Sensor problem.
 
Hi...I seem to have a number of dust particles on the sensor ( NEX3)...I have removed these with a bulb syringe. Looking with a torch and magnifying glass I can see 3/4 small particles that seem to be behind the surface of the sensor and resist any attempt at removal. Any ideas? thanks.

Try with camera cleaning brushes and air blower.

While cleaning keep in mind that you need to clean when
>Remaining battery icon shows three marks or more.
>Use an AC Adaptor AC-PPW20.
>Do not use a spray blower.
>Hold the camera face downward to prevent the dust from resettling in the camera.
>Do not apply a mechanical shock

You need to buy a dedicated sensor cleaning kit from Amazon.

Eclipse fluid and pec pads are usually included. You can then look qt YouTube videos demonstrating the procedure.
Basically, take test shots of white paper with a small aperture, that'll show the extent of dust particles.

Mount the camera on a a tripod with the sensor facing downwards slightly to prevent dirt falling into it.
Wipe only ONCE in each direction with each side of a clean pec pad. Left to right then vice versa with the other CLEAN side of the pad.

Take another test shot and inspect the image, compare with the pre cleaning image.

Sorry I can't be of more help as I'm not at home with my SLR equipment and cleaning kit and computer available, relying on 7" Fire tablet to post- but that's the way it's done and usually gives excellent results.

The cleaning kits are about a tenner from Amazon. Eclipse fluid and pec pads can also be bought separately.

Hope that helps. Maybe one if the others eg Ian, Garry Graham etc would step in if I missed anything important.

P.S ... Ipri, make sure the battery us fully charged before you start as you don't want it to close down during the procedure.

Seeing as Ipri asked this question way back in 2014 My guess is that he must have got it sorted by now. :rolleyes: Still it's good advice for anyone else that has a similar problem. :\
