I am trying repaire my LCD TV Westinghouse LTV-32W3. I purchased it 1
1/2 year ago - it worked OK for about 1 year. After warranty expired
it works OK for about hour, after 1 hour the following symptoms
appeared:

The TV on the left is a good one, on the right Westinghouse LTV-32W3

I come to conclusion that some parts in the TV are getting too hot. To
test my theory I removed TV's back cover to allow better air
circulation - now TV is working without problem. What I want to do is
to 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:

here electonic parts with metal case removed:

I guess the metal case is to prevent electromagnetic transmition - can
I make more holes in a metal case without causing electromagnetic
interferrence?

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 power
this fan?

Thanks,

You can purchase a 120V AC fan at an electrical store, but make sure it not
too fast or you will hear it. Most computer fans are 12V and will work with
just about any 12V converter that you laying around, or you can get one at
an electronics stores.
