its clearly the fault of the horizontal trace adjust. we had the same problem in our college oscilloscope, but was resolved when we found that there is oxide formation in the variable resistor, and replacing it, it worked fine.

 

[easymylive]

now i do take off the variable resistor and put again ,appear line of right side tube

but when i take signal pulse to input of scope right side tube not have signal

it is just line
