I fixed the broken LCD!
I was given a broken LCD that had some issues with turning on and make a cricket(chirp) sound. After inspecting the insides, I found the problem was a broken power supply. The cricket sound is caused by a capacitor not working correctly and that caused the transformer to make a chirp.
I was not sure which capacitor was not working but they were all poor quality capacitors and I did not want to reopen the LCD later to fix it again, so I replaced all 7 of the capacitors. The capacitors are not expensive and it did not take very long to replace the broken ones. A few of the new capacitors are slightly bigger but the size did not cause any problems.
I have included a few images of the process…
