Hello,

I accidentally locked my 20 inch HiSense LCD TV (Model No. TC2020) with my RCA universal remote control and I cannot unlock it. I can turn the TV on and off, but all I get is a blue bar that says "LOCKED" and I have no idea how this happened, or what to do in order to unlock it. The model number of my RCA remote is RCR412B.

Any help would be very much appreciated!

Sorry, I tried to pull up that TV in a couple of my remote editors databases. Hisense is not even listed as a brand. I was hoping to find a discrete command for lock or a service menu command. No luck. How old is the TV and where was it purchased?
What brand code did you enter into the RCA to control the Hisense?

CCD, other brands that use the same codeset as the Hisense are:

Apex, those that don't respond to the toshiba tv code
Norcent
SVA

Ok, well there is your answer. SVA is what you want to program your remote for. There is a Vchip button and many other button that I cannot identify. You probably found your TV via a code search so finding it again with a non-functioning TV may be tough. Plug in the SVA code and start pushing buttons. I hope this helps.

I bought the TV at Best Buy as an "open box" item without a remote or a manual about 9 months ago. I also bought an RCA universal remote to go with it. I used the "auto search" method to program the remote and it found a code on its own.

I have a Hisense TV TL3220. I just bought a RadioShack 4-in-one but the code provided does not work (0478) . Does anyone knows which code I need to use?

If not , which Universal remote control is compatible with the TL3220 model?

Thank you !

Did you try the brands listed above?
BTW... This is probably a better forum for what you need.

Have you tried the SVA code?

Yeah , I tried all the codes listed above already. The remote that came with this TV does not work. very anoying .

I listed the model number of my HiSense TV incorrectly (sorry). The correct model number is TL2020. My problem was not that I couldn't get my RCA universal remote to program for the TV. I did that successfully and it still works. My problem is that the actual HiSense remote has a button on it labeled "lock" and that allows the user to lock the tv so that it cannot be watched (although it can still be turned on and off, just showing a bar that says "locked" when it is on). I finally called HiSense and was told that the ONLY way to unlock a HiSense TV is with an actual HiSense remote. This seems like a ludicrous feature to me!! I did order a HiSense remote and will simply have to wait until I receive it to watch the TV.

Thanks for trying!

Sorry I could not help. There is no lock button in any of my databases. Are you sure there is not a button labeled something different on the RCA that will lock/unlock? Was it locked since you got it? I thought it got locked after you programmed the remote. That would mean you could unlock it.

Yes, it did get locked after I programmed the RCA remote. I have been using the TV with the RCA remote for 8 or 9 months with no problems. There is not a button on the RCA remote for locking/unlocking. The people at Hisense told me I probably hit a series of buttons which caused it to lock. If I knew what series that was, I could probably unlock it with the RCA remote, but unfortunatey, I do not.

If you have a learning remote, teach the "Unlock" code to your learning remote then you can return the HiSense remote after you teach the code to your own. However the shipping costs may make this not worthwhile.

Man, that shows a ton of ethics and class.

It's pretty silly to have to pay for a new remote for what amounts to probably pushing one button once and only one time.


I had a similar experience a couple months ago while visiting my mother. I was rewiring my mothers system after a cable installer had installed a new cable box. My 80 year old technically challenged mother needed things a little more simplified for her to work the system.

Anyway after I rewired her system I realized that at some time some how the PIP had turned on. Well my mother no longer has her original remote for her TV and had been using only her cable remote to turn on and off the TV. Since there are no menu controls on her Sony TV beyond the basic there was nothing to control PIP. She had several remotes, cable box, VCR, DVD, an old universal remote that was programmed for an old Mitsubishi TV but not her Sony and no longer any programming codes around for it. So after about an hour of trying every button on every remote she had I realized nothing she had was going to turn off the PIP. I probably had about half a dozen or more remotes that would have worked for this at my home (a 5 hours drive away).

So I ended up going to the closest store to her for a remote a Circuit City and paying $35+ just to turn off her PIP which she would never ever use for any reason herself. It was not until I returned home that I thought I should had returned the remote and gotten my $35+ back. I am sure that remote will probably just sit in her drawer and that the remote codes will be lost before there is ever any need for it again.
