Hi Mark,

The first thing to do is check that the sample compartment is clear and there is nothing blocking the beam.  The instrument is getting stuck during boot-up because there is too little light being sensed by the detector.  The most common cause for this is that a cuvette has been left in the sample compartment by mistake.

If the sample compartment is not blocked, the next most likely causes of this error are:

  1. There is a problem with the filter wheel and it's not turning to a point where it passes light when it's supposed to.
  2. The lamp has reached the end of its very long life and there's no light coming from it at all.  You should be able to hear a familiar high pitched buzz when the lamp fires.  If you are not hearing that buzz during start-up and your instrument is over 10 years old, it could be the lamp.

In both those cases, this is not something that you can fix yourself.

If you are in North America you can call Thermo's technical support team toll free at 1-800-532-4752 and they can help you further.

Outside the USA, talk to your local Thermo Scientific dealer.  If you purchased from a catalog house like Fisher or VWR, they should be able to tell you where to get technical support or repair service.  If you purchased from a smaller more specialized dealer you can probably get support directly from the dealer.


Good luck!
