How can I upgrade my cable box to HD without buying an expensive package from my ISP?

SOURCE: Sony BRAVIA KDL46S2010 Sound and Pix not in sync - in HDTV channels only

This is a software issue with both the TV manufacture and the cable box provider. This will only be fixed when the cable company and TV manufacture sit down and work out their problem. Some cable company has taken the first step by updating cable boxes with different software.

I JUST BOUGHT A HD SONY BRAVIA TV. IT WAS OKAY FOR A WHILE AND THEN ALL OF OF SUDDEN THE CHANNELS ALL BECOME BLURRY. WHY AND WHAT SHOULD I DO?

40X2000, both PS3 and DVD player are using a HDMI input and both flicker and loose signal fully, have to turn TV of then back on to get signal back. Sony say they have never heard this problem and replaced board. NOTHING fixed, still same problem.

SOURCE: TV not finding Digital Channels from Cable Box

We have Comcast and we plugged the cable straight into our Bravia, searched for Digital Channels and it found 131. We actually get all the HD channels that we had using the box, plus a few more. It's worth a try.

There is nothing wrong with you Sony Bravia TV and it suppport all HD and SD formats.

Are you viewing the HD version of the channel when it is showing a standard defination show. e.g SKY1 HD instead of SKY1.

This means that regular standard defination shows are in a 4:3 ratio and does not fill the whole screen. In order to view these type of shows you will need to tune to regular channel instead of the HD version.

You can check if a show is brocast in HD by going into the tv guide and checking for the HD symbol in the programme symposis.
