My Mitsubishi cs 31303 has a password code on it. One of the kids did this accidentally years ago and we've never known the code. So, we press QV 9 to override the code. Has served us well over the years. Well the remote just died so now we can't do QV 9. Is there a way to reset the TV so there is no code?

on the A/V PCB . Check C206 33 UFD 16 V off pin 17 of IC201 on the A/V PCB. Check C207 47 UFD 16 V on the A/V PCB. Check C211 47 UFD 16 V on the A/V PCB.

I've learned from a Mitsu tech that there is indeed NO easy (nor logical & user-friendly) way to UN-memorize a QV channel.

However there IS a work-around to accomplish that so that the QV will revert back to its Factory Setting of "Last Channel Recall."

Using the Mitsu remote control:

1. Poke the Menu button.
2. On the Menu, select the "Add/Delete Channels."
3. Select the Antenna (A or B or whichever) and select the channel which was memorized in QV.
4. When that memorized channel number appears, select "Delete."
5. Poke the Menu button again to exit.

The QV memorized channel number is now gone, restoring the QV function to "Last Channel Recall."

NOTE: If that particular deleted memorized channel was also included among the SQV (Super Quick View) channels, it can then be added back into SQV using the Menu and SQV option.

Hope the above helps those who have encountered the same issue.

bad regulator or high voltage circuit. also some newer sets will shut down if the vertical drive ic blows,because damage to the tube will result from a horizontal line.
