With the symptoms id start looking in the High Voltage area for a Multiplier block failing or possible fly back transformer and i would not continue watching it ti the problem is isolated and repaired as this can further damage and destroy a video processor IC or other parts but id suspect a multiplier block or high voltage tripler is another name for it it is its accesable from the front by removing the speaker panel and be CAREFUL as there is High Voltage present there and you could get a Nasty Zap

The screen is green no color at all it makes aloud humming sound what is the problem we replaced the lamp last year


Do you have a cable box going to the TV and is this condition on all of the inputs or just one. Chances are you have standard video connection plugged into the component inputs.

If you have a (yellow/red/white) cable make sure you have it plugged into a connection on the tv that matches those colors because if you have a standard video (yellow) plugged into the Green then you will get a black and white picture.

If you are plugged into a component connection you will need a total of 5 RCA style wires. One will go from Green to Green, another from Blue to Blue, another from Red video to Red video, anther Red audio to Red audio and white audio to white audio.

The common mistakes made with this connection is the reversal of the RED video and RED audio which will cause the humming noise you spoke of as well.

Thanks,
Robert

experimenting a color wheel problem.The

color wheel is a rotating disc that has a

gamma of colors it spins at high rpms.The

light of the lamp goes through it to create

the colors on your tv.When it starts to go

bad you will hear ,humming,buzzing,high

pitch noises ,you might also experiment

color distortion ,black and white

picture.Here's a link that will help you

replace it:

Install new lamp, nothing comes on ,change back to old lamp still nothing


Hi,If the lamp didn't do the work it could be that the problem is with something else.If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Do you hear buzzing or high pitch sounds? If you do it could be a problem with the color wheel.The color wheel is a rotating disc that has a gamma of colors it spins at high rpms.The light of the lamp goes through it to create the colors on your tv.When it starts to go bad you will get color distortion ,black and white picture and sometimes you will hear humming noises.Make sure the door cover is properly shut other wise it wont lamp light up.
