hi, these are exellent monitors. i have repaired and made good profit on these. there is about 8 capacitors on the main board that go bad. all are 470uf 25 volt. if you have good knowledge of soldering, you can perform this repair. even broken, these monitors go for 100 dollars on ebay. contact me back if you want more info on how to repair yourself.

There are 6 (reduced quality) capacitors in the BenQ Q9W5 which cause the screen over time to 'fail to sync' when turning on or resuming from standby.
4x 470uF 35v, and
2x 1000uF 16v.
I recommend the following replacements if you are in Australia (the ones I purchased from Jaycar only lasted 12 months);
