Leukhardt 703.02.2.200.B board
 |
Leukhardt 703.02.2.200.B is the main controller board used in the Dialog 4‑FT touch‑screen station and related control units. Common failure modes for this card include power‑rail voltage drops or spikes, burnt capacitors/diodes on the high‑current bus, solder‑bridge shorts between I/O traces, and firmware corruption that triggers a watchdog reset. First‑check diagnostics should verify the board’s 48 V input supply and monitor the regulated rails with an oscilloscope; inspect for visible burn marks or loose components; and read any diagnostic LEDs or error codes from the host controller to isolate the fault source.[oss-gpt-20b] |
