Slight distortion of color on screen

Hello. My issue is found on the almost left bottom portion of the screen.There is a slight color distortion at an individual spot, about a foot in diameter and primarily is noticeable when showing a green background ( like golf ). It is localized and seems to be getting worse. Any thoughts as to cure or what the problem is? The tv has been excellent so far other than this. Firedog

    I've reset to factory settings as suggested but the problem still exists. It appears to be physically in the screen, like a picture with a blemish or overexposure. I wonder, would the bulb becoming weak cause this?

I have this same problem. This is caused by a defective optical block. Sony currently has extended coverage on optical block replacements, but not for the symptoms our tv's display. After several phone calls, I was told they would cover replacement of my optical block (a $1000 part by the way), but I would have to drive it to another state to one of their certified service centers. Once it was there, they suddenly decided to NOT cover the block as promised to me on the phone, and conveniently told me although my block was defective, that it wasn't the right kind of defective. So I was left with wasted time, miles, gas, and a diagnostic charge for an unfixed TV. visit http://splinke.googlepages.com/sonyrearprojectionlcdtv-opticalblock for more help.

Blue spot on screen


Hi. this is called convergence failure. the convergence board is a circuit board that regulates the RGB(RED BLUE GREEN) streams that make up the color picture. If the convergence board chips are malfunctioning, you will see a distorted view of these RGB streams. This is what you are experiencing at this time.

Simply replacing the convergence board or chips will fix this issue.

Please rate and have a great day:)

Infocus SP4800 Distortions


with the image shown, use the lens to focus on the spots. if you can, it is dust. if you can't, you have a colorwheel issue. to take the top off: remove the 8 screws on the bottom (4 brass from the bottom middle, 2 silver from front bottom, 2 from rear bottom), 2 or 3 on the back. use a small flat-head screwdriver to undo the clips through the top vent on the back panel and remove the panel, unplug the wires fron the left and right sides, pull the top up and forward taking front with it. blow dust out with dry compressed air.

You have a convergence problem. Here are some of the most common symptoms.

One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

Uh Oh! blue screen of death. Your light engine has warped a little from overheating and is distorting the picture.

My suggestion to you is to get on the phone with Sony and start complaining, then keep complaining until they agree to pay for it. Even if it is out of warranty.
You may have to get the problem diagnosed by a pro before they agree to pay for it though.
Hope ya fix it!
