The returned asset device was sent to the service center for evaluation.
The evaluation found the air pressure was low due to faulty air pump unit & worn out air joint unit & connector socket.
In addition, found two of the halogen lamps were missing inside.
The top cover, bottom chassis was deformed & the front panel was damaged.
The four feet at the bottom of he unit were worn out.
The asset device was repaired and returned to inventory.
A review of the repair records show the asset was last serviced on (b)(6) 2017 and met standard specification.
No repairs were performed as the device was returned to asset inventory.
The original equipment manufacturer (omsc) could not perform a device history record review because the production date is unknown.
The omsc shipped the device on (b)(6) 2002.
Based on the investigation results, the potential causes of the reported lamp failure may be attributed to the following: the lamp may have blown, but more than 17 years have passed since it was delivered, and it is assumed that the thermal fuse failed because lamp replacement is considered user-friendly.
It is considered probable that the thermal fuse was blown due to an accidental failure of the thermal fuse or overheating in the device, because the thermal fuse was not restored.
The temperature fuse might have blown out because the user had put other equipment on the air intake and exhaust ports, etc.
, and it was used in an environment in which the conditions of intake and exhaust were bad.
As stated on the ifu (instruction for use) and as a preventive measure, the user manual states: the light source ventilation grill and openings should be clear of ancillary equipment.
Blockage can cause overheating and equipment damage.
