I purchased a tv at a pawm shop and vchip is activated

Hit the Menu button on the TV. 2. 'INPUT SECRET No.' should appear. 3. Press and hold both VOL (+) and CH DOWN (9) on the TV set simultaneously until the message 'INPUT SECRET No.' disappears. 4. The vchip settings should be disabled now and the Parental controls menu should be presented, 'disable' Status if need be.

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

Try generic codes like 0000, 9999, 1234

I HAVE A SANSUI TV MODEL DTV2798 AND THE VCHIP IS ACTIVATED. I DO NOT HAVE THE CODE. DOES ANYONE KNOW HOW TO FIX THIS ISSUE?

Hello there, I would unplug the unit and allow it to be off for over 24 hours and that should cause the memory to be gone, including the Vchip code where the TV set goes back to the manufacture's settings.
Its always best to write down codes for future refer.

1. Hit the Menu button on the TV. 2. 'INPUT SECRET No.' should appear. 3. Press and hold both VOL (+) and CH DOWN on the TV set simultaneously until the message 'INPUT SECRET No.' disappears. 4. The vchip settings should be disabled now and the Parental controls menu should be presented, 'disable' Status if need be

Remember do it on the tv not the remote

Most likely, the tape has been coded with a "R" rating or something that the Vchip in the TV/VCR is blocking due to a prior ratings lock. Look up model or call service and find master reset code, like 0000 or similiar to get VCR vchip back to factory default of no locks.

cant figure out the code.

Here's your  answer - Hold the down volume control on the TV. Then press the remote # 0. This will bring up the reset password menu. Then reset the password. We need a kid to solve are problems. FWL 

Call the customer service number on the back of the set.
