vertical jitter problem (SONY GDM-200PS)
Hi,
I got a used SONY GDM-200PS monitor. It is a really nice 17" monitor. However, it has a vertical jitter problem. The screen on left and right sides are distorted. It looks like: \ / / \ | | \ / / \ \ / / \ The image at the center also has the vertical distortion, but it is not as bad as left or right side. I suspect it may be as simple as a bad Cap. Would anyone enligthen me how to fix it? Thanks a lot in advance! Torgoch |

Hi Wayne,
Thanks for the tips and URLs. I just come back from a trip and read your message. Sorry for the late response. It seems no luck for me, since I bought the complete monitor for 40CAD, and hope to repair it by just replacing some caps. Now the result is out of control. The new CXA2043Q ($36.39) will almost cost another used monitor, and I think that I have only 50% confidence in the success of soldering operation. Anyway, your message may save me a lot of time in searching bad caps. Again, many thanks and best wishes. Torgoch (Wayne) wrote in message news:400aecaf.2394553@shawnews...

Torgoch The GDM-200PS is a Sony N3 chassis; most likely failure is CXA2043Q, which results in many deflection-related faults, a common failure in N3 chassis. Requires above average soldering skills to replace without destroying the mainboard traces. You can download the service manual here http://www.geocities.com/monitorss/schematics.html MCM http://www.mcmelectronics.com/ has the IC for $36.39 - best price you are likely to find. Wayne |
