Forgot v-chip code

No,way to reset secret codes.Try Mitsubishi wbsite,talk to Mitsubishi customer seviced,might get some diffrent insight.

Bypassing the V-Chip Lock on most Mitsubishi sets:
Mitsubishi sets use a four-digit passcode that is required to view a V-Chip locked program, view the locked TV, cancel the lock, or enter the V-Chip lock menus.
If you don't have the passcode, it is easy to bypass. This is neccessary if you forgot the code, purchased the set used, or if you simply don't feel like searching through your files to find it.

To bypass the V-chip: You can view the locked shows by pressing the number 9 and QV buttons on the remote at the same time, whenever your passcode is requested. This process temporarily unlocks the TV.

To reset the code: When you use the button combination 9 and QV while entering the V-Chip Lock menu, this process deletes your old passcode and prompts you to enter a new passcode.
Good luck, and let us know how you made out with this TV set.

I got a jvc tv-13142 at a pawn shop but some of the channel is blocked and i need a vchip code to unlock it i try all zeros and it show error how do i reset code

TO UNLOCK ENTER CODE 1234.

Turn the volume down to 0 then change to a blocked channel. (where it asks for v-chip password) Next, on the TV, not from the remote, hold the volume down button, and hold the '0' key on the remote for between 2-10 seconds... the screen should unlock and you should have no V-Chip restrictions.

I cannot find any way to reset it. You might contact the manufacturer.

What is your problem ?

i don't remeber ,the tv program code. at the sharp tv.
