Post by: fargen on July 05, 2008, 05:31:06 pm

heya, I have a 2914f in a target terror and its going dim. The tube tests ok but I heard the flybacks were not great with this model. Does anyone know anything about cap functions on this board to try first to improve pic? or any other ideas? thanx sbm

generally, an IHVT (flyback)  either works or it doesn't.
not much of a grey area there ......

Flybacks haven't given me any problems, and I know of several cabinets with this, the DF (completely flat) variant, or the 34" DF model.  There is side squishing, but that isn't likely related.

I have known the ACL to be problematic, however.  It may be engaging too soon, especially on smallish signals.  You can go into service mode (hold up button as you power the device) and adjust the ACL control upwards.  Be aware that this may also compromise the ability to prevent phosphor damage if you feed it a huge signal with contrast cranked, so don't go nuts.  Be sure to note all original service mode settings, as always, because there's no way to "restore" them.

heya, just for update...I capped this monitor with a cap kit I got from zanen. Picture came back just like new. The zanen kit was short two or three large caps and also noticed one chassis had one cap running in one direction and the other was running as stated on the board. So please pay attention on this chassis. I will post later the caps missing and the cap that was backwards in one.
