Newbie level 2
I just purchased a oscilloscope from ebay not too long ago. I recieved a Philips PM 3055. I turned it on and the lines were not level or centered. I used the trace rotation knob to asjust the level, so it is flat now. The problem I have is the line wont center. I adjust the x-axis as far as it will go, and it doesnt come close to reaching the center (I will take a picture). I was wondering if any of you know how to fix this. My friend told me it was a potentiometer inside, so I opened it up and there are lots of pots on the top board. If anyone can guide me to fixing the screen, I would greatly appreciate it.
Thanks for your help.
