You are going to need an original remote for that set.

Hello
It will be very difficult to unlock RCA TVs without its orginal remote control handset. Anyway just try this, This is the actual proceedings to unlock the RCA TV with its original remote. If you fail to do this with your present universal remote control, just buy an new original one from RCA Authorised Service Center at tyour town, or just borrow it from any of your friends or relatives; just to unlock your set. After unlock, you can use the universal remote control. Just follow the proceedings given below. One amoung them must unlock your RCA TV.

Most RCA TV sets use a four digit code to control the v-chip. The code reset is different depending on the model. Try each number until you find the one that works for you.

1. Hold down the MENU button on the remote and VOLUME DOWN button on the TV it's self at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
2. Hold down the 0 (zero) button on the remote and the VOLUME DOWN button on the TV itself at the same time for at least 4 seconds. The set won't say so, but the lock will be unlocked
3. Hold down the MENU button on the front of the TV and the TV button on the remote at the same time for at least 4 seconds. 4- Hold down GO BACK button on the remote and MENU button on the front of the TV at the same time for at least 4 seconds.

Hold down EJECT button on the front of the TV set and the MENU button on the remote at the same time for at least 4 seconds. Depending on the model, one of the methods should unlock the V-chip. Now, if desired, you can change the settings on the V-chip by going to the MENU and going to PARENTAL CONTROLS, or on some sets, going to MENU and then going to TV SETUP, then to V-CHIP SET.
OK.

My sound goes out on one station and none of the others. The only to get the sound back is to shut the TV off and then turn it back on. I suspect something was pressed on the remote, but I can't figure it out.

Try website like Remotes.com.U can buy the original remote or very colse to the original remote.

Insignia will tell you that you MUST have original remote to unlock. You press and hold Display button for 5 or 10 seconds. My problem is Best Buy tried to repair mine 3 times and one of those times replaced a board inside and original remote will note work and they will make no attempt to help me figure out what is inside. Mine has been locked for over a year. Locked by accident with universal remove.

1. Locate second power switch on back hidden below curve, left side if facing front of TV.
2. Turn TV on using this power switch while holding in MENU button on right side of TV.
3. This is reset the Lock feature!!

Better off getting the original remote.
I never seen a universal remote that really did a universal job.

The cheapest place I found a remote for you is Remotes.com
They have one for $27.94
Just put in "NSLCD37" has the search.

I hope I answered your question. Please rate me. :)

I CAN HELP! After my having my Insignia NS-20LCD picture locked for over a year because no one could give me a way to unlock it, a co-worker found the secret!!

When facing the back of the TV, there is another on/off switch on the back on the right side just under the curve (very difficult to see). I didn't even know it was there.

Once you locate, turn the set on using that switch while you hold in the "menu" button on the right side (when facing the front) of the TV. This will reset the television and unlock the screen!

I found this site:

which lists the universal remote RCA (model RCU807) code as 135

I just bought one of these TV's last night.

Good luck.
