I have a Sony 47 inch rear projection tv that is about nine years old When the set is turned on it has a good color picture but after a few minutes it tuns to a complete green sceen. Can you tell me what...

The green CRT may be intermittently bad or the focus screen block. Certain sony's are common to have bad CRT's. When the screen goes green does the set shut 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.

Green horizontal lines on screen no picture

The green CRT's (color picutre tube or color wheel, or ballast) will need to be tested for replacement.
It is quite common with these tv's

You will need an ohmmeter and or voltmeter and test each component for currency and accuracy

Projection tv 42" panosonic hdtv. to much green in the picture. Jeff

this unit may have a resistor on the green crt-board that has increased in value. check ohms(resistance) on all crt boards and compare to one another. these will have color bands that inicate value of resistance. you do not need to know color code, just match colors of resistors on each board then measure. you could also have weak green tube. turning down the master screen control located on the fous/screen block can reduce grn. drive. to adjust proper drive for each so the grey scale is correct, turn color to tv all the way down then adjust screen controls on block for black & white picture. when color is turned all the way down, you should not have any green, red, or blue over cast on screen. mch

RCA 52inch TV

If the screen control for the green picture tube is set too high, then the colors will be greenish, there will be green where there should be black and there will be fine curved lines (retrace lines) in the picture. If you feel confident then you can open the set and look for the focus block which has the 3 focus and 3 screen controls. One row is labeled Screen and the green control will be the center one. Try turning that control down a little and see is the green background and curved lines go away. If they do not go away then there is something more serious wrong. If you do not have experience working on projection sets then allow a qualified tech to handle it for you.

Problem with color

Yes you have a problem in the red crt driver board. Most likely the driver transistor is failing. This is a component level repair, so if you have no experience with TV repair, play it safe and call in a trained tech to assist you in this matter. Good Luck
