Hi. My Sony Videoscope XBR's Convergence Allignment


I happen to share this same problem. The alignment of the gridlines on the standard convergence panel are completely abnormal, and if I attempt to auto-adjust the TV, it flashes different colors on the sides of the screen , and then turns off the convergence settings.

Turns itself off after being turned on.


Here is what you do:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

LET me know what you find and I will tell you what it means and if possible how to fix it.

More than likely it is a convergence problem. Best way to tell is to unplug the plugs marked red conv, blue conv, and green conv. Careful not to unplug yoke plugs by mistake, and make sure you mark plug and board when disconnecting. If convergence amps are the problem, set should power up with convergence plugs disconnected. Do not leave set playing very long. This is just to verify problem. Your welcome, Russmann.
