Hi to All, I was wondering if someone can give me some help in finding the problem on my SG5010 with error code 320, sine wave oscillator error. I would like to troubleshoot it and fix it. I would assume the problem would be on the A14 oscillator board. Does anyone have an idea of which part may have gone bad or which parts I should start to check for the problem. It was an intermittent problem, but know shows the error code continually and the scope does show a bad sign wave. Any help would be greatly appreciated in fixing this unit. Thanks in advance.... jeff
