My Toshiba is about 3 years old with no problems up until now. I have a DVR cable box with it and when I turn on the cable box, it's fine, but when I turn on the TV, it's fuzzy. This hasn't happened before. I checked all of the plugs and they were ok. I restarted the DVR box but that didn't work. What should I do?

If you have the DVR connected to the TV with the Coaxial and the HDMI that is probably causing the problem I work for a Cable company and have dealt with this problem on numerous occasions. Try just disconnecting the Coaxial cable from the cable box that should fix this issue.
It sounds like a problem called blooming, or you are having a problem with focus control which are signs of a problem in the horizontal and high voltage section of the tv in the case of plasma TV this would be the excitation circuit. I would suggest that you take the set to a TV repair shop to effect repairs.
If your menus on the TV and other inputs look good then it is probably a resolution setting on your Directv box that needs to be changed. To get HD it needs to be set at 720p or 1080i. Please take a moment to rate my answer. Thanks....
First - I did not send in my question when I realized yours was a pay-for service. No offence, but I generally try to exhaust all approaches I can do on my own before going to paid assistance. Yes, it probably takes more time - but my rate is pretty low (ha).
Anyway - what I did was turn off and unplug the TV, the DVR and the Cable box, and
let them all sit from the time I left for work in the morning until I got home that night, about 12 hours. When I plugged everything back in - cable box first, then DVR, then TV, if that matters - everything was working fine.
I am not sure what caused this problem to begin with. I don't think it was the cable company (Comcast) because when I disconnected the TV from the cable service entirely the set was still blinking on it's own. I guess it is possible that the cable co triggered something - but how? We did have a loss of service from them for Internet access the day before the TV problem, but the set didn't have any problem until the next day. My wife thinks it was because the kids were playing a Wii console game before the trouble began - but the kids play with the Wii often enough without any later problems.
So, the set is working OK again and I am not sure why - can't get any good info from Mitsu on the web ....oh well .... now if I could just get the darned remote to work.
Right, but the problem is more likely the tuner unit-which the coaxial is hooked up to. If it was strictly the coax, when you wiggled the cable around, the image would probably come back fine. Youll have to get a tuner and solder out the old one, the solder in the new one. The tuner for your model is part QAU0305-001 found here: http://www.jvcservice.com/service/JMdlPrtXrf.asp?PgReq=DspDta&MdlNbr=AV-32432
Be aware that the problem could be as simple as a diode or cap...until it can be tested we don't know for sure. techman would probably know more about this model than I would.
