tektronix 2465 power problem
Hi, I am new in this group.
I have a Tektronix 2465B scope which has power problem. when power it on, all the GPIB Status lights are on, fan is moving, but no display seen. I don't have a service manual. But I measured the center pint at J4244, it is +4.3v to ground. Other voltages on J232B is -11.3v and +4.3v. Both voltages look like loss 0.7v. What parts, or section will cause this kind problem? Any help, or light are greatly appreciated. feng |

I replied with a detailed message a few years back on 2465 power supply troubles. You should be able to google search it. I don't have access to a manual anymore. They did have problems with filter caps and fans. Take Care |
