How do i unlock the vcr without a remote - Mitsubishi HS-U448 VCR

This is the child lock and can only be deactivated from the remote control!

Not sure I can help. You might do well to call Samsung 800-SAMSUNG. But I have the codes that should work if you were hooking the Samsung to a Philips set top box or cable box. Perhaps they are the same? (And how lucky are you that you landed this jewel! I love this unit!

Unfortunately if there is no menu option to do that or button on the VCR you will need one of these remote controls

Looks to me like you didn't need a new remote as the old one was working fine, it's just that the VCR remote censor has a fault on it. Or to put it simply it's the vcr that doesn't work, not your remotes.

most vcr's dvd's and recorders have to have the remote..if you have cable or satellite, you can program that remote to run your other equipment under aux. or you can buy a inexpensive universal remote that can be programed to run your equipment.

Cant' get remote buttons to work. No buttons work so can not watch DVD or Tape but can hear sound. Without the TV/VCR button not respondingnit won't switch over.

the only way to unlock without a remote is to remove the back cover and remove the fuse on the power board, if available

if you need a remote control for your unit go to www.partstore.com and purchase a originald remote for your unit.good luck.

Hopefully you still the VCR. Your's is stuck in "CHILDLOCK" mode. To release the lock you have to have the remote and press the DISPLAY for 8 to 10 seconds.

The purpose of the CHILDLOCK is to prevent others from using your VCR. If you want to set the VCR back on Lock you again press the DISPLAY for 8 to 10 seconds.

This solution is from the owner manual for HS-U448, so I figure your model is the same.
