65 in wd-65638 looks like dirt inside the scrin

Use Osram or Phillips bulbs

Check for blocked air flow

Always allow TV to complete cool down with plug in wall

Check/Replace ballast

if the power LED is flashing green then there is a circuit or board that either has a blown fuse or relay. if it comes on solid red when you turn on the television then the Lamp inside is burned out and needs replaced. Before you spend all the money that changing the bulb would cost i would invest that money in a good LED Smart TV instead. Sometimes you just gotta let that old technology go away.

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.

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.)

check cables in the back properly hooked - audio to audio and video to video. colour code may help.
