    Could you please explain?

  • Fernaas Dec 13, 2007

    The tv turns on and the volume goes up and down without me touching anything. I have tried everything, the only thing I have not yet done is to throw it in the garbage.

    Any clues?

    Same problem, will change to the default Dish network instruction channel and now it turns itself on automatically... volume seems fine for now. Purchased this TV in Nov 2006.

    My tv also is jumping channels and turning itself on and off. I have to turn the entire sysem off via the power surge so that it won't come on in the middle of the night making me think there is someone in my home. This can't be good for the screen.

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 !

I have a Hisense tl 2020 and last night when turned it on I had no sound

Try first leaving the unit unplugged from main for one hour.

This will drain power and reset circuits.

Check also eventual cable connections, receiver box or device connected.

If that does not solve the problem, then there is an internal fault, probably on audio circuits or I/O board.

The sound doesn't come on with the TV.

sounds like a capacitor problem, they sometimes dont work cold but work ok when they are warmed up. i would not recommend anyone unfamiliar with tv repair and its safety procedures open up a tv set because of the lethal voltages present inside, even when unplugged it can hold a charge for months.

It could well be the accumulation of dirt/dust behind the buttons causing them to stick. If you are able to carefully remove the board that the buttons are located on and use a cleaner that will de-grease at the same time. Be sure that everything is dry as can be before re-assembling and then check if the problem persists. If you are not capable of doing this trust a competant technician. Hope this helps.

My Hisense lcd is lock.

This is how I got mine to work after weeks of struggling just trying to find a new remote (hisense is really hard to contact....).
1) Turn the TV ON. unplug the tv while still ON 2) hold down the "menu" button on the side of the TV and plug it back in. keep holding it down. the TV should turn on with the menu popping up. use the Vol <> keys and Channel <> keys to navigate the menu. go to the Vchip menu, and play around. I'm not sure what ultimately worked, but i changed the Vchip password to 1111, turned the reset menu to "on" and played around with the ratings settings (turning most of them to "u"s etc).
I went through this process several times and finally, the black background behind the menu turned to static. I played around with the channels, and the TV was unlocked. I turned the TV off, and then on again, and the channels showed up normally (no static). and it was no longer locked. I had to do the unplug thing several times, and was getting really frustrated looking for an "unlock code" in the manual (it just says press the button on the remote. so it was not really helpful).
But really, once you can just get to that menu you've made some progress, and just keep playing around with it until something works.
Best of luck!!

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. line-gry.gif
