I just purchased a used Polaroid 26" LCD HDTV. I went to hook up a basic cable line to the television. The Tv works and I am getting cable channels, but the problem is the picture is really fuzzy and really unclear for almost every channel. I know that standard definition won't look good with a high definition tv. I was thinking that the tuner in the tv is bad or possibly need a new VHF line. What do you think the problem is and how can I fix it? Thanks

Re: Bad Cable Input
Try using your RCA imput to see how the picture looks compared to the tuner picture,is possible your tuner imput is bad,make sure the conector is not loose,the overall picture should look different but not fuzzy all over,using a dvd picture thru the aux (rca)imput should show you the difference.If the conector is loose only it could be repaired but if it is solid the tuner might be bad and it will need to be replaced along with any board it might be mounted to.Let us know how it goes or if you need more information.

The cable box needs to be set to send different signals when using hd tv and standard tv. Usually a good setting would be 720p in hd and 480p in standard. The tv is working fine it is the cable box sending the signal. If you have another hdmi source such as a dvd player you may hook that up to show the tv is working just fine.
Are you using component video (red/blue/green) rca jacks, or composite video input (yellow) rca jack? You need to match the color but watch out and do not get confused with the red and white RCA for audio.
Sounds like you mabe be on the wrong source. Try hitting the input button on the side of the set to change inputs. Input channel up or down find tv hit input again. If on the wrong input you will only get a blue screen and message no signal that will apear for a few seconds.
Hello, the HDTV input is what you would use if you were not using a cable box.
You should connect your cable from the wall to coaxial input on the cable box, and connect an hdmi cable from the hdmi output on the cable box to the hdmi 1 input on your tv and then switch the tv to that input.
Hello Jeff. I just have a basic question for you. Was the Blu Ray player turned on when you first plugged it into the tv? TV's are becoming so complicated that they are becoming less user friendly. Try setting your tv to the first HDMI input using your tv remote's input button. Then unplug the HDMI cable from the tv, make sure the player is turned on then plug the HDMI cable into the left most input if horizontal or top input if vertical. Hopefully if you do that and have the input selected, it should work for you. Also: Whi9le attaching the cable, I find it helpful to have it in a position where I can see the tv, because when a device hooks up the screen usually flashes or turns blue or something similar.
I unhooked the new tv and hooked up the old one to see what channel it was on and then rehooked up the new tv and put it on the same channel as the old one.This worked but I also had to put the cable into the hook up on the back marked cable instead of the one marked HDTV.
There is an input imbalance. Either try connecting your cables to different inputs on your TV, or try connecting to different outputs on your DVD player. (Only worry about the yellow video cable bit initially). Alternatively, try a different cable type; you'll have some ins and outs that don't use RCA connectors.
