I am having a problem with my Sony KP-53S35 Projection TV. The remote
worked fine up until a couple of months ago. The remote started acting
funny after my wife cleaned the television the next day it was fine and
now a couple of months later it started doing it again and the next day
it was fine. Then it started again later that day and has not been the
same sense. I have done all the usual stuff batteries, multiple remotes
with the right codes everything and anything I could find to help
explain what might be happening. The problem is the remote works if you
put it about 5" to 6" in front of the little plastic window on the TV.
Cleaning this window on the outside and inside did nothing. The chasis
open does nothing either. I did notice that it was quite dusty on what
looks to be the main computer or "mother board" section of the TV. I am
somewhat hesitant to blow air on this area cause the TV works fine with
the exception of the remote. One other thing I remember is the other
day when it quit working and in the morning it started working I was
messing around with the remote about 6" away and gave up. The screen
went black and a popping noise was heard and the remote worked as
normal for a few days. Any information regarding this kind of problem
would be greatly appreciated. I am looking at the remote sensor. But my
lack of knowledge on this subject is keeping me from doing anything
because it seems to work at 6" why not 10" feet?

Help me please
Thanks for any and all replies!
