Samsung SyncMaster 950p 'ghost' problem-Link with pics...
Hi, another one with a problem...
I'm not sure if it is the same problem as others had about ghosts on the screen. Anyway, I'll give you the link to the pics and the story below.... http://www3.sympatico.ca/sbmel/ghost1.jpg http://www3.sympatico.ca/sbmel/ghost2.jpg Typical tests we Transfered the monitor to 3 other pcs with different video cards. No magnetic fields presents Different video cables. Changes in the menu of the monitor, then reset back to factory settings... This problem does not appear in Dos or while loading Windows. It starts at the logon screen. Changing screen resolution or refresh rate have a positive effect in restoring the screen but not always. I then change again until it works. Sometimes it will come back a few minutes later. After about 15 to 30 minutes of working fine, if I don't change the resolution or refresh, it will work with no problems until I turn it off. I took it to an autorized Samsung repair shop. Told me that this a major problem and since they have problems with backordered parts, the best thing is to change the entire circuit board. Usually things go bad as they heat. In my case ,it's the reverse..... Are they right or is it some typical cold solder or capacitor? Any info is appreciated. Many thanks! Stephen |
