Step 48: Display Systems: Hack Time.

Get the datasheet for the voltage regulator (and other chips if you suspect them). I used Octopart.com to look up the datasheet by entering the numbers as they appear on the chip. This particular voltage regulator is a "BA055" made by Micrel. According to the datasheet, pin 1 (the leftmost pin) is the "Enable" pin. That means that it turns the regulator on and off. The datasheet also says that it can be connected directly to Vin(the positive power input) to turn the device on permanently. Heat pin 1 with a soldering iron and gently lift it from the circuit board. Solder it to the voltage input.

I really wish Instructables didn't resize images. If you find this hard to read, let me know and I'll upload another, larger version.
