SUMMARY

The monitor explosion was likely caused by a blown capacitor in the Viewsonic GS790, a model approximately 5-6 years old. Despite the incident, the monitor continues to function, albeit with a shifted image that can be corrected using the On-Screen Display (OSD) settings. Users should exercise caution when continuing to use the monitor, as the failure of a capacitor may indicate potential future issues.

PREREQUISITES
  • Understanding of monitor components, specifically capacitors
  • Familiarity with On-Screen Display (OSD) settings
  • Basic knowledge of electrical safety
  • Experience with troubleshooting display issues
NEXT STEPS
  • Research the role of capacitors in monitor functionality
  • Learn about safe practices for handling electronic devices
  • Investigate common issues with the Viewsonic GS790 model
  • Explore repair options for malfunctioning monitors
USEFUL FOR

This discussion is beneficial for electronics enthusiasts, monitor repair technicians, and users experiencing display issues with older monitors.

Last night, something exploded inside my monitor. It generated some smoke which I could smell. I pulled the plug as fast a possible, but after a some time past I got curious and plugged the monitor back in and turned it on. To my surprise, the only problem was that the image was shifted to the right. I moved the image back to the left with the OSD and everything seems fine now.

Does anyone have any idea what happened? Did a capacitor blow? Is it safe to continue to use the monitor? I have a Viewsonic GS790 which is about 5-6 years old.

Could be a bug.

Definitely sounds like a capacitor blew. If it was in parallel with some other capacitors, the monitor may still work fine -- you just now have a more limited total range over which you can move the image.

I'd be cautious, though.
