Question about Dell UltraScan P1110 21" CRT Monitor
Last week, my GDM500PS got the deflection problem. As most people suggested in the Web, I replaced the IC007 (CXA2043Q). When I powered up the monitor, it is OK initially. However, after 5 minutes or less, the red color is missing and the green color changed to greenish yellow. At first glance, the red gun is dead. But the white color is still white (that is, RGB is OK). It seems to me that the new chip causes the malfunction or wrong color processing of the monitor. Do I need to use Sony DAS software to tune the monitor or is there any simple method to adjust it? Thanks.
Sounds like another IC has failed. there is one in this chassis (21N3) that causes similar problems. but i cannot recall what it is or it's IC designation, but i do beleive it is on A board
