This is a common fault on Polaroid LCD, first ensure that the problem is not related to the input channel chosen.
Swap inputs and ensure you have same problem on all inputs, eventually using different cables.

If you get sound an no picture on a Polaroid LCD, that is a defective video processo (FLI8125 (Genesis Microchip) , and that is usually fixed replacing the whole digital board (mainboard, about $75, see LCD Controller ) , as the part is considered not serviceable by Polaroid.

Try calling Polaroid, and insist on the fact that you did not do anything to cause the problem.
You may be offered a free replacement, as this is often considered a factory defect.

You have a bad color wheel. It is a very easy fix. Just call the people that handle your warranty and start a warranty claim. Usually they will have a tech in your home within three days to diagnose the problem. Then the tech will call the warranty company and tell them what needsto be done. He will get permission, order the part and usually within a week your set will be serviced and back to it's former glory. I have replaced several color wheels myslf and if you watch the repairman do it. You will know what to do next time. That metallic screeching noise sure can drive you nuts! I felt like I was going tone deaf when I had color wheel issues. Good Luck, and please rate my solution!

Hi
I'm surprised to read the posts submitted here. No-one has asked the make, model or type of television it is!!!
If its a "rear projection" tv it could be the lamps
Can you please supply us with the make and model

Regards

Try pressing the auto button on the edge of the monitor.
If his does not work press the right arrow key until you find a small picture of a speaker and check it does not have a cross through it.
If it does press the select or down arrow key until the cross disappears.

No picture but has sound


The problem can be caused by a bad sustain board (Ysus Zsus) , the popping sound is often caused by a capacitor blowing up.
The TV must be taken apart and tested before eventually replacing sustain boards.
