Calvin,
I have use generic caps for a long time with no problems. It is possible the new one
you used had an
extended shelf life...
Satisfy your curiosity...try a new cap from a new batch.
I use the $40 Dick Smith ESR meter I bought about 6 years ago....still going strong.

Subject: [Techs] Toshiba TV model CF3060K question UPDATE
Set came in from another repair shop that had
abandoned the repair on it......should have known this
would be trouble :(
Had about 3" of vertical foldover on top and bright
screen with retrace. I found C-447 open 33/250 volt
cap open...this repaired the bright/retrace...then
replaced C-305 2.2/50, C-301 2.2/50 and then had poor
linearity. Checked C-308 and found a
3.3/160??????????? According to tip program...should
have been 220/35.......replaced with 220/35 and set
looks great.
This chassis looks similar to other Toshiba's I have
done in the past and I seem to recall seeing some red
and brown caps in this area....but, none are to be
found......I suspect they were changed at the other
repair shop.......question is....which ones were
originally colored caps.......and should they be
replaced with the original OEM colored caps, or does
it make any difference?
Thank-you for any help :)
******************************************************
I let the set run for several hours yesterday and out
of nowhere, the vertical linearity became unstable.
Starting flickering from normal to stretched at about
2 second intervals. I pulled the "black" C-301 2.2/50
I had installed the day before and checked on sencore
LC76....checked fine for value,leakage, and ESR... I
was reasonably sure some of those caps or possibly all
I had changed were originally "special colored
caps"??????? At any rate...I went out to the bone
yard and found a brown 2.2/50 and soldered 'er in.
Set has been running fine ever since. Is it possible
the original "black" 2.2 I put in was one of those
fluke caps that checks good......but 'aint...(it was
brand new out of the package)...or is there something
to these "colored caps" that Toshiba uses. I guess I
better let this baby burn in for about a week before I
ship 'er....I'm feeling a little jittery about the
repair.
Thanks,
