I am trying repaire my LCD TV Westinghouse LTV-32W3. I purchased it 11/2 year ago - it worked OK for about 1 year. After warranty expiredit works OK for about hour, after 1 hour the following symptomsappeared: TV on the left is a good one, on the right Westinghouse LTV-32W3I come to conclusion that some parts in the TV are getting too hot. Totest my theory I removed TV's back cover to allow better aircirculation - now TV is working without problem. What I want to do isto install small fan to make a better cooling.I am not a TV technician, so here are my questions:electronics parts that are getting hot are enclosed in a metal case: electonic parts with metal case removed: guess the metal case is to prevent electromagnetic transmition - canI make more holes in a metal case without causing electromagneticinterferrence?I plan to put inside a small fan, similar to one used in computers -can you recommend one?Can you recommend simply converter from 110 AC to 5V(?) DC to powerthis fan?Thanks,Zalek
