Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

Green picture only


The projection TV has 3 guns RED GREEN BLUE. In your case the red and the blue guns are gone. So you are getting the green color screen. You got to replace the picture tube.

Philips 23PF9966/37 color problem!


Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

TV picture is red.


Normal color picture is composed with 3 colors R-G-B (Red-Green-Blue). Picture turns Red means: Missing Green and Blue colors (many reasons: bad contacts, projector tubes dead, and other...). Try to give some "tabs" to diagnose ... I don't know what is the type of your Projection TV, how long you owned it, to have more idea.

After a few minutes the color goes to intense red and green


My tv didn't turn green, but the red separated significantly. It started off happening after a few minutes of being on (I suppose the defective part was "warming up"), then it got to where it was like that immediately upon turning the tv on. In my case, I had to pay a tv repair man $350 for a new part. There are 2 microcircuits that control the color alignment--one that controls the red only, and the other controlls the other 2 colors, blue and green I believe. Maybe your part is the blue/green controller, mine was red. The repair man said these parts fail so rarely they don't stock the part. The cost of repair may be different for a different part, but either way you have to choose if it's worth that cost to you. If you get rid of it, I'll buy your tv stand ;-), I bought mine from a friend and didn't get the stand in the deal.
