Hi
Its vertcial output section has the trouble. It is composed of and IC and surrounder components. If the electrolytic capacitors, or IC itself can cause this. Just open the monitor, and access the vertical output section. Look for any buldged or leaky capacitors on that side. Just resolder all the solder terminals of vertial output IC; by applying a little more solder, without making any solder bridge in between adjecent terminals. Loose solerings in circuit may also make this type of fault. If it doesn' help you, just repalce all of the electrolytic capacitors on that side first. There will be 6 or 7 of them. Replace it all at the same time. it won't cost more. If the fault still perists IC is damaged, and should be replaced with same type and number. OK.
