these bulbs will check open circuit with ohm meter
suggest letting authorized servicer work on if unfamiliar with product
if lamp fails to light unit will shutdown or not come on
usually have problem in ballast power supply
difficult to get to and troubleshoot w/o s/m.
to test for bad buln you sub most any metal hydride lamp
