Sounds like you need a fluid change on your blue cannon, or blue crt is out.

I have a Panasonic pt-44Lcx65 tv and it has this blue snowflake or blue star looking stuff all over the screen area and now within the last 2 weeks or so it developed this yellow or green large circle area...


Is the tv new? On which input is set your tv? Change some cables they are connected to your tv (like the HDMI) and see if you can get a clear image.

I have small blue dots and a yellow shadow in the middle of my screen


The model indicated uses what is called a Optical Light Engine, it is a very expensive part and likely is your problem---not much else will cause this trouble.

Let me know if you have questions.

Turn on goes blue then turns off


The most common reason for a TV to display a blue screen with no picture is because the source device has not been set to the proper mode.

If you are using a cable or satellite set-top box, ensure that it is turned on and set to an active station. If the set-top box is connected to the television using a coaxial cable, then the television should be set to Channel 3 or 4 to receive the signal.

If you have are using a VCR that is turned on, but not playing a tape and not tuned to a receivable channel, then a blue screen will be displayed on the TV. To resolve this, turn off the VCR or tune it to a receivable channel. If a cable or satellite set-top box is connected to the VCR using a coaxial cable, then the VCR should normally be set to Channel 3 or 4 to receive the signal.

If the blue screen is not because of a connected VCR or set-top box, the TV may require service.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!

Screen fades to blue.


The Blue SCREEN setting is too high. These adjustments are located inside the TV behind the front panel. There are two screws behind covers and then a wooden panel to remove to access the adjustments. The leftmost set are for BLUE, the middle are GREEN, and the right are RED. The top row are FOCUS and the bottom are SCREEN. Focus will focus/unfocus the tube and Screen will adjust the power of that tube (there are 3 tubes, one for each color). If Screen is adjusted too high, horizontal lines will appear (my TV had red lines, but I played around with the knobs and saw that it could happen on any of the colors). Additionally, if SCREEN is set even higher than that, the tube could go so high that it turns the whole screen that color (in your case, blue). If this happens the TV will shut down, probably due to either overheating or overvolting. To fix this issue, turn the appropriate SCREEN dial down until the lines go away. In your case, you want to turn the lower left dial down. Don't turn it too far down, if you turn it more than necessary the TV can give you an AKB error (noted by the STANDBY light flashing a sequence of 5 blinks).

Disassemble Rear Projection TV


well the short answer is : Check the sides of the set see if there is a crack in the middle where you could separate them
Long answer: i would not recommend it even if it does, the screens are sensitive and could get dust inside the screen.
Never taken one apart that far. i suspect most tech don't because of the problems aligning and dust ect.. trying to get it back together.
