does anybody faced with such an error? Any suggest to overcome it? Thanks indeed, Emanuele
This is a rare, but fatal error. Basically it means that the dark current measured during instrument startup is not within specifications. This points to a faulty optical unit. The G1315A is out of support since end of 2011 and we no longer have major repair parts, such as main boards or optical units available. I would strongly suggest to go for a new detector. Alternatively a pre-owned, refurbished G1315C or G7115A should be available at an attractive price.
you may check on the ribbon cable connection from the optical unit to the mainboard, i do encounter the similar error on the new G7117A DAD with the similar error message " diode leakage EE1041,0". After check on the cable connection, the errors message disappear. Hope it help.
It's worth a try, but usually, if the ribbon cable is not seated correctly, you'd see issues like baseline (drift/noise), no peaks, lamp intensity test fails, WL verification fails etc.
In addition, G1315A and G7117A are two different DADs, twenty years apart, based on two different platforms and with different optical units.
