I began watching the Oscars and suddenly noticed that my viewing area did not bleed to the edge--there seems to be a black border around the screen. I thought it might be my cable signal, but the same thing occurs when I play a DVD. What can I do?

Re: picture does not bleed to edge
This symptom is caused by a poor regulation in the power supply circuit. too low dc supply voltage will result to insufficient deflection, both vertically and horizontally. black borders appear around the raster. receivers generally use regulator in the main power supply to set the dc supply voltage at the value that will allow the picture to fill the screen with a little overscan. defective regulator can result in a small raster. most modern receivers today are using ic (integrated cirduit) regulator. but if you are not inclined with this kind of job, better bring it to a qualified tv technician. good luck!

Google the model number with "problems" since this sounds like a damaged Optical Light Engine which has been burnt/damaged by the heat from the lamp and this is a common issue on this and other Sony sets.
The noise reduction option will cause a blur on fast movement. Also, you probably already know this, but a standard definition broadcast will look very blurry on an HD TV, so make sure the channel you're watching is actually an HD channel.
Oh, wow, I just noticed that this is from October. Oh well, maybe you're still having problems.
It's not your tv. It's your cable box setting. Go into settings on your cable remote and set picture size to normal and not zoom or any other setting. Also make sure your picture format is set to 16:9 on your tv. If you cannot figure how to change picture size on your cable box, contact your cable provider. Good Luck.
This can be caused not enough high voltage going to the picture tube. If the picture seems to get larger and smaller depending on the brightness of the scene on the screen that is probably what it is. IF that is the problem, there isn't much a normal consumer can do.
It seems your set has a loose conection in the high voltage circuits,in fact by now it should have many loose conections in different areas like the power supply and the horizontal deflection circuits,if you are familiar with tv service you can use the information as the first step to take,some of the loose conections are hard to see even for the trained technician but the one giving you this problem should not be hard to see,if you are not too familiar with tv service be safe and call for assistance from a servicer a least for an estimate.
