Re: New Members - please post your introductions here

Hi,

I have studied electrical engineering in school, but 99% of knowledge seems to come from hacking stuff apart and reverse engineering.

I mainly am curious about repairing broken electronics and to use that knowledge in designing new devices.

Re: LG 27GL63T-B completely dead

Another success story:

So similar symptoms, IC401 did not get hot, but little warm, so it stuck out on thermal camera. The short near audio jack turned out to be pull-down capacitor. Probably it's shorted when there is no audio jack inserted in the port. But also IC401 had no output voltages, so the device acted dead.

I replaced my IC401 with part named MP2149GJ-P (the original part has been retired) and the monitor started working. YAY!

The MP2149GJ-P is also rated 2A (original part was rated 1A). Not sure...
