No Prob...I had the same problem with my GR-D72U. There is a defect in the CCD image senser. JVC will fix it for FREE! All it will cost you is shipping it to them. Go to http://www.jvcservice.com/service/CustNoticeCamcorder.asp?PgReq=DspDtaDtl&MdlNbr=GR-D72US&Pgm=CCD , download the rapair request... Send it off to your nearest service center and they ship it back all fixed up in less than a week. I must tell you though, you ONLY have until Dec. 31 2008 to do this. Not only did they fix mine, they cleaned the heads but also buffed out a scratch. After you get yours fixed, post as many helps as you can to others.
Use a head cleaning tape - ONCE. Do not re-use head cleaning tapes.
