Depending on the model of the TV some projection TVs have a soldering problem. There could be a short on the Main Power Supply. It maybe necessary for a professional to do this work if you don't have the tools or if is not soldering issue.
Power supply board have problems,capacitors are leaking,and dying,most of them will bulges up,or rust form on the board.U know how to solders,have soldering iron,and solders?Tries these websites Tv repair World.com,Tvrepairkits.com to buy a power kits they put together for many models of DLP tvs,for these power problems.
100uf,35volt capacitor is bad in the power supply. Take the back off. Follow the power cord to the main board. Straight in front of where the power cord goes into the board you will see a heat sink (tall metal) that has a transistor attached to it. Right next to the transistor will be a small capacitor about the diameter of a #2 pencil and about a 1\2 inch tall. There are only a couple of capacitors in this spot on the board, just make sure you replace the one that is marked 100uf, 50volt. Replace this capacitor and the sets will work. Let me know if this works, please. If it doesn't work, let me know the sets' model # and I'm sure I can assist you further. Have a great day!!!
check the curcuit board where the power supply is sometimes these sets get so hot the solder melts causing short curcuits,be very carefull as tvs can hold high voltage for many years and should be discharged first,there may be signs or arcing near power supply hope this helps...
