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 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.

All I can say is that the black box appears when the closed captions are on and set to TEXT. This is normal. Turning off the closed captions should make the black box go away. If the closed captions are somehow turning themselves back on, there may be an issue with the microprocessor in your TV.

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
