Cinematronics Power Supply Information


All black & white Cinematronics vector games used power supplies that supplied three DC voltages to the game pcbs and monitor. These voltages are +5v, +24v, -24v. Because of the +24v and -24v voltages, swapping in a switching power supply is not possible as it is with other games of the era. If the one in your machine isn't working, its probably easier to simply rebuilt and/or repair it.

Three different companies sold power supplies to Cinematronics during this era. Xentek (older titles), Datapower and Condor (newer titles). They mount exactly the same in each cabinet and have the same pinouts, thus they are interchangable as needed.

Below you'll find more info about reconditioning each power supply. Click on any image to see a larger version.

Xentek Power Supply

These power supplies seem to be the most challenging to recondition primarily due to the difficulty in removing the pcb from the power supply chassis. There are multiple issues to overcome in removing the board:

1. The 2N6055 (NTE243) mounted to the top of the chassis is soldered to the pcb board underneath.
2. There are multi-part spacers that come loose when the 2N6055 is removed.
3. Wires connected to the pcb are soldered directly to the board - no in-line connector

Datapower Power Supply

These power supplies are much easier to recondition. Removing the pcb is a three part process:

1. The 2N6577 (NTE249) mounted on the top of the chassis is socketed and can be unscrewed and easily removed. There is a plastic spacer between the chassis and the pcb board to be saved when the 2N6577 is removed.  
2. Remove the plastic connector from the PCB board.    
3. Remove the pcb from the spacers holding the board to the chassis. When removed the board will look like the image to the right.   datapower power supply pcb

Repair Log:

+5v power supply readings with a multimeter were normal without pcb connected but were low (under +1v) with pcb conected. After pulling the power pcb found cracked solder joints on the connector header pins. Reflowed the solder and the power supply worked perfectly!
