Monitor Repair

Leave a comment
My 22″ Acer monitor died about a month ago. I did a little googling and found that this model has an output transformer prone to failure. It was a $20 gamble that paid off (new transformer from lcdparts sitting on the bubble wrap in the photo below ). About 45 minutes round trip, the majority of the time was spent figuring out disassembly. Photos were an important trail of digital breadcrumbs that I used to get the monitor back together.
Awesome video on the basic function of an LCD monitor here.

The only soldering were the 8 pads circled in red above that needed to be desoldered to install the new transformer

OT transformer in red again, the white blobs of silicone popped off with tweezers and glued back in place after soldering with a little roasting with a heat gun.

Back in business!

CMOY FIN!

Great project from tangentsoft! I’ve been looking for a good headphone amp to push my Grado SR125’s on the road. The CMOY is a great solution, based on the awesome Burr Brown OPA132 Op Amp. I plan on building a large cap version for my desktop.
