Cameras, lenses, projectors
The time has come to retire and we wish to advise that Camera Check Point will cease operation in June 2018.
After 37 years of operation and repairing well over 25.000 cameras and lenses, we plan to take it a little easier.
The cost of old lamp types has increased dramatically and the last few manufacturers are gradually phasing them out due to low demand and high cost of manufacture.
These lamps have an expected burning life of 15 to 25 hours when correctly used and adjusted. On this page I will explain how to make the lamp last its expected time and to how to avoid premature lamp failure.
Two types of lamps are used in projectors -
Unless the lamp exploded you can often tell why it failed, and here are some examples.

If the lamp only lasts minutes, gets a whitish film inside and all the filaments have blown to pieces, then the lamp has leaked air.
This may be due to a manufacturing defect, a drop or impact in transit.
Such a lamp may be replaced if it is returned promptly within 10 days.
This lamp is almost certainly at the end of its normal life.
However, the slight blistering is also an indication that it may not have been positioned correctly in its socket.
When a new lamp is fitted its position should checked and adjusted immediately, and before any use.
This is typical of a lamp that either wasn’t adjusted correctly, OR, where the mirror in the projector was displaced (indicated by the different levels of the bulges).
Such a failure is not covered by any warranty and is a good reason to ensure a new lamp is correctly adjusted.
