Trace Oscilloscope Works

What would cause an oscilloscope to stop displaying a trace?

I just got a tektronix 2215 oscilloscope from Ebay. the seller said it worked fine but then stopped displaying a trace. so I got a deal on it. does anyone know what might be the cause of that? could it be something simple like dirty switches or a blown fuse? just trying to get an idea so I know what I'm getting into. I haven't received it yet so I can't physically check it out yet.

Could be dozens of problems, all of them serious.

First thing to try, is there any image on the screen at all? If you see a dot or vertical line, then it's the sweep circuits that are out. If there is nothing, it could be anywhere in the cRT, it's drivers, the power supply.

If you can't find anything obvious like a fuse, send it to tek for repair.

Wow, you bought a totally non-functioning scope. Hope you didn't pay more than $10 for it. If so, I have a bridge you might want to buy.
