On my set, green lines appear on the screen and I was told that the green lamp/tube would need to be replaced. I have been getting te run around after the repair guy repaired the shutting off issue for $200. He is also saying that I will have to pay again. It's been weeks. What do I do?

SOURCE: Realistic Lamp Cost ??

139.00 seems reasonable for a replacement lamp. is that the only problem that you are having or are you hearing a squealing sound and then the tv cycles off?

SOURCE: whining noise on start up, lamp and TV shutting down

The TV tech isnt too familliar with RCA TVs. The color wheel is the most likely problem no where near 1000. Depending on the model number of your set you can get replacement color wheels at the following link.

Changed crt coolant, better picture. red squiggily line starting at top center of screen, runs about a third of the way down. thought i saw scratch or small crack in green crt "c" lens. would this cau

Sounds like you may have just left one of the wires loose from the red tube. Not likely an issue from the gren tube but you can always cover the top of the lens and let just green shine up. That may help narrow it down also.

Here is more detailed info for you also.....

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.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.

I posted a problem on how to remove panel but I solved it. Now as I mentioned the tv comes on goes green then black no picture just sound. I followed instructions on adjusting G screw but it doesnt work...

Its possible one of two thing have occurred, you have maladjusted the G screen control on the high voltage screens and focus assembly. Turn down (counterclockwise) all three of the screen drivers. Adjust each until a light appears in the each lens, red green and blue. Go slow or lines will appear if set too high. If all three lamps stay lit after this adjustment the look at your screen with color level down to zero using your remote and the picture menu. Adjust the three color drives to get a good black and white balance appearing on the screen. Now adjust the color level from the picture menu back up to normal range.
If you still get green diagonal lines after this adjustment then I would suspect that the green lens has a heater to cathode short in the tube.

My screen has little dots appearing sometimes red sometimes blues behind the picture i just replaced the lamp bulb as i thought it would cure the problem

the projection tube needs to be adjust for color alignment, each tube (red, green, blue) must be aligned so you there would be no color smear appear on screen. if it is aligned try to set up the color balance, hue etc.

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.

Sony kp-57ws500 green screen then auto shutoff

I have the same tv and it did the same thing only now it has red hues all around the picture as well. The service guy told me it was the green tube and it would be about $500.00 to replace and may not fix the problem. What a p.o.s. I will not be guilty of buying any other Sony products from now on.

SONY KP-46S25

A "Gray Scale" adjustment may solve you problem. If one of the picture tubes is set too high it will cause these RETRACE lines. Then too a weak picture tube might cause this. If the horizontal lines are one color: red, green,or blue then whichever color that is shown would tell you which tube is set too high. Your set has 3 screen controls that control the brightness of each tube. One may need to be turned down a little. Stargazer

Lamp issues

No its a tube and not a bulb. If thew line is green then theres an issue with the red and blue as the green is stationary on most sets unless thers a green centering ? Its a componet on the convergence board thats bad or going bad but if you replace any components on the board most likly your gonna need to do a convergence alighnment I would let a pro handle this repair unless your an experineced repair tech Good Luck
