    I have a Hisense TL2020 and is locked up...the original remote stopped working so I bought a "learning" RCA remote, can't tell you how but my daughter must have hit a combination of buttons and the TV is locked up. I've sent e-mails to Hisense support and no response for more than a moth. I've tried all the other remotes I have in the house and nothing works. Any Ideas on how I can get it unlocked?. I tried calling the 800 number posted and it's not a real #

    Yep, I own a TL2020 Hisense LCD TV hooked up to Direct TV Satellite and somehow it locked up. Blank screen with a box at the bottom of the screen that reads: "Locked". I tried unplugging both the TV and the satellite box, but nothing works.

Try turning the main power switch on the back of the tv off.
Then hold the menu button and push that switch back on while still holding the menu button.
Keep holding the menu button until the setup menu pops up.
Next, be sure your input is set correctly(air or cable).
Next, do an auto channel search.

That did it for me. After I shut it off I had to do it one more time but it did the job. A friend of mine gave me the tv for free because nobody he new could figure it out. I took it home, got lucky, and figured it out in about ten minutes.

Hope this works for you. Hisense flat screen has locked - line-gry.gif

It sounds like the DTV remote activated the "Lock" feature of your TV. If you are lucky enough to still have the original remote for the TV all you should need to do is push the "Lock" button to unlock the set.
Unfortuanly, if you don't have the original remote you will need to call and order a new one from the manufacture for about $25. Their number is 800-287-4871

Are there any drivers I can download to help get my hisense model TL2020 tv to be use as a monitor. If so where can I find them , thank you ,,,, JPetrocine of Florida

If it has a VGA connection, hook it to your computer using a VGA cable. If it doesn't have the VGA connection, it can be connected via a S-Video or a Composite or component cable if your PC supports that sort of connection.
Anyway, no driver needed.

Hisense LCD Tl2020

I, also, have the Hisense LCD 1504 and cannot turn it on with the original remote. I have to use the ON button on the side every morning. You have to hold this button in for a while then wait a while and presto, the blue button shows on the front and the picture comes on. If it fails to work the first try, just try try again. It does work for me this way. We had this same experience with the TV in our room at a Hotel where we were on vacation and the TV worked fine when we turned it on using the side ON button. It just takes a while for the picture to appear. Hope this clue will help someone.

To unlock your Tl2020 with a universal remote just go into the menu and select V chip setting. The password from the factory is four zeros (0 0 0 0 ). Once you get in you will the letter "B" nect to everything. Set everything to the letter "U". Then, turn off the television. The set should be unlocked now. Good luck !
