I inherited a cabinet with an Orion AM-0316 chassis connected to a 25" tube. It worked fine for about a year, but required frequent adjustments to keep it looking decent. All of a sudden the screen would go crazy after being on for a bit, and the adjustments no longer had any effect. After some troubleshooting, I determined that even after disconnecting the synch wires, there was still no difference in the display, leading me to believe that the synch is lost somehow. The only thing that seems to get it temporarily working again is to turn it off, remove and add the little plug in adjustment board, then power it back on. After doing that, the picture looks fine again for a while. Any ideas or suggestions? Soldering is not in my wheelhouse, and I'm afraid to mess with it, as it may not work at all.
