General Information · Repair Cautions

The PX-769N is a 17 inch CRT monitor released by Proview in 2001. This page should also aid in repairing the similar 786, 778, 720, and 722 models. These models all share the same general design with slight feature differences such as an OSD or speaker cable ports on the sides. This monitor had several revisions (between 3-6) so be sure to check if your capacitor values match.

Known Issues

Symptom or Problem Encountered

Partial Vertical colapse

Causes

Solutions

Wavy distortion horizontally

Disassembly Notes

There are four screws holding the back cover on. Simply place the monitor face down (preferably on something soft as to not damage the display) unscrew the four screws and lift the cover off. To remove the PCB you will need to de-solder the grounding leads between the neck board bracket and the tube. You will also need to carefully bend out the bracket holding the PCB in as it has clips holding it in place. Be sure to remove the ribbon cable holding the front PCB with the buttons.
