RCA D52W20 52 in. Rear Projection

yes or the green tube is going bad. if it holds solid just a little green, you just need to turn down the screen control for the green drive. if it gets brighter and brighter green until its really intense, suspect bad tube or board.

the green drive knob is hidden in the front, behind the front access panel. its labeled but hard to see, only turn the one know counter clockwise, it will be labeled G and SCREEN, there are 6 knobs

Almost certainly the green picture tube is shorted. This is a very expensive repair; probably not worth doing.

if it is a panasonic pt-50lc14 then you will need a new bulb. you can find them online, do a yahoo or nextag search for the ty-la 1000 bulb and you can find them for around $100...

try adjusting your color tuners located inside tv behind speakers.

replaced bulb green light continues to blink screen fails to light

Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off

my tv is 12 yrs old it started with the color starting to fade and then it started cracklin real bad and now theres no pic but there is sound

This will require tech repair.. the processor is dectecting problem. does the green light flash?

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.
