JVC Help Needed...

[[email protected]]

I've a JVC AV-48WP30 projection set on the bench with vertical
stretched just a
little, affecting CNN's scrolling text, that I need to resolve. I'm in
the
sevice menu with choices 1 thru 8 I believe? The values that come up
with choice number 1 are not identified. Where do I find
the vertical size parameter? Not familiar with this service menu, have
done tons of RCA's and other intuitive menu's but not this coded one.
Can you please help me?
Cheers, Steve

Please read the lower note below!!!

NEVER...NEVER...adjust the service menu, unless your'e sure the T.V.
doesn't have an electronic problem...& it DOES!!! Check the small
electrolytics near the vertical IC. Quite unlikely that the service
menu is in need of alignment. Also, you could really fudge up the T.V.,
if you don't know what your'e at! Also, be VERY, VERY carefull not to
totally kill the set by letting light hit the DVI Digital Input
Module!!!


JVC AV-48WP30\IMPORTANT NOTICE BEFORE WORKING ON THIS SET. If you
remove the rear cover while the power cord is live you will destroy all
DVI programming inside the DVI Digital Input Module!\The only way to
get
this programming back into the unit is to send it to JVC that sends it
to Japan\This module is mounted on the rear AV Jack Board and has a
light sensor built in. When light is detected the module does a
complete
reset and erases the EEPROM\1. Prior to disassembly* unplug the power
cord from the AC outlet without fail. 2. Short the SB connector pin 1
and pin 2 of the Digital Input Module.\3. Before the rear panel is
inserted into the cabinet* release the short circuit on the SB
connector. 4. After releasing the short circuit between the SB
connector\do not turn the power on until the rear panel is inserted
into
the cabinet. 5. Negligence in carrying out the above steps may cause
the
inactivation of the TV\\\

Guys guys guys, I'm very much aware of the DVI situation! I'm not even
close to removing the rear panel. I've just replaced the convergence
amps and need to adjust what's been an annoyance since day one. My
client has lived with this prob since new! All I want is the vertical
size parameter...please. I'm a competent tech and I just want to tweak
ever so slightly. As for the caps near the vert out, been there, done
that, thanks.
Cheers, Steve
