I pull the original bulb out and look inside the socket where the electrical connection is made between the bulb and the television. There is nothing there!!!!!! With my flashlight I can see that the connector from the TV is hanging loose and cocked at an angle. The only way to find out what is going on is to partially disassemble the TV. I take the lower back off including the fan cover on the lower left side. Under this cover is a metal plate. It looks like it might be an RF shield. I remove it partially all the way from the left corner to partially include the connection panel.
After removing this and pulling the RF shield away, I can see this little piece that have at the top of the page was what held the electrical connector on the TV side in place so the connector on the lamp assembly could slide into it. The little tines was all that gripped the TV side connector and held it and either by design flaw or excessive heat, it had warped enough to loosed and allow the connector to fall back inside the TV.
The solution was to install the lamp assembly and screw it down firmly with the thumbscrews. Then go too the back of the TV and push the TV side connector trough the hole into the bulb side connector. It wasn't a pretty sight but it worked!!
Buttoned it all backed up and I'm now back in business although I did end up with a couple of extra screws.
By the way, the new bulb did amazing things for my picture quality. Whites are white again and the blacks also look blacker. Even my wife who really doesn't care and thinks I'm a little nutty commented that the picture looked much better. The original bulb was an OSRAM and the new bulb was an OSRAM. However, the difference is really like night and day!
Sorry for the long post."

This is his picture of the little piece that fell out:

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!

This could be a faulty CCFL lamp.
To determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

DLP TV starts to loose picture after 1 - 1/2 hours of use


This tv has a 3 board video path. Analog main pcb --->Digital main pcb --->DMD pcb. see which inputs have the problem to narrow it down. if only some inputs, suspect analog board. if everything flickers(all inputs and menu), suspect the dmd or engine. you can see the lamp shine out the back. if the lamp is flickering, suspect lamp or ballast.
