Having problems with your Compaq Computer Monitors ?

Monitor width is out of screen

\015 I have this Compaq V55 monitor and the screen width is blocked at maximum, so I can't see part of picture by sides. The H SIZE button doesn't react on anything.I tried to check H.SIZE and H_SIZE rezistors acording to manual (http://www.eserviceinfo.com/download.php?fileid=8154) and replaced R208 with 10k like it is in manual (there was 17k) and nothing happened. The scheme on page 6 has different rezistors than the monitor (R439 has 56 ohms instead 4.3k and so) and I am not sure what to try now.There are some ceramic capacitors, can they be bad ? I can buy new ones soonest next week anyway... What about transistors ?\015

Answers :

Check for shorted transistor, shorted diode, leaking/dried capacitor it could be ceramic or electrolytic. Look for some shunting diode or capacitor that is connected about horizontal size/width ciircuit. Leaking, shorted or open can make horizontal size shrink or expand.
