DLPlampxpress equivalent replacement bulb ran for approximately four days and failed. So my wife contacted Mitsubishi for replacement bulb and we returned the failed bulb back to DLPlampXpress for replacement and wouldn't you know... "it worked fine when tested" and "you may want to find a servicer to further diagnose your problem". So I suspected maybe a problem with the balast, so I contacted Mitsubishi for replacement ballast.... Mitsubishi instructed us to use the new bulb (from Mitsubishi) before further diagnoses. The exact replacement ORSAM 180w bulb has been running for 19 days now!
Why would an equivalent replacement bulb (ORSAM 150/180w) not work after just a few days? DLPlampXpress has not responded to request for exact replacement or refund.
