Question about Projection Televisions
I have a Sony LCD rear projection TV (KDF-E50A10) manufactured in November 2005. I use a cablecard with Verizon FIOS TV. According to Sony, the TV has the latest firmware.
A few weeks ago, I noticed pixelation on local HD channels only. According to Verizon, no one else in my area is reporting this problem. The pixelation does not occur on any other channels, and occurs at any time of the day or night. Verizon has replaced the cablecard, the Optical Network Terminal, the cable from the ONT to the TV, and adjusted the attenuation levels to the proper level (0 db). They checked for ingress, but found none. The pixelation continues to occur on the local HD channels.
As an experiment, I removed the cablecard and let the Sony tune in any unencrypted channels I was getting. In this setup, I am still able to tune in the local HD channels via cable. Again, the pixelation is present.
A Sony service center tech said that in his opinion, the problem lies with the signal. Verizon can find nothing wrong with the signal coming to the TV.
I have attempted to isolate potential sources of signal interference in the house, such as cellphones, a wireless router, cordless phones, refrigerators, etc., without success.
Any suggestions appreciated.
MY Sony (same model) has OUTstanding picture resolution and quality., I never have blockiness on any of the sports channels. I would say, give Comcast a call and complain about their signal.. they have a tech come over for free diagnostics on your wiring..

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.

SOURCE: Is it the TV or Comcast?
I'VE SEEN QUIT A FEW SAMSUNGS DO THIS AND THE DIGITAL BOARD IS THE PROBLEM YOUR MODEL NUMBER DOES NOT HAVE A DASH HLR4667W AND YOU NEED YOUR VERSION NUMBER AND MAYBE THE BEST THING IS GET THE PART NUMBER OFF THE BOARD.

OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!
Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.
1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.
I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!
