Sony CCD-TR805E Auto focus and manual focus...

lens inside camera may be struck, open take out camera free the lens control motor or replace it

if you alsow get vibrationOn Sony T100 and similar,
its the vibration canceling unit, i had the same problem.
if you have good hads you can fix it.( on your oun risk)
1) disasamble the camera, you will see black plastic box inside, this is he lens unit.
2) on the botom you see 2 scrwes, they are holding the CCD remove them and the ccd unit will come from the lens assembly
3) the next is the stabilizer unit it is the problematic one. it is located on the left side of the lens asebly and is held by 2 screws.
you can test it by puling out the cable connected to it (the conector is just under the lens) and verifign that the problem is solved. ( you can leave it this way it will shoot fine just without the anti shake)
4) to fix it take it out ,remove the plastic cover, you see the lens on a plastic mount it should be glued to the magnet under it. the problem is that the glue fals apart.
remove one of the pins on wich it slides, and take the lens and the magnet out.
5) reglue the magnet and reasemble the camera.
6) power up and test, for me that solved the problem

if you need more help you can mail me at adisarit(et)yahoo(dot)com this is spam mail so be prepared to wait a few days for reply.
this was tested and worked on 2 additional cammeras

Gee I have one of these. Nice camera too.

Check you don't have the auto focus switch on the left side of the lens barrel switched to manual. I've knocked that switch when getting it out of my bag and it took me a minute to find the fault. Very easily knocked so keep an eye on it. Go through your menu and make sure everything is as it should be. If everything checks out I'm afraid it's a Sony repair agent you'll be saying hello to. I wouldn't advise trying to pull it apart yourself unles you are confident. I pulled my second one apart and had a great time getting it all alighned to put back together. Mainly because I pulled it down one week and waited another 3 weeks until I tried reassembling it. Always try to reassemble straight after fixing it. Don't give that brain time to forget important parts and where they go.
If there is a fault it would be in the lens area but after owning 2 of them and the 818s I found no problems in this area and never had a customer have any problems there either. But there's always a first time.
Try that darned switch first though. One other thing it's just possible to try. Make sure your battery is fully charged and in good health. They can cause some weird faults if the voltage is getting low. The focus motor does draw a bit of current.

There's another thought. If the auto/manual switch isn't the culprit. Actually switch it to manual and see if you can focus it by hand. If you can't then it's definitely something major and one last thing. Check your Diopter.The little adjustment alongside the viewfinder. If this is out of adjustment it will give an out of focus blurry look too.

If this has been of any help would you mind letting me know what the exact fault was. It will come in handy with mine. Thanks and good luck

It is likely to be an issue with the auto focus in the lens. You will get the grinding noise even if you switch the camera on in manual focus, but not if you take pictures in manual focus.

If it's in continuous auto-focus and doing it, then it is just not locking on to one thing and jumping back and forth between two objects that are very close together in distance and it is normal. It should stop in manual, single shot or single point auto-focus. Sony uses Nikon auto-focus technology and my D-300 with a 70-200mmf2.8 will do it if I turn the auto-focus tracking time(lock-on) all the way down with the auto-focus in full auto.

A mirror lens is a specialty lens. It's a huge telephoto, but shrunk by using mirrors (hence the name). It's a fixed F8 aperture, no auto focus. Looking on the web, this seems to be AF but from a number of uses it "hunts" as due to the tiny depth of field. It's for photographing items at least 300 feet away. The depth of field is tiny (area in focus). You may have to to turn off any "program" modes. This lens will work in "auto" mode where the camera chooses the shutter speed. A tripod is almost a must. Since you have a digital camera... go out and try it... just delete the out of focus and blurry ones.

Andy, have you tried other lens??

You may have problems with leaking capacitors, if is that, the repair may not be the best choice.

If you have leaking capacitors, then the acid leacking, possible have compromissed the mainboard.

Base on my experience with Sony CCD's, if it was the CCD, you would have NO picture. Odds are that the problem is the auto-focus circuit or the focus motor/gear. Either way it's highly unlikely that a shop could fix it, let alone trying it yourself. It's usually easier to just replace the Lens Block, but unfortunately, that usually runs around $150....for the PART.

that problem is on the lens assembly...one the two motor is not working properly...sometimes it is a poor connection to the socket of the main board...other is photo sensor of the lens(not the ccd image sensor)or the driver ic of the 2 motor...i suggest you have to go the service center for repairing you camera cause it need to disassemble the camera for doing this....
