27" JVC Model AV-27920

[Comteck]

I've got a 27" JVC TV. The TV works ok, but there is about an inch of
space on the left hand side of the screen that does not display the
picture. It looks like the screen has moved slightly to the right.
Does anyone have any ideas where the problem might be?

Any help would be appreciated. Thanks!

Could be a fault developing, or it could just need adjusting. the control
will labeled h-phase, or h position (or have a picture of a square
overlapping the side of another square) and if you're lucky it'll be
accessible from outside the TV - possibly using a philips head
screw-driver in the apropriattely labeled hole..

Bye.

If you are smart you will keep your screwdriver out of the set. There are
no controls in the set. All is controlled through the service menu. The set
needs service by a tech with the right experience and access to the service
literature. There may or may not be a phase adjustment, but if there is and
it needs adjustment it is likely that either lots more adjustments are off
if the EEPROM is corrupt, and/or there is a problem causing the shift that
needs to be fixed. Likely the latter.

Unless the TV is at least 15 years old, odds of finding a horizontal
position control are virtually nil. And it's almost certainly
developed a problem. Making a setting adjustment may mask it
for a while, but it will almost certainly get worse. It's
generally cheaper to fix problems when they develop.

Since that set is completely digitally controlled for all adjustments,
it is highly unlikely any adjustment is going to fix the problem. You
have a parts failure that needs to be repaired. Could be in either the
h-deflection or video h-phase circuit.

Although possible, the eeprom could have become corrupted, in which
case the full chassis alignment will need performed after replacement
per the service manual.

Time to take it into a JVC experienced shop that has the service manual
and equipment on hand in order to complete a diagnosis and repair.
