After a while these tv's vertical or horizontal circuts go bad eventually leaving a line up and down or across which sometimes can be hard to see or not hard to see , in the flyback circut it is common for the solder connections to get heated up and become disconnected, so try resoldering any bad solder, if that don't work the components will need to be tested and the flyback high voltage transformer will need to be tested for connectivity(after voltage discharge) if this don't work then the tube or the crt board is failing, either way some knowledge of tv repair will be required to determine the true cause and source of the problem.

You need to move further south if it is frozen. It's cold up north :-)
If you've pulled the power from this tv (power cycled it) and it still has this problem ... frozen with no picture and no sound. How a screen can be frozen with no picture, I'm not sure. But it sounds like you are going to be on your way to the repair shop. Or to buy a new tv.
If I couldn't see and couldn't hear, how would I know you were even here?
Hi, although I have all sony tvs in my house, every room brand new, when there broke there like a opened bottle of wine ,FLAT, no good!! A 27 is so cheap its worth buying a new one. UNLESS you live where you have friends that fix them on the side. I do and if you ever get to seethe inside of the tv you will wonder what your paying for there is only a few parts in them now and my friend chks them with a machine in 10 minutes if it is worth fixing he has the parts on the shelf and it must be under 100 or its going in the barrel. I have had 1 fixed 10 minutes still good other 1 he threw it out. That's all I can do for you from here, sorry, good luck, Frankie
Does anyone know where can I buy a screen for a 27" LCD Insignia TV. Model is NS-27LCD? My screen creaked. I checked out e-bay and have not found a broken TV with a good screen. Does anyone know where I can buy a screen at. Thank you all for you time. JC
IF THIS IS A LCD---TURN ON, AS NORMAL AND HAVE A SIGNAL INPUT,,CABLE ,SATELLITE CONNECTED TO THE ANTENNA INPUT .MAKE SURE YOU HEAR SOUND.. HOLD A LIGHT (THE BRIGHTER THE BETTER) IN FRONT OF THE THE SCREEN ('BOUT 3 INCHES)--IF YOU SEE A DIM PICTURE---BAD SCREEN AND THATS BIG BUCKS---IF STILL NO PICTURE--CIRCUIT BOARDS AND USUALLY THATS BIG BUCKS!! GOOD LUCK
This problem sounds like a short inside the picture tube itself unless a driver transistor failed that drives the red gun in the CRT. You may have to take it to an authorized repair facility if the picture tube is still in warranty.
