Blank TV on docked Switch 2: collapse the HDMI hops before you RMA
A blank TV with a docked Switch 2 that still looks healthy in handheld is usually a path problem, not a “dead console” story.

Switch 2 docked Joy-Con drops: check Ultra High Speed HDMI first

MLLP Length Fields Lie About ORU Size
MLLP length fields are supposed to frame HL7 v2 messages. When the length lies, your ORU parser reads truncated OBX segments — and clinicians never see the missing analytes.Framing errors at the edgeTranslators often trust declared length over delimiter integrity.

HL7 FT1 Segments Need Encounter Resolution First
HL7 v2 DFT messages with FT1 segments still arrive nightly at many clinic interfaces. Engineers map segments to ledger codes; clinicians wonder why charges appear for visits that were cancelled on the chart. The segment is not wrong — the identity model is. FT1 translation requires encounter resolution Treat FT1 as edge payload. Translate to…
