SOURCE: PT-43LC14 No Picture, chirping sound when turned on
Begfore calling a servicer, pull the bulb out and check if it is broken. The chirping you hear could be the ballast trying to fire the lamp. If it is blown, make sure you clean the vent filters when replacing it.

This is no solution but a point in a probable direction.
A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

Most DLP projectors have a colour wheel. It's usually hard to get at,
and you may have to actually remove everything including the optical
block from the projector to access it. This wheel turns on a motor just
like a fan, and if it gets dirty it can act up just like a fan.
They are expensive to replace, so you might want to try taking it apart
and cleaning it out. Add a small amount of 3 in 1 oil to the motor if
you can.
