My Tv screen dosen't fill the whole srceen

Just on a movie or even watching tv???? If you have the original remote, usually there is a ratio button on it you can push......If theres not, go into the menu and go under video and look for the different ratio (size) of the picture and try one of them......If you still can't figure it out and dont have your manual, you can always "google" your tv and model number and download or at least look at the manual online.....good luck....

On pic no sound blue srceen when turned on

NORMAL OPERATION. Blue screen is a volume cutoff feature when there is no signal. Turn blue screen off in the menu if you want sound when there is no signal. Another option cycle through the input sources until one is found if there are some attached and working.

Poloroid 32" flat screen

Yep! If under the 1 year warranty get it in right away. If out of warranty then it's possibly a power supply issue. Probably a $100 to 200 dollar repair.

I Just connect My pc via 15 pin RGB cable to LG 32R50xx lcd tv,it show the picture but no sound. Than i connect the audio cable to the tv use 3.5mm j. it only has sound when I use input and select AV3 but...

You probably need a audio cable that runs from the pc audio out to the TV audio in. Radio shack has them so do a lot of hardware store and best buy.
