Kevin,
If it doesn't come in an RCA bag, it is not an exact replacement. There's no 
play on words...exact
replacement, to me anyway, means you ordered the OEM part using the OEM part 
number.
There are many generic knock-offs out there that will have the same number on 
them.
If you want us to understand your post, use the industry standard, 'generic', 
if it is a generic.

To me the 'exact replacement' has the same numbers on it.  In most cases
the OEM gets them from the same manufacturer as the generic parts
supplier does.  I have had good success using the so-called generics and
they are cheaper.

Kevin,
You say "Replaced same with exact replacement "...now, this makes one
think you used OEM...
So, you used a generic...
I suggest using the RCA part number.

It was not an RCA part; it was just a 'generic' D1885.  I just put in a
C5297 and it is working fine...so far.

Kevin,
Did 'exact replacement' come in a SK bag, or with the RCA number....be
sure to use one with the RCA
numbers...

Here is one for you RCA experts out there.  Set came in with shorted
HOT, D1885.  Replaced same with exact replacement that had lighter and
different white printing on the case of the transistor.  Set fired up
with HV and HOT instantly blew.  Replaced with C5297 and set came on
this time with washed out picture with retrace lines and severe
pincushion problem on the sides.  The picture also filled the screen
slowly from the sides, making it appear to have a voltage regulation
problem.  The width would also vary when the screen was adjusted.  Pin
one of the STK measured -40.3 volts, well within specs.  Not a voltage
regulation problem.  Found and replaced the pincushion capacitor, C4407,
a 47nF blue cap that was open and bulged.  All problems go away.
FLABBERGASTED.

Now my question is two fold:  Would this one pincushion cap cause all
these problems including causing the HOT to short?  And could my
original HOT that I installed been a fake?

I have a second RCA set (two in one day), a CTC187CN3 that had a shorted
HOT as well, a BUH517.  I found a bad connection on the same pincushion
cap (this time a 41nF cap).  The customer also complained about having
trouble getting the set to come on, and then when it did, the video
would go off and on.  So far it is working fine on my test bench with a
new BUH517 installed and the bad connection repaired.  Could this same
cap have caused these 3 problems as well?  Thanks for listening.
