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,

If it was me, I'd put a small fan in the lower right (viewed from the back)
section pointing towards the side (just below where the power cable
connects) to suck air from the inside. You can get those same style fans in
115 VAC (GOOGLE is your friend) so as not to have to deal with another power
supply. BTW, computer fans are usually 12 V not 5 V.



And should you put a fan in be sure to use a filter. Dust is another
enemy of small electronics.
