Removal of Lamp Housing - Zenith DLP

I have loosened the two screws on the lamp housing/assembly but it does not slide out. The two black cords at the top of the housing seems to be the area that is holding it. Do these two cords "plug" into an outlet? I see some other screws in 4 recessed tunnels but I do not think this is the problem. My TV is Zenith Model Z56DC1D and the Lamp Model AS-LX50. Can someone share detailed information on the lamp housing removal and also the steps for the bulb replacement. I have the new bulb - just need some assistance. There are lots of videos out there but cannot locate the one that applies to my TV. PLEASE HELP ASAP!!!

Yes I have also been battling with this same lamp model in my LG62DC1DA for a few days now. The manual I have actually gives instructions but they are not for this lamp as step 4 states "Lift up the fixed wire handle on the lamp"and step 5 "Pull out the knob slowly and remove the lamp case".I do not see this fixed wire handle or knob it is clearly different.
From your description I have the same problem after loosening the 2 long screws, the assembly moves around a bit but does not slide out. I see the other 4 screws at the end of the recessed tunnels futher back but i think it would be a hard ask to remove these with out dropping them into the TV.
Yes the 2 thick black lamp wires do seem to be one of the problems. Like you I am hesitant to remove the back screws and cannot see how the 2 black wire can be detached.
Any help from experienced members would be much appreciated.:what::what::what:

Thank you for posting the photos. Yours is exactly like mine. It would appear we have to remove the screw to the right of the 2 black wires? But I don't want to do this unless one of our experienced Forum Friends confirm this is the correct step to take. Sorry - but you are "coaching" a woman attempting to do this - but I am capable if I have good instruction. I have already checked regarding re-setting the Lamp Counter - and I see no problem there. My current Lamp Hours are over 8,000. My lamp is not expired - but the picture is not very sharp and the light indicator states I need to replace the Lamp now. THANKS -

I also posted on another Forum to see if I could get some information. Below are 2 responses I got back:


"I just did the lamp change on my Toshiba 44 inch model which is an lg. 3 screws holding lamp and two for the plug.
turned tv on and got one red light and one flashing green...then shut it off ... turned it on and lamp came on ... just fine."



"I have the 52" model of this tv and when I replaced the lamp the plug that you see is what was keeping it from sliding out. It was very tight but was not screwed in, one good tug on the housing and it came loose."

Once I saw your last from the other forum I just jiggled with a bit more pulling force and out she came. I would not have done this before as you really think something is going to break, but the other posts gave me confidence.
Then you can see that the four tunnel screws hold a front metal holding plate with one side for gripping.Remove these after you have removed the top single screw that holds the two black thick wires to the terminal connection gate and poke the gate into the housing.
Grab the metal holding plate (screws out) and gently lift away and out from housing, the bulb is still attached.
Lay face down and remove the four screws at each corner of the stainless steele bulb holder.
Remove the wire at the rear of the bulb gently with small pliers and the other side wire with a phillips No 2 driver (small star).
There is absolutely no instruction anywhere on the net for this housing and bulb removal so I thank you for your patience and perseverance ..Rob In OZ:banana::banana::banana::thumbsup::thumbsup:I make a mud maps as I go to help with reassembly inc the position of the two wire terminal block in relation to which wires go where on the bulb itself.

thank you for your input. I just jiggled the plug and it came out. I replaced the Lamp using all the percausions (rubber gloves, etc) and reinstalled it. My Lamp came with a new cord, so I used the new one. My lamp cost $185 inc. taxes, shipping was free and I received it in 3 days. I ordered it directly from LG/Zenith - MCM Electronics. I THEN RESET THE LAMP HOURS - referring to the various instructions I had printed off. ONLY PROBLEM is the "replace lamp" message keeps coming on the screen. I have done the "resetting" 3 times. The Lamp Hours are reset to Zero so I think everything is okay - BUT DO I NEED TO WORRY ABOUT THE MESSAGE??? Does anyone know how to get rid of it??? During the process it asked for the PASSWORD. I used 0000 and it worked. I guess another is 1234 from what I have read. Again THANKS to everyone who contributed. Now if I could just "delete" the "replace lamp" message"!!!!
