My Soyo SYTPT3218AB LCD HDTV gets intermittent broadcast reception. I've tried numerous antennas and locations. The TV will play well on a certain station for days and then suddenly have troubles receiving and holding the signal. The weather does not seem to be a factor. Where do I start looking to solve this problem? Also, I have a TV converter box that gets all the stations and is very stable. Location is not a factor.

I'm trying to fix a Soyo LCD TV that was given to me.
It comes on, sometimes, and then plays awhile and shuts down.
I found 6 bulging caps and decided to replace all 10 of them.
I made the mistake of ordering two Panasonic 220uf 25v caps,
that are not low ESR. Manufacturer Part #: EEU-EB1E221S.
I think I should have gotten Manufacturer Part #: EEU-FM1E221,
which has a lower ESR. Can I get by with these, or should I order the
FM caps? Tha data sheets are attached.
I was smart enough however, to oder the right ones for all the rest....
