Had a repairman in and he did exactly this and for less than $90 total we have our 36" Toshiba TV working in our bedroom again. It's gonna make the Christmas bills a little easier to pay.

Toshiba 27af45 repeatedly turns itself off. Sometimes (usually) every few minutes, other times will stay on for hours. Works perfectly otherwise.

The fact that the television stays on for hours and other times turns in five minutes shows that your problem is intermitent .A defective component in the power supply is probaly causing the B plus voltage to go up.The TV can also have a dry joint which looks more likley i am curtain if you gave the TV a firm tap to the side when it come off it would come on back. Try it .

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.
