Gateway Destination monitor acting up when powered on
My Destination 31" monitor has developed a problem over the last month.
The last thing I did inside it was refresh the solder joints on the VGA connector because the monitor was not coming out of power saving mode and the connector seemed loose. That problem was solved and it worked fine for another month or two, but now whenever it either comes out of power save or is turned on from power down, I experience a very odd effect where the monitor's focus drops out for a split second and it makes a sound like a television set being turned off, but it only lasts for about 1/4 or less of a second. Once the monitor has been on for about 20-30 minutes, the problem is gone with very spontaneous and comparatively minor exceptions. I have no idea how to describe it more accurately but it is bugging me to death. Any suggestions on what to check? Jody |

Check the ESR of all the capacitors in the power supply and scan
circuits. An ESR meter will be required. Change any caps that are out of specs. This is only the start. -- Jerry G. ====== "Jody Bruchon" wrote in message . com...
