We have a Haier HTF27R11 TV. We tried to put a universial remote on this tv. Now we have a "Blue screen with red padlock in the lower left corner of the tv." We are unable to use the remote or the buttons on the tv. Does anyone know how to fix this problem? Please help, tv was working great before all this happened.
It sounds to me like a child lock function, which is usually what the screen + padlock is on TVs. Usually your original remote would have a button / sequence to unlock the mode. If you still have your original remote, look for a child lock button or refer to your remote manual (and/or TV manual for the child lock feature) to unlock the mode.

You will have to contact the manufacturer to access a service manual. When you do get this manual you will be given an acess code to enter the software. The values in this manual are good starting points, you must decide to tweak these. Caution this may be very time consuming and if you are not careful you will lose the entire program. Are you sure you want to do this.....consider a new tv.......this will save you a lot of headaches....no brag just facts.
I called tech support and they said to hold down the display button (the one that normally pops up the channel that you're on). I tried it and it worked even though none of the buttons got a response. It's definitely worth giving it a try!
