    Actually not shaking, but flashing.
    It started flashing when the fan behind the lamp is on.

I have a panasonic pt-60dl54, the sound works but green picture


Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.You will need to replace the DMD board. Have a blessed one!

TV made a big popping sound, and then a crackling


Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php That crackling sound could be of 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. But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs it could be time to replace the lamp.The lamp you need is BP9601073A you can find original here:http://www.discount-merchant.com/Samsung-BP96-01073A-lamp-p/samsung-bp96-01073a-lamp-oem.htm?Click=48173 .Have a blessed one!

Green screen


inside the light engine there is a red a green and a blue glass color filter.The heat from the lamp causes the color to burn off the glass.You need new filters .One is red one is blue and one is green.The lcd itself doesnt make the color,it is a black and white device.The colr comes from light shining through colored glass

Replaced LCD Inverter, now screen comes on and bright but choppy


Does the external monitor display a normal image?
If the images is OK then the video card is OK.
The inverter supplies high voltage to the CCFL lamp which provides the backlighing and does not jumble the colors on the screen. If you get a pinkish hue or a flashing screen then this would indicate
the CCFL lamp is faulty.
From the description of the fault, it indicates that the fault could be a faulty video cable or video connector. Try reseating the video cable/connector on the motherboard.

Dark band at top of screen...now whole screen


Pop sound is probably the Lamp or maybe the color wheel. When you unplug and try it on do you hear a whirling or winning sound ? Is it followed by a slight ticking sound ? If you get the whirling and a ticking sound it's probably a bad lamp. If you don't hear the whirling sound you may have a bad color wheel. The parts are both made of glass. The pop you heard was one of them breaking. If you can't tell, order a lamp you will need to change it eventually anyway.

My screen is black but i ges sound then the red


Have you checked that the lamp is working? If the lamp hours are too high, then the television will no longer function until the lamp is replaced and the counter reset.

When you have replaced the lamp, do this process to reset the timer:

1) Press the Menu button
2) Scroll down to the LAMP TIMER RESET option, scroll right to enter
3) Confirm that it is OK to reset the lamp timer by hitting the OK button.
4) The on-screen menu should confirm the lamp was reset correctly.

I heard a pop and now the projector only shows black and white.


The color wheel has failed in youtr projector. There are 4 pieces of glass in the color wheel which fit togeter in a "pie" formation and they are red, blue, yellow & clear. This wheel is spun by a motor. The glass is glued to the motor's hub, and, when it fails the glass segments are thown off the hub. This gives you a B&W picture because all of the light is allowed to shine through the optics all of the time. Replace the color wheel with Toshiba part no: 23125963. It will be about $65. No soldering is involved, just use care with the ribbon cable to the motor. You will need a no. 2 phillips screwdriver and a set of jeweles screwdrivers to do this.

BLACK AND WHITE SCREEN AFTER AN HOUR


This is usually caused by the tuner which loses the chrominance part of the NTSC signal. Your did not say how you have it connected but it you try using a composite video input (yellow jack) and get the color OK than it must be the tuner which is not cheap but is worth having replaced.
Hope Ya Fix it!
