Generally a blown Lamp. If you see a start up screen when you first turn on the projector then it's a cable issue or you haven't initialized external screen.
The whistling is nothing but noise. You need to open the projector to confirm the source of noise. It can either be mechanical or electronic. Possibility of mechanical noise sources are colour wheel (a 4 colour wheel near the lamp), blower fans & exhaust fans. All these are rotating things. If any one of them is jammed, then so as to try to rotate at full speed creates noise. To reduce mechanical noise it is necessary to service them. Dust is one of the main reason. For electronic noise check SMPS (Switched Mode Power Supply) & lamp ballast (electronic choke).The electronic noise is a high frequency noise generated by such devices. Are you using the projector in dusty envionment?
proable solution the cooling fan is giving problems. the whistling sound most likely is fan rubbing on a wire??? The unit gets over heated and turns off for protection. Good luck
a couple of things could make the tv chassis whistle 1 coud be dry solder joint probably on power capacitors 2 IF your tv has tube the board on the back could be making the noise its to do with the yoke on the way out!
