Question about RCA 20F512T 20" TV

Open Question

No Sound My RCA 20F512T 20" TV has a great picture, but no sound. We have checked the mute and the cable hook-ups. Is there a sound card that could have gone bad? If so, where and how do I replace? Thank you..

SOURCE: 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.

Sound went out


The problem is related to sound output section, or speaker. If the sound went out while working; speaker has out. Sometimes Ic related to sound output may be damaged. Some socket problems also may arise. If the picture is Ok the sound related problems are due the above said reasons.

Colours missing from tv


There are three color guns in a TV that make up the picture. Red, Green & Blue. It sounds like you have lost the green color gun.

You can get it rpeaired again, but your TV sounds like it is ready for TV heaven.

Green picture


a green screen on power up with retrace lines. At shut down a point appears in the middle of the screen. Sounds like either a shorted G2 grid, or bad flyback. If a phospher flake has shorted the grid in the tube, you can sometimes have luck by using a megger set at 1000VDC, to burn away the short. This is usually caused by the line HV going too high causing the anti-UV protection to kick in so fit a dummy load 40W lamp instead to the line output to allow measurements to be made.
