Pixalization 4 yr old Toshiba 30HFX84. New problem with cable and DVD signal. Giant pixals (1" wide X 1/8") Acute on startup, then fading to slight with tube warm. Not present in menu interface or subtitles. Does this sound familiar? Bracing for the worst.

Could be the pixal setting on the tower is too high for the TV? Can you change the video card settings to the TV Pixal rating? You could have a bad video card. Good luck.

It is likely NOT the set and if using a box for hd it could be it.

Most likely is signal is slow and set cannot keep up with it.

You can't connect the PC to the 30HFX84 directly. (The HDMI ports are not compatible with a computer's signal.)

If you use a converter box (VGA to component video), you would be able to get the connection. See this site for some examples: http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html . Avoid the VGA to component video cables; those are for connecting to a projector that reads RGB signals at the component in.

Some video cards have a TV out option. In that case, you wouldn't need the converter. You might need the appropriate dongle to fit the video card TV-out and then connect the cable to the TV.

Crutchfield has the manual for the 30HFX84 available here: http://a248.e.akamai.net/pix.crutchfield.com/Manuals/052/05230HFX84.PDF .

I hope this helps.

You need to readjust your antenna and then reprogram your set.

It can be that the cable box is not as sensitive as the other box, try swapping the boxes. I had 1 of the three of my Comcast box replaced it three time (thay always replace it with used one which is a problem in itself, just lousy services), same problem as yours. Also check the cable connection to make sure they are clean and tight.

Sounds like pixal burnout unless you can correct through your desktop settings

The Main bd has possibly failed along with P-Logic bd. Have a trained Samsung tech troubleshoot the set.

Digital TV will do that when antenna does not receive sufficient signal.  You may need a different antenna or have to aim your current antenna differently. Go to www.dtvanswers.com for more info.

This model has been known for problems with the Hyper module but the picture would be affected with any input source.HD or not.The cable converter box and the cable signal are the only culprits for pixilation.Pixalation is the result of missing digital information via signal.If it is only appears on the HD signal I would suspect the cable signal or the converter box.I assume you are using your component input on your TV or the HDMI input.As a technician I would suspect the cable box or cable for pixalation.

it probably realted to a weak signal from source(antenna, cable or satelite box) if a direct source like a dvd player works fine its for sure your source.
