TEK 475 with only a dot as the visible display, capable of vertical movement by knob manipulation, but no horizontal. likely to be a straightforward fix please? Thanks. |

It may be reasonably straightforward finding the fault, if you know a bit about fixing electronics. If the horizontal position does nothing, then it sounds like the problem is in the horizonal Amp stage that is all discrete transistors - no custom IC. Probably a fair chance of a repair.

I have the same scope, and i just want to make sure what you are seeing. 1. you can move the scope trace up and down on each channel using the knobs next to the input right? 2. When you move the horizontal adjust knob below the screen, the dot still stays in the middle? can you answer a few more questions? 1. was this scope working before and just stopped? Oh and is this scope new to you or do you have experience with it? (just asking) 2. when you change the time base does anything happen? Jon |

It's a scope I have left a low bid on, not sure if I will get it or not. The info I gave is all I have to go on I am afraid. If its beyond hope I can break it for parts, it won't have cost me much. Thanks for the reply. |
