woohoo! success.
ordered 2 new convergence ICs thursday from east coast transistor... ($8.95
each on ebay) look like OEM (listed as sanyo) and after a LOT of sweating
over the board laying on my stomach because i was afraid to pull the fat red
flyback cable... (it seemed like it was soldered or something in there
because i pulled HARD on it and it didn't budge).

i managed to get the 2 chips desoldered off the board and the new chips back
on... new heat sink compound and a pretty decent solder job if i don't say
so myself. (first time i've done any PCB/IC work). put it all back together
and BAM! (not literally) but BAM... perfect picture.. only maybe 1/8 inch
out of convergence.. ran the auto focus and it was dead on!

really excited since i only paid $300 for the tv and about $30 for the chips
(with next day shipping).

thanks everyone for the help!

this is my first post here but hopefully someone can point me in the right
direction or help out.

i just recently picked up a used sony KP53XBR200 53 inch rear projection
tv.
it's visibly in very good condition and i tested it on-site and it seemed
to
work without noticing any issues. we loaded as carefully as possible
without
slamming it around, etc, into one of those home depot rental trucks and
stapped down very tightly for the 20 mile drive home.. not a very bumpy
trip
at all.

i know these tvs are delicate so i did my best to be very careful.

we got it home and fired it up... the red gun is way out of alignment..
probably about 2-3 inches off. I opened up the tv and nothing is visibly
loose, etc. I cleaned out some cobwebs, cleaned the mirror, gun lenses and
inside of the screen (filthy!) and buttoned it all back up.

this tv has an 'auto focus' for convergence but no manual convergence i
could find. when i run the auto convergence it moves the red signal closer
to the center + but never converges it fully. the numerous times i've run
it
i've gotten the following error codes... E12R, E17R, and E13R

after about 30 minutes of being left on last night on the red image seemed
to have some horizontal jitter in it. almost like some electronic noise or
interference and was wavering from 1-3 inches off convergence to the
right.

strangely when i turned the tv off.. then back on again.. the picture was
clear as a bell with no convergence issues.

i left it on overnight and when i woke up it was still fine after about
6-8
hours. I turned it
off and went out for the day... came home about 4 hrs later and it's back
to
a convergence
issue again.

i kept cycling power with no change and then out of nowhere the image
converged itself. an hour or so later.. while watching the TV the
convergence went off without warning and cycling power didn't seem to have
any effect.

i'm assuming convergence on this isn't a matter of physical positioning of
the guns but more a circuit board controlled thing. maybe the red board
needs replacing?

this is a longshot but does anyone have a service manual for this tv or an
idea of what could be causing the issue and what it will cost to have
fixed?
also.. what should i look for when calling around for a service technician
if this is not something I can fix myself (i do have some technical
ability
and not adverse to getting in there and swapping parts if possible.)

thanks!
keith.
