irtrans remote control stops working

I’ve been using a Zalman HD160B media center case for quite some time, and I love it. It came with an irtrans based LCD and remote control built into the case, which has always worked nicely as well. Until yesterday when the remote stopped working.

When I run the irserver command in a terminal so I can see the output, I get this:

    # ./irserver -codedump -debug_code -loglevel 4 /dev/ttyUSB0
    Name   :
    Version: D5.03.08
    FW SNo : 18780
    Capab  : Power On;
    FW Cap : 3964953
    USB SNo:
    Node   : /dev/ttyUSB0
    IRServer Version 5.7.08
    [ 0]:                      D5.03.08     SN: 18780
    Remote zalman               compiled:     1 Timings -     45 Commands
    Total:   1 Remotes  -   1 Timings -  45 Commands
             0 CCF Data -   0 CCF RAW -   0 CCF Error

No joy. Rebooting the machine, replacing all the batteries, and restarting the server all did nothing. The server still doesn’t see events from the remote. I’m not sure how to determine if this is a receiver hardware problem or not — I’m kinda out of other ideas. Suggestions welcome.

Update: of course, disassembling the PC and reseating all the cables fixed the problem. I wonder if it is temperature related?
