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.

He owes you $200 to get the set back now, tell him it is $400 for the full job.

Samsungs' service menus are not very friendly, and he probably reset it to pre-alignment facotry default data. He shouldn't have been in there. He pays, either that or take your parts out and send him on his way. If you are an ASC you should have the info to do a full alignment, if an independent you better have some time on your hands.

Take his money and let him go figure out what he screwed up. The circuit has been repaired.

On any three CRT based RPTV that has self focus, magic focus, flash focus or anything of the sort, there are sensors around the screen. As such, geometry settings are very critical. If he lost those, even if you are not seeing any major geometry problems, you might have to buy the overlay to get it right.
