Model # HC-P4252W, Chassis # P59A, customer was into the service menu.
He said he psessed a button, while in the service menu, then a single
crosshatch came up with factory
data, then it wouldn't work right after. Now, after repairing the unit
for bad convergence IC's,
& open resistors, when pressing "self focus", it stops, right after
it starts, & says "check
factory data". How do I undo this! Also, now the "saved" convergence
adjustment in the service menu, "drift". After tv is off a while, the
left, & right sides need to re adjusted manually again. Dani.
