Fixing the ASUS PG221 22" Gaming Monitor

ASUS PG221 22" Gaming Monitor

Recently I fixed the ASUS PG221 gaming monitor, after experiencing some on screen interference, which started to really hinder everyday usage.








This monitor was paired with my UBER PC that I built approximately 10 years ago, a PC that ranked 172nd out of all the millions of PCs in the world that had been benchmarked in Futuremark's 3Dmark 2005.

It was purchased from KustomPCS.co.uk a couple of years after the UBER PC was initially built, and at a nice discount due to the prize money I won after coming third place in KustomPCS' website design competition.
Amazingly the pages related to this are still active, with the competition page being found HERE, and the winners page HERE.

Until recently it has been nothing but reliable, and being packed to the brim with functionality, has served me well.
It was because of this that I decided to repair it, and found that the issue laid with some faulty electrolytic capacitors misbehaving on the power supply board.

 I replaced the entirety of the electrolytic capacitors so that they were all new, and from high quality reliable brands (Panasonic and Rubycon), prolonging the life of the repair.
Doing this drastically reduces the odds of having to reopen the monitor to replace any further capacitors that may fail, as they are now all new, with a similar lifespan.


ASUS PG221 Monitor Repair


As you can see in the video, this monitor is now back up on its own two feet... or singular round foot in this case. =)




Further advice...

This monitor model has always been prone to heat issues, so running it with a 120mm fan hung over the top vents via a custom mount goes a long way to prolonging the life of the monitor, which is something I have been doing myself.

Faulty BGA Nanya Memory Chip

These symptoms can also be caused by a faulty memory chip on the controller board.
This is a square black chip sporting the name NANYA. If this chip is to blame for the fault, careful replacement of this chip or a brand new controller/mainboard is the only solution.





Faulty Inverter Transformer

Another common fault with this monitor is the screen going black after it has been switched on.
This is due to a faulty inverter transformer, and can be solved by replacing the faulty inverter transformer, or by simply replacing the whole power supply board.




If you have been having issues with your ASUS PG221, hopefully you now have some answers, and most of all thanks for reading. =D
