Pro-96 display problem
Hello from Central Florida.
I have had this happen a few times with my Pro-96. The problem every time has been a poor connection of the ribbon cable connecting the circuit board to the front panel assembly. The solution every time has been to clean and reseat the cable.
1. Make sure your hands and tools are clean, and do not contain any traces of oil, acid, or other contaminants.
2. Have metal surfaces nearby so you can touch them frequently to prevent static discharge to any parts of the scanner. Do not walk across carpet or do anything else that might generate static electricity before or during the repair.
3. CAREFULLY disassemble the scanner, carefully noting the position of each screw and scanner part. Take notes to ensure correct parts placement, or take closeup photos.
4. Be CAREFUL that you do not pull any of the cables too far.
5. Carefully pull the ribbon cable out of its socket.
6. Using clean paper, gently wipe the conductors on the ribbon cable, and gently insert a paper or thin card into the socket to clean the contacts of the sockets.
7. Carefully reassemble the radio, and you should have a properly-working display now.
Hope this helps
