Hello, I've had the same problem with 2 Sony DV cams... TRV 900 and newer HC85. After a couple years of use, the video display and the output to my computer have colored bars across the screen and audio stops working. The moving video can be viewed between the colored horizontal bars while playing back on the camera and my computer. Both of these cameras have been used at hot tropical beaches and to record ski and snowboard footage in sub zero temps in the mountains. My hunch is that extreme temps and moisture have caused problems... question is, can it be fixed?

    Last time I did that, the Sony dealer said I needed a new 'motherboard' to the tune of $500. I went for it, since that camera cost $5000. The fix worked for a short time, then the colored stripes came back and audio stopped working. With camera prices under $500 nowadays, fixing isn't really a very good option. Can you tell by this symptom what is causing the problem?

    The horizontal bars on not gray, they are color. Is there some way to post a photo of the display on this site so you experts can see it?

    Scoured the web and not finding any firmware. Would expect Sony site to have firmware if it was available. Any ideas?

HI,

Thank you for choosing Fixya.com

yes it can be fixed.
just go to the specialist technician and tell to thme what happen to your cam.
correct me if i am wrong some parts of your cam are damage and need to be open to look.
If we don't have proper tools we can't do it by our own.

    Hello Their Again,



    If you are near of any sony store probably they will have a technician ready to help you for your problem if they check that your cam can fix but it will cost.

    You tell us that you already try to quote how much if they will going to change the parts and it is to much expensive right.

    If that will going to be again i prefer to advice you that buy a new one instead of fixing your old one and not so sure if it will last long jsut in case they will fix.



    Sorry to adviced you this but in practically this is the best solution.,



    thank you again for choosing fixya our pleasure to have you on our site.

Please use good quality video cleaning tape to clean video head.
Gray Bars across the screen shows that video head is dirty / clogged and requires cleaning.

  • Anonymous Feb 23, 2009

    well I'm practical technician of Sony camcorders and replying you in this post.

    technically we call it "drop out noise" and "Mosaic noise" and "bar noise" depending on symptoms.

    I'm waiting an image of problem as you said in previous response to understand problem properly.



  • Anonymous Feb 24, 2009

    An image would be fine to understand what kind of bars in playback.
    Please post an image here and file size should be up to 150k in JPG format.
    Thanks.

I need a dcr-hc85 driver for windows Vista where can i get it

  • Windows Vista Starter edition is not supported.
  • The USB streaming feature is not supported with 64-bit Windows Vista operating systems.

  • The drivers required to connect most Sony® cameras and camcorders to a computer are already included in the Microsoft Windows Vista operating system.
    Note:
    In some instances, the camera or camcorder may not be recognized by the computer when connected. In this case, check to see if there is an updated driver available for your model.

    If the above link doesn't work, you can check to see if there is an updated driver at this address:

    Is the memory stick of sony handy cam minidv trv-18 expandable?

    On many cameras , the picture format that you can save on memory stick is not the same that you can have by recording on tapes. It should be tha same on your handycam.

    You can increase memory stick to at least 2GB, that is what sony reccomends, you can test a 4 gb to 16 gb at the shop, if it works , then buy it.

    However, the quality of movies grabbed on memory stick, should be far less than the one of movies recorded on tape.

    Can't transfer dubbed audio (secondary sound) using firewire.

    Audio Dubbing on DV: Here's how you do this: Play your tape on the TRV-9 and feed the signal into the TRV-900, using the Firewire connector. Set the TRV-900's audio option to record in the 12-bit mode. When this is done, you will have the video re-recorded on the TRV-900 and the audio laid down on the primary 12-bit audio channel. Then, you can run the tape back through for a 2nd pass in the TRV-900, with the recorder set to the audio-dubbing mode. The audio you put into the TRV-900 this time, will be recorded on the secondary 12-bit channel. You can select either 12-bit channel when you play the edited tape back or you can mix both stereo channels into the output. Once you record on the 16-bit channel, you can't dub audio back onto that recording, without erasing the original channel, as the recording space for both 12-bit channels is occupied. You can't selectively re-record just audio onto the 16-bit channel either, without the video being re-recorded along with it. Both video and audio are sent over the same Firewire connector, so you can't input them from mixed sources, as you can with analog recordings. Only the secondary 12-bit audio channel can be used in the audio-dubbing mode. You can't dub onto the 16-bit channel or onto the primary 12-bit channel. The primary 12-bit channel can be used only when you're recording video along with it.
