Re: Polaroid LCD has Flourescent Lights and a Blurry...
Okay I just got mine to work. All I did was: click menu on my remote control, go to setup, go to the very bottom where it says "Default" and press ok on the remote. Everything went back to the default settings and worked.
If the audio still doesnt work, go to menu, audio tab, down to MTS system and hit right or left on the remote to change the audio setup.

the inverter is what powers the flourescent tube lights (Back Lights) so you can see the screen image. As a LCD panels picture is very very dark it needs the lights behind it for the image to be able to be seen. The inverter is the "power supply" for those backlights.
Your model is a LCD flat panel which doesnt have a lamp. Instead they have a series of flourescent tubes behind the Screen which light the screen. The backlights hardly ever fail its usually the Inverters which fail when you dont have any picture with that model. You can get the inverter board and free technical assistance from www.tvrepairworld.com
Depending which model, this tv may have an inverter master and slave module set. I find best to replace as a pair. These modules feed the flourescent lamps that backlight you lcd screen. more than likely the one failing is on the same side as the spot you are seeing. I always first look at the power supply panel, to be certain that capacitors on this board have not failed or leaked out.

Open the back of the TV. Then turn it on. You should be able to see white light indicating the flourescent lamps are on. Don't touch anything tho because there are high voltages there. If the flourescent light dont come on then it is the board that powers it. If the white lights are on at the back then it is the main picture board. I may add though that the power supply that powers the flourescent lamp has higher failure rate.
This sounds like a diffuser problem. Basically the LCD Panel is defective.
32" LCD TV use about 8 horizontally mounted flourescent bulbs. They use a plastic material that diffuses (spreads) the light from each bulb evenly on the screen. If this Diffusion Material becomes wrinkled it will leave a grey cloudy look on the screen.
It is possible that the LCD Panel Glass is defective buy honestly I would guess the diffuser.
This isn't cheaply repairable and it is better to replace the TV unless you are experinced with Electronics repair. There may be a possibility to pull this material out and replace it with something readily available from Home Depot but I have not tried this before. It is possible to pull this from another LCD TV.
