Went to turn on tv and made high pitch noise like a jet engine. Made this noise a couple times and heard a fan kick on then power went off and red light came on.


Colorwheel eeds replacement most likley it could also be a fan but I would assume its the colorwheel especially if it was real highpitched sort of squealing sound. You can get the colorwheel and free tech assistance from the guys over at www.tvrepairworld.com

Check the horizontal output section circuit. It sounds that the LOT {Line Output Transformer} has damaged.

High pitch noise from the projector and is not from the fans


it's the colorwheel. if you have an infocus x1a, it is a dlp projector and has a colorwheel and dmd chip instead of 3 lcd panels. the colorwheel spins to allow the lamp to stike. it should make a slight high-pitched squeal. if it's too loud, the motor is shot and needs replacing.

RCA Model f27650 High pitch squeal


the high pitch squeal indicates shorted component/s. the transformer goes hot co'z its being overloaded by the shorted component, it too could be the one creating the squeal!!

if you have experience with electronic troubleshooting, try to test some of the components particularly on the secondary part of the transformer.
Be careful and make sure the TV set is unplugged.
test for shorted diodes and transistors, if you're in doubt of your readings try to desoldering one leg of the diode then proceed with the testing/measuring. replace any of the bad components you find exactly with same part number or replacements with the same rating.

spend more time on it resoldering some other cold soldered components.

My set has deveolped an intermittent high pitch squeal.


It always nice when the high-voltage circuit gives you fair warning of impending doom. Have the high-voltage (flyback) transformer replaced now before it fails catastrophically and wipes out other stuff with it. There are other things that could make noise too, same advice applies to them.
Hope ya fix it!
