I have hooked my cable into the back of my set and the picture is fuzzy unless I push on the cable. The connector on the back of the T.V. seems loose. Is there anyway to fix the connector?

Picture gets fuzzy especially the writting on 2000 Sansui tv


This could be multiple things. If the fuzzy picture is on your regular cable channels and the tv is hooked up directly to the cable then it is a signal issue. Your cable signal is probably too low because it is either split too many times, a splitter went bad, a piece of cable went bad, you have RG-59 cable rather than the much better RG-6 cable. Another solution is if there is a vcr hooked up, the cable jack on the vcr could have gone bad, the vcr power could be on which will cause a fuzzy screen. If you have a vcr try to bypass it and hook directly to tv. If that fixes you problem then it may be the vcr or the wire from the vcr to the tv. If you have no vcr then I recommend buying a cable amplifier and hooking it up. This is a band-aid solution but it could work long term if it's just a matter of weak signal. If that does not fix your problem I would recommend calling a cable professional to evaluate your problem. Could be the line from the pole to your house or any of the wiring in your home.

When using cable input video is good but sound has fuzzy static


Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.

Hello: Your problem seems to be in or around the tuner of the television, More then likely you have cold solder joints on the turner that needs to be resoldered. Also check the coax end protruding from the back of the set where u connect the cable and make sure it is not loose, a bad ground on this connector to the turner shield will cause this symptom. My professional diagnostic is that when the television is cold the solder connections are making contact with the board, and as heat builds up in the television while watching these connections tend to seperate and make limited contact, causing fuzzy picture and in most cases no picture just snow...

FUZZY PICTURE


1 thing you can try. sounds silly but. the older a TV is the 75om cable in the back. un hook it, clean it with a tuch of alohol, and the post it hooks to. dry it good. and put it bake on tight. must times the white line come from a dirty, wore out, or bad cable to the set. best way to test this is wiggle the cable behind the set. if the intenstty of the lines change, it's you cable. replace is. hope this helps.

After auto channel set up, how do you get to Channel 3 for DVD?


Try pushing "03" on the remote. You can also edit the channel list manually, and add or delete any station you desire if the autoprogram does not work right. You really want to connect the DVD to the audio/video inputs (Does it even have an output that connects to the tuner?) anyway. Most DVD players, unless they also contain a VHS player, don't work the way you seem to think they do! Even if you have a machine that works through the tuner, you won't get the best picture or stereo sound unless you use your TV's A/V (or "Line In") plugs with a three section cable having three RCA plugs on each end, NOT the screw-on cable TV or antenna type connectors (RG-59) on a SINGLE very stiff coaxial cable. I am as confused by your question as you are! I don't suggest trying to brush your teeth with your TV either. :-)

Check the cable type settings it may be a switch on the back of the set or by the antenna input or at the bottom back cover . If no switch then if theres an on screen menu it should be somewhere there. if theres no on screen then theres gotta be a switch. this switch changes the AFC on cable systems from irc ,mirc or normal try all three settings one at a time while changing channels thats where this works . Good Luck

Fuzzy signal


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.
