Broken Horizontal setting on monitor
 

Hiyee,
My friends has a Compaq Desktop (7400), however it's horizontal setting
on the monitor seems to be broken...even at the lowest setting...it remains
stuck at the highest setting...are there any problem prone areas I should
look out for?? I'm quite competent with electronics...I've a good DMM...and
a 20Mhz scope...no CRT tester though...any tips on how to fix it would
really help me a lot. thanks in advance.
Regards,
