My tv has a series of evenly spaced dots on it that run from right to left across the screen. The dots are easily seen when close to the tv but are not noticable when you are 15 ft away. The dots are multi coloured and usually travel at the same speed across the screen.
I am hooked up to a satelte system. My cable from the tv to the satalite dish is 75 feet.
I am not sure of I have a tv problem or a reception problem?

First off what type of input are you using going from the ps3 to the tv. If your using HDMI try changing the different video settings. Black ops actually has a lot of problems right now on ps3. So I wouldn't use that as the basis of what is working or not, I would try other games to see if it's working. Adjust the video settings on the ps3 and see if that helps. If that doesn't try using component cables and see what that does for you. Thank you, Lee
Replace it if you want true HD. The TV has 640 × 480 pixels (dots) in use for 16:9 or 852 × 480 dots for 4:3. This translates to 480p or SD resolution.
You can watch an HD signal with downconversion. You will also need a digital to analog converter for OTA signals since the TV doesn't have a digital tuner (ATSC in the US) It reads NTSC, PAL, PAL60, SECAM, Modified NTSC signals in the following formats: 525 (480) / 60i · 60p, 625 (575) / 50i · 50p, 750 (720) / 60p · 50p, 1125 (1080) / 60i · 50i · 24p ·25p · 30p · 24sF ···· SMPTE274M, 1250 (1080) / 50i.
I think I have a good idea of what you're experiencing.
Our minds are so set in the low-def mode that when those extra lines are filled in for high-def it looks like a bunch of dots. Notice everything is so much more clear? I thought the same thing when I watched my first blu-ray disc.
Watch something in high-def and then go back to standard immediately after. You'll notice that you can't get near as much detail off of the low-def.
Those dots are your mind trying to put high-def into low def.
Hope this helps; please rate my solution accordingly
Does this help A standard video signal is actually a series of still images, flashed on screen so quickly that we believe we are watching a moving image. The typical frame rate used in North America is 60 frames per second (60Hz) meaning that a TV would display 60 individual still images every second. Sub-field drive is the method used to flash the individual image elements (dots) on a plasma panel. For each frame displayed on the TV the Sub-field drive flashes the dots 8 times or more, meaning that the dots are flashing 480 times per second (480Hz) or more. (Example: 60 frames per second x 8 sub-fields = 480 flashes per second).
NTSC is the earlier and soon-to-be extinct US standard, ATSC is the coming one for HD and is digital instead of analog in its signal coding.
Most later sets will determine what is available and switch accordingly.
Many stations are running tests at random now for a few minutes to let you know if your set is HDTV 'ready.'
Check with your local station schedules to see if they are listing times for this test signal.
