My picture is dull and fuzzy. Could it be because I added coax cable?

[stupidugly]

I recently had the installers come and install a slim line dish on the roof of my new loft. The distance from the roof to the ground floor is about 35feet so the cable is really long. I didn't notice at the time, but the installers didn't leave me enough slack on the cable to move the TV anywhere other than where it was. I went to the home depot and bought 2 rolls of basic coaxial cable. When I patched in the coaxial cable the picture came back on with no problem, but now I feel like the picture isn't nearly as sharp and the colors are not as bright. The HD quality is not what it was before the move and I'm wondering if it could be the cables. Is there such a thing as low quality or high quality coaxial cable? Can this be what's affecting my picture? Is the cable not quality enough to pick up the HD digital picture? Will I have to have them come and re-install? I have a brand new HD DVR by the way.

Thanks

Nah, it's a digital signal from ODU to IRD. If it gets there the PQ will not be affected.
Are you sure you are using the HDMI input and also check if you are not using any sort of ZOOM function on the TV set.

There's a 95% chance that the PQ degradation is coming from your placement of the TV itself and has nothing to do with your satellite cabling. The remaining 5% is tied up in damage to or calibration of the TV as a result of moving.

You should check the signal levels on various slots to confirm.

What display technology does your TV employ? Large CRT based TVs can be negatively impacted by changing the direction that they face.

My TV is a PDP. I moved the TV no more than 5 feet. I had it against the west wall, almost in the corner where it meets the north wall. I moved it to the north wall about 3 feet from where it meets the west wall. Could that short a distance mess it up that much?

It only happens on certain channels. The only channels that seem unaffected are the HD movie channels. Those are bright and clear. Channels like ESPN HD and FSN HD are a bit blurry and the colors are dull

Make sure its not RG59 and if its RG6 make sure it is rated to at least 3000MHz (3GHz). Not all RG6 is the same in capacity. Cable companies like Comcast use "Britewire" brand RG6 which is only rated for 1000MHz (1GHz), this will not work with Satellite TV. Although you probably wouldn't even get a picture with the wrong cables. Also, if you put the cable ends on, be sure you crimped them on properly.

Comcast uses Comcast QuadShield, not Brightwire. Brighthouse uses Brightwire and is rated to 3ghz.

It is digital to the receiver, so either it will be pixelating/not get there at all or work as it should.

Check for power lines in the vicinity. Plasmas are especially susceptible to AC lines. Also make sure there are no fluorescent lights in the area. Those can also mess with a plasma.
