When I plug in my tv there is a loud squealing noise and the tv won't turn on.
I read on the web that it is a component that is shorted out. Anyone have an idea as to what that component might be and is it something I can replace? I'm pretty handy.

Yes it is the Horizontal Output and a few capacitors and resistor that needs changing. If you are good at desoldering and soldering you could do this. I think on this set its the Q4401, caps C4402, Cr 4402, Check Q4802, C4102, If you just want to try new parts and hope it works then you have to check voltages at different points to fix set. Now it also could be Bad Flyback in this set too. I have seen where you change flyback and horizontal output and c4402 would do it. R4118, R4114

Sounds like the color wheel. It's the only moving part in most DLP's and the bearings can go bad. If it manages to get up to speed the picture may look normal. One temporary solution may be to let it run a few minutes, then turn the set off for 10 minutes, then turn back on. When my color wheel was going bad that would often quieten it down. For the rest of the day, try to leave the set on, especially if you're only going to be away from the TV for short periods. You can turn off your cable or satellite box but leave the set on and you won't have to go through the hassle of trying to quieten down the color wheel until the next cold start. Of course the best solution is to replace the color wheel which even with a rebuilt unit won't be cheap if your warranty is expired.
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.
