many people have noted two primary failures with this monitor. i have a couple time-saving troubleshooting tips, which actually apply to mostly all electronic devices. first, of course, bulging electrolytics [capacitors] should be considered suspect. i personally usually replace all the filter [power supply] caps as a matter of practice, since they are the 'hardest worked' component. anyway, a good way to test then [if you dont't have a capacitor tester capable of testing them at working voltage] is to check the voltage across the cap terminals, with your meter set to the A.C. volt scale. it should...
