I posted about my Toshiba (CX32D60) a few months ago when I was going to
attempt a repair. The picture on it went to where people on the screen
were all squatty and cone headed. The general consensus was that it was a
vertical IC problem. I have some time now and have it torn apart. I'm a
rookie and feeling my way around. I've managed to not shock the *** out
of myself and have located the vertical section of the board. I guess I
should be desoldering the IC and the caps in the area. I think I remember
someone saying in a reply post to someone else, that the caps will have
similar numbers. The majority of them in the area are numbered C300
something, and there are others in the area numbered: CD101,
CD10,C823,C821. What looks like the vertical IC is, I guess, IC301 with
the markings of LA783 on top and 4C5 under it. I have had great success
using wick and removed a half a dozen so far. I guess my question is, do I
need to remove and replace all of the caps in the neighborhood or just the
ones in the C300 range, and does the IC probably need replacing? Is it
usually just the caps or both that are bad? Also where does one get the
replacement parts? I went to "Fry's Electronics" and found about one in
ten hooks that had anything on them. I haven't done a real search for a
real electronics store in the area yet. I live in So. California, the LA
airport area. Do people usually buy online or try to find a store? Thank
in advance for any replies and help.



It's probably just the caps, I don't think I've ever replaced the IC in a
Toshiba. IIRC there's only 2 or 3 caps in this circuit, usually they're
red.

I've been looking at caps at various web pages and am going cross-eyed.
What's up with the different color of these caps in question? Is it just a
certain brand using a different color? To replace caps, is there anything
to know other than match the "uf" and the voltage ... and of course, install
them with the polarity correct? I thought I read somewhere about being able
to go, somewhat, "over size" with the voltage ... or did I dream that?
