3. Locate the U29 firmware chip to be replaced on the circuit board, as shown in the
following illustrations.
CAUTION: Do not touch any switches or other electronic components inside the
VSC. Doing so could damage the video scan converter. Electrostatic
discharge (ESD) can damage IC chips even though you cannot feel it.
You must be electrically grounded before proceeding with firmware
replacement. A grounding wrist strap is recommended.
4. After you are electrically grounded, removal of the U29 IC chip requires a PLCC IC puller
tool. To remove the U29 chip, align the hooks of a PLCC IC puller tool with the slots
located in opposite ends of the firmware chip.
