Sony port replicator and VGA monitors
Here's the sitch,
I have 2 laptops at work that are connected to Sony PCGA-PRF1A port replicators for external keyboard, mouse, lan, and monitor connections. The laptops are a Sony VAIO PCG-632L Pentium 3 and a PCG-GRX 500P Pentium 4. The keyboard, mouse, and lan all work great, no problems. However, every once in a while, especially after they have been out in the field, when the monitor is turned on and connected and the laptops are turned on, the VGA monitors screen is blank. The green/amber on/off light will go green indicating it has a live signal then goes back to amber. I have followed the Sony instructions for making sure that the correct video connection is set but it will take several tries before it lights up correctly. I don't believe it is a software problem as no software, or OS, is loaded at that moment. Anyone have similar problems like this, or a possible solution? Thanks goes out to any replies.
