Awesome! sounds like I should be able to fix this! I understand most of what you're saying, and if I can find these schematics I can get started troubleshooting....which might prove difficult for me. I'm not very experienced and this is the only scope I have, so that leaves me with a couple multimeters to get the job done. I'm going to read the "readout system" a few times to get a grip on whats going on...and I found the schematics, except "diagram 9" is missing, which seems to be the one I need...
I do have a 30 day return policy on the scope, but it sounds like you think it's fixable. Although I'm still going to try to fix it in the some 20 days I have left. If I can't which is probable given how busy I am, I should keep this thing right? Twas only 50 bucks, but I'm not sure I want to spend another 50-100 and go through the trouble of finding another scope.
