Power supply board layout

Most likely the power supply board needs to be replaced. Viewsonic is notorious for failure, it may not be worth trying to fix.

If you don't know what you're doing, DON'T OPEN THE MONITOR UP TO FIX IT, THERE ARE HAZARDOUS VOLTAGES ON THE POWER SUPPLY BOARD, EVEN WEEKS AFTER THE MONITOR IS UNPLUGGED!

If you don't know how to do it yourself, find some local Electronic repair shops, get quotes, try to find reviews on the shops.
