Replace the main board (VILIS - Themis)
Swap the DryStar 5300's Main board — the source calls it "Main board (VILIS - Themis)," spare part CM+343335.X — by working through the Top cover, the Front and Right side covers, the network and null-modem cables, an EMI shield held by 5 screws, and 8 labeled connectors, then sliding the board out.
Applies to
Drystar 5300, Type 5365/100 (source Chapter 3.5 §2.6, Repair and Service: Replacement of Parts, Edition 1, Revision 7, 2005-08-05) — replacement procedure for the Main board, spare part CM+343335.X, which the source labels "Main board (VILIS - Themis)".
Personnel
1 technician · Intermediate — open the Top cover, remove the Front and Right side covers (cross-referenced procedures), disconnect the network cable and (if fitted) the null-modem cable, remove 5 screws (A) and lift off the EMI shield, unplug 8 labeled connectors (1-8), loosen 2 screws (B), then slide the board out; re-installation reverses the same sequence. No calibration or software step is stated in this section, but correctly tracking 8 numbered connectors plus two separate screw groups (A and B) raises this above a basic cover swap.
