Hello,
I just purchased a BK Precision 2120B oscilloscope, to help me with my projects and such. I got it from ebay, the seller had a 95+% positive rating, and said that the unit had been used for about an hour, and is as good as new. It arrived today, and needless to say, I was very excited. I couldn't wait to avoid more homework, because I got my new toy I plug it in and turn it on, and the CRT does not turn on. I have no idea how to even begin diagnosing the problem, but I did take the cover off (after unplugging it and letting it sit for a while, of course), and looked for burns/fried components/bad caps. I found none, and apart from a few cobwebs and some dust, the unit looks pretty good on the inside. Some of the caps are from a brand called Engel (ever heard of them?) and the rest have a logo which is a capital A in a rectangle.
They made good use of screws and take-apart-able connectors, so disassembling the unit won't be too much of a problem, I'd just like some advice on what to do or how to start.
I tried to get some pictures of the circuit boards without disassembling it.
I searched online for a schematic and couldn't find one (I did find the manual though). The power light comes on, so I know something is working. I'd be happy to take more pictures, and any advice anybody can give is welcome
Thanks!
Eric
