I picked up two Leader LBO-32B Oscilloscopes at a estate sale. One powers up but the screen is blank, so its good for parts. The other powers up and I get the wave pattern but after about two minutes the wave fades away. The interesting thing is that when I turn it off, a small bright dot slides back on the screen.
I was hoping someone can give me some direction as to what to look for. I'm planing on pulling some parts from one to get the other to work.
Any help would be appreciated.
