I've generally had good luck with JVC projectors too and still use them, but they had some specific models that had problems with the boards.  I looked back at two that I could remember and they were both DLA-RS40U models installed around 2012-2014.  I had 1-2 more that might have been slightly different model numbers but installed in the same 2-3 year time span and none of them lasted longer than three years.

The symptom was solid red "Warning" and "Standby" indicators with the Lamp indicator giving two short flashes in orange which sounds exactly like the symptoms Golden is reporting.
