Hi, I built a HM for a friend of mine and it was damage by "dropping it" or something.
I am trying to figure out which components are problematic. Right now, everything works except for the LCD.
I replaced the LCD with a new one and it still isn't working. The only new thing that seems to have happened since I attached the new LCD is that the yellow and red LEDs are on the whole time. I did make sure it wasn't the brightness of the LCD being all the way off.
I don't know how all of the electronics work in order to troubleshoot and/or replace potential faulty parts. Can anyone help?
BTW, it must take mad skills to desolder! I tried for an hour or so with a wick and although I removed most of the solder, I couldn't get it to come off. I ended up with a dremel and a really tiny grinding sphere that was the perfect width to fit between the individual pins. There must be a better way.
Thanks!
