Hello,

You have the classic "blue blobs," In most of Sony's rear projection LCD's, the Optical block is bad. Manufacturer's defect. The blue panel inside of the optical block starts de-laminating (due to heat from the lamp). This is a very common problem. I have changed about 70-80 optical blocks myself over the course of about 4 years.

There is no other fix but to replace the optical block. Unfortunately, it will get worse, and will probably develop "stars," or stuck pixels, as well. You can call Sony and try to get some assistance, but the extended warranty on these sets has recently expired.

Hope this helps you in some way...

How do I use my craig CLC503 TV as a computer monitor.When it is attached to my Dell computer it shows windows xp starting up but then the screen turns blue


the resolution of the laptop screen is set to high for the tv to show, on the laptop screen right click near the middle of the screen and goto properties at the bottem, the displdy properties window should appear, click on settings on the far right, a slider at the bottem left of the window controls the reolution, pull the slider to the left with the mouse cursor to the setting 800 by 600 pixels also the box on the right that says colour quality click on the arrow that should be pointing downward and set this to 16 or 24 bit, once done click apply and ok. shut down the laptop reconect it to the tv ensuring that the tv is on the correct channel and restart the laptop, you should now have the whole screen on the tv. good luck and hope this helped.

i am not sure these is going to work but give it a try. after useing the tv for a long time you can get a problem with the lineing of the three picture colors may drift away from each other causeing the problem you have, they move because of moveing the tv or the viberation of the tv.  you can to one of two things if you have a remote for the tv go to the menu and look for the convergence adj. setting then you are going to get close to you tv and press the small but the says the same thing now on the screen you are going to see a grid the you can fix youself with the remote just by pressing the up, down,left, rigth buttons and the menu button to change the color, to aline the red line and blue line with the middle line till you get only a white line going up and down  if the doesn't work just unplugg th power cord and what for about 4 hours and then plug it in and turn it on again. if after you do all these if you still have the problem then you either have two choices call to see how much it will cost to repair it or toss it out and get a new one

Picture has a blue shadow


Hi,
Seems convergence out IC is fried in TV so it gives blue shadow.

Check out Convergence Out IC which you need to replace in TV, if you have enough experience of repair of big TV, necessary tools and know basic electronics.

Blue wide streaks in my 42" Sony TV model KDFE42A10.


I have the same TV and the same problem and it's also just over 2 years old (bought it June 2006) when the problem started. Every day, I saw the blue streak cover more of the tv, now 6 months later, it has all turned to green and the entire tv has a green tint. It looks like I am watching tv in murky green water.
I am lucky that I purchased the additional warranty on the tv and finally got around to calling them. I hate to tell you this, but they told me that the optical light has gone up and they are replacing the tv.

Blue streaks across picture


Can you describe in a little more detail what the symptoms are? Are the streaks thin lines or are they large thick swashes of Blue? Is yur video still visible? Sounds like it may be the blue convergence amps or the resistor tied into the amps. is there anyway you can post a picture of your screen distortion?

Blue Streak


I had the same problem w/ the same TV about 6 months ago. You need a new optical engine. Hopefully you are still under warranty. Once that was replaced, the tv looks great.
