I have a sony kp-53s15 that is having picture problems.The pic is jumping,lines, blurry,and is pic is not all the way to the sides.The sound is good but the pic isn't.What is going on?

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms

• Screen Looks 3-D
• Colors wont align
• Screen may look distorted or warped
• No Audio/Video - makes a chirping sound.

Problem #2

Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

• Dull looking picture
• White looking picture
• Halos around objects
• Red/Orange looking picture

i have a sony rear projection TV, model number kp43t70 screen went black and there was still volume but no pic so I turned it off and now won't turn back on

If the picture is bowing in on the sides, this is called a pincushion problem. Please confirm that your model is KP-53XBR45 and I'll look up the probable defective parts.

Did you accidentally turn on SVM? Make sure it's off. And make sure you haven't switched to a different picture mode by mistake.

It sounds like you have a bad I/O board. That's the input/output board that everything plugs in to.
