I need to replace a 2.2 mfd 160 V cap, but I don't know which type
of capacitor,(electrolytic, tant, mica, poly... etc.) it is, and I haven't
opened the set yet because although it has a problem, it is still watchable
and I'd like to find out the type of cap so I can buy it before hand and
swap it at the same time I first open it up for service as not to
inconvenience the customer, (who happens to be my ex, and you KNOW how
touchy that situation can be right? She's my ex for a very good reason
vbg) And obviously, seeing as who it is, you know it's going to be a
"government job" Know what I mean?

HOw in the world can you know that it's a specific capacitor without
having opened the tv set?

Simple, it's a common, well documented malady with this particular
model. The set displays the exact same condition described by the numerous
sources of common technical problems with certain TV models. In the
description of the capacitor however, the various sources of this
information fail to provide specific information about exactly what type the
capacitor is. An educated guess would be that it is canned electrolytic, but
there is also the possibility that they have used a tantalum cap in this
circuit. It would make a difference.

Either you're guessing at what it might be, or you've done the old
"I took it to a repairman, but they wanted $200 to repair it, so I'm
going to do it myself. But I need to know, what's a capacitor?".

You couldn't be further from the truth. I am a disabled, (and
obviously semi-retired because of it) former R&D engineering tech and I also
had a repair business myself. Because of the limitations posed by my
disability, I had to quit and only work on personal and "friends" equipment.
Most of my test equipment and documentation was either stolen, given away,
or lost since then.

Anyone who really had an idea would be able to make a very good guess
on what type of capacitor.

You're absolutely right Michael, but as I explained above, a guess
isn't always right, and I was hoping someone would have the information that
would cinch it so I could do the repair in one visit. I have a difficult
time getting around, and wouldn't be doing this repair at all if it weren't
for the fact that my daughter lives with her mother and asked me if I would
do this repair for her. I figure I'd at least try to do this while I still
can. BTW, the RCA transistor I requested info on in another post is for my
own set.
