Actually, on page 12 it shows something for U26 & U27. But the way they are positioned on the board, the layout, is different then my board...What do the numbers refer to? U26 (10-01) and U27 (11-01)

spisi:
Also, doesn't show the battery :dunno

Part designators on schematics and PCBs use letter prefixes to identify the type of part and a numerical suffix to identify which one of that type of part it is.
- R2 = resistor #2
- C5 = capacitor #5
- D4 = diode #4
- U26 = integrated circuit #26

Not sure what the "10-01" and "11-01" ICs do.
- Might be custom chips. Might be re-labeled standard chips. :dunno
- The manual I linked to earlier doesn't have the schematic for the Cinemat Main Logic Board P/N 81-14040-01. (found the P/N on page 33)
- There appears to be a missing schematic page between 43 and 44, but one page isn't enough for the Cinemat Main Logic Board.
- Did your cab come with any manuals?

The different positions for U26 and U27 on your main board sounds like a different version PCB.
- Is your main board marked with a P/N and revision number or letter?

Here's a manual for the Cinemat System, Rev C. that might be useful.

Battery schematic is on page 44, lower right corner.

There should be 2 batteries, B1 and B2.
- B1 is the purple one in your pic.
- Is B2 hiding behind B1 or are both batteries part of a single assembly?

Did not come with a manual. I'll try to gather more info when I get home later today. I'm going to test the old battery also. That's the only battery that I see, unless it's somewhere else on a different board. I'm looking in the lower right corner of page 44, and I can't make heads or tails of what I'm looking at...
