This CPD-200GS (D-1H chassis) came with "ripple" in the width at top and the bottom. In the middle area the field was narrowed. The whole field was stretched horizontally. R578 was changed its value from 27 Ohms to 370 ohms and Q513 was blown. I replaced these parts and everything appears to be normal but when refresh rate is 60Hz everything is like above mentioned. When refresh rate is 70Hz and up the monitor works very well. Replaced C573 but nothings change.
Any help will be appreciated.
