By "convergence gone" do you mean you have no convergence or no access to
service or customer convergence menus? If it's no convergence is the
convergence supply running? It has a rather elaborate shutdown circuit that
will detect about any overload. If you have convergence, but can't access it
to adjust, then there is a communication problem to the main micro. When
this set is turned on, the main micro will poll the devices in the set and
if it doesn't find the convergence micro, it will assume it is a direct view
set and not provide the convergence menu options. One thing to check is the
3 pin cable that plugs into the convergence board. I don't remember the
symbol #, but it plugs in near the shielded area of the board and on some
chassis, the connector it plugs into will have 2 slots. 1 for normal
operation and 1 for "test". Make sure it is plugged into the correct
(normal) position. You might want to look at the clock and data lines for
activity.

| Hi All,
| Had this set come in with just a small green convergence error in the
upper
| left corner. I pulled the convergence board back and checked connections
which
| looked good. I hit the connector pin's with solder just in case and had to
| remove the two ribbon cables and one supply connector (orange and white
wires) to
| flip it up.
| Once I put in back in service the convergence was gone. I attached it to a
| chipper checker to initialize the EEPROM, it didn't help. I aslo subbed
out the
| AUX power supply, that didn't work either.
| Any idea's?
