CFV-50 ccd servicing

[dece]

I have a CFV-50 CCD back (bought new in 2012), that still works fine but shows more and more hot pixels (with ACR, via phocus they are ~removed) = sign of aging; is it worth servicing it?
I see on hasselblad website

CCD / CMOS CLEANING

A CCD / CMOS cleaning includes a number of operations to ensure that the camera performance is in accordance with factory specifications – no matter the age of the camera. This is what we do:
Firstly, the IR-filter which protects the CCD / CMOS is removed. The position of the CCD / CMOS can then be measured and, if necessary, adjusted.
A focus calibration is followed by very careful cleaning of the CCD / CMOS with compressed air, cleaning fluid and tissues.
The unit is then mounted on a test bench. A test shot is made through an illuminated piece of opal glass mounted in the filter thread of the lens with the lens focus setting at infinity. The unprocessed RAW-file is inspected on a monitor to ensure that that there is no residue of grease, fluid or dust on the sensor.
A mounting seal is attached and another test shot is made and inspected. The IR-filter is now unwrapped, cleaned on both surfaces and mounted.
The camera then undergoes a full factory test to ensure that the camera still performs according to the factory specifications – no matter the age of the camera. If needed, extra calibrations will be done, or parts will be replaced to ensure correct performance. You will be contacted if the cost of such replacements makes the service charge exceed the current cost estimate limit.

has anybody here tried that?

(btw does anybody knows what happen when such sensor dies? it's unlikely that Hasselblad has a stock of old CCDs ?)

I contacted them about ONLY replacing the IR filter on a CFV-16 a few years ago and if memory serves (it frequently doesn't, or so my wife tells me, repeatedly ) they quoted about US $400.  At the time there was a company in Europe called something like B23 (maybe) and they did it for about half what Hasselblad was asking.  They were very good technicians, but I have no idea if they are still in business.  The CEO was a previous repair manager for Hasselblad who opened his own business.

When the sensor dies I rather suspect you have a fine paperweight

Seems that they are still in business.

Jimmy + team at B23 Aps Denmark are absolute superstars

Earlier on in the year, we had our Hasselblad V96c (square 9μm pixel CCD) digital-back serviced by B23 with the v.1 IR filter changed-out for the new v.2 IR filter.
He also repaired the flash-sync too, which was very kind. The back now both looks + handles like new!

Superb service
