There are a number of reasons this could happen and unfortunately not much that you can solve. If you have a backlight control in the menu you could try turning this down to see if the problem is reduced or cleared. This won't help you but the info may help a tech.

Use Osram or Phillips bulbs Check for blocked air flow Always allow TV to complete cool down with plug in wall Check/Replace ballast

Its not dirt, the light engine is failing and this part is not cheap.

There are multiple fans and a high speed light device and a ballast in that television. All could be causing this.

Possibly replacement lamp is wrong power, size, type, etc., or may be defective. Try another lamp. Also, clean and vacuum cooling fans and filters. One fan is squirrel cage type, the other is a pancake type. Lubricate each fan with a tiny drop of Z-Max or other light oil on each motor bearing. Regards.

Replace lamp. Regards.

that squealing noise is probably the color wheel & if it is available it is as an assembly. will need to contact local servicer for est.

It sounds like you have a separation issue. The material that the screen is made out of is layered on top of each other. What happens is it separates and causes the distortion/discoloration. When you press on it you are actually pushing it back together like a fly paper that doesn't want to stick anymore. There is not a fix for this other than a new tv.

Press menu and input on front of TV for 5 seconds. Green light will flash two digit code 5 times. '12' is no error(no problem.)

Likely a bad lamp or a color wheel not starting.
