When tv is first turned on the picture is fine but after a few seconds the whole screen becomes a blue covering the whole picture. If tv is turned off and turned on a few seconds later the picture comes on then gradually becomes blue and covers the whole screen like a thick fog.

projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.
Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
The blue picture tube has gone bad. Sadly they are no longer availible for that unit. But the blue tube assembly can be sent back to a company called Video Display. They rebuild the tube for a very reasonable price. The hitch is that it takes a professional tv tech to reinstall and align the rebuilt tube. Most respectable shops will do this work but the repair is spendy. Usually around $450 to $500 or more.
Check the info from this website to see if you are able to fix your TV. You should turn the blue screen control down slightly counterclockwise. If that did not work, then more likely you have a video amplifier IC defective or a blue CRT.
Sounds like you have a problem with the blue gun in your picture tube or its drive circuit.
You might remove the back cover and gently tap on the neck of the picture tube using a plastic
screwdriver handle while watching the screen in a mirrow. If the picture flashes back on or on and off then the picture tube is the problem.
If this is a projection tv you have three separate tubes : red, green & blue.
you'd need to tap the blut one.Gently!!!!
I'm about 90% sure it is the blue picture tube developing an intermittent heater to cathode short. I'm surprised the set isn't shutting down shortly after this happens. A service call will tell you for sure as it could also be a bad solder connection causing a similar symptom. My own procedure to check it out would be to GENTLY tap the neck of the suspected picture tube with a screwdriver handle to see if I could get it to come and go (Or get out my CRT tester and measure it with the power off). Obviously by holding the screwdriver blade you don't want to accidently short anything out as there is about 33,000 volts a few inches away from where I would be tapping. Nuff Said.
