blurry images

I have a Siremobil compact with blurry images. Power supply voltages are spot on.

Yes, then I would look at the mechanical focus adjustment & camera mount/clamp.

Maybe the licking screw was loose and the focus ring has moved slightly, it does not take much!

If you have an email I can send a couple of images

They have a LCD retrofit and the blur is on both displays and Full and Zoom.  

I'm thinking the unit took a good hit in transport. No damage on the outside but the system was working fine prior.

Is the focus blurred in both Full Field & Zoom?

Assuming you have two monitors, is the image blurred on both monitors? Do you have CRT monitors? 

Think about these things before venturing into making adjustments and making things worse.

There were two versions of focus assembly so it's not 100% easy to explain eactly.

1) Once cover off, under the Camera you see an adjustable (screw) clamping ring. Below this clamping ring you should see a 'long' Allen bolt, this is the locking bolt.

2)  Once unlocked, there is a silver ring with small horizontal holes. Use an EXACT size round bar and this ring should rotate without much resistance. You have to release radiation while adjusting.

3)  When finished retighten locking Allen bolt.

Just an FYI, the mechanical adjustment does NOT normally move unless the locking Allen bolt was loose....Or the TV Camera clamping ring is loose & the TV Camera is loose.

Thanks...Correct the Intensifier supply matched up to the factory test cert.

Where is the focus locking screw and focus ring to be adjusted?

When you say power supply voltages are OK, I asume you mean the image Intensifier power supply voltages!

Are the images blurred on Full Field & Zoom? If yes then the mechanical focus needs to be adjusted. If the answer is no, then you have an II power supply problem.

You can check/compare the II power supply voltages with the factory test certificate if you have one in the service manual.

Mechanical focus: First you must release the focus locking screw and then adjust focus ring.
