Got this projector as well as another DP PJ that have the same issue. Both have solid amber/orange standby LEDs upon plugging them in, the user manuals say they are ready to power up in that state, but pressing power on the PJ does nothing, nor do any of the other buttons. It just sits there in standby. The same goes for when using the remote (I do not have the original, but I do have a Harmony 1000 that has the codes for them), it does nothing to the projector.
Since these are rather high end, information is limited for what I could find. I'm wondering if theres something I am not doing? Any help appreciated! (These should work once I get them to power up)
Edit: I would just like to update and let everyone know the projector is now working. After replacing the missing crystal & resistor on the mainboard, the projector is once again working perfectly!! (See last post for screenshot)

Please clarify this. I am not seeing is description in the manual.

Please clarify this. I am not seeing is description in the manual. The manual says: "Permanant Yellow Light (Which its more of an orange/amber in real life): The unit is in standby mode; no sources connected; or the sources connected are inactive/switched off, thereby activating the power-save functions (DPMS). You may enable or disable the power-save function in the SET UP sub menu, DPMS on or off." Which is exactly what it is doing, sitting in standby laughing at me  Now another part of the manual says any buttons not illuminated on the unit itself are deactivated. If that's true, then all the buttons on the projector will not operate. I suspect the possibility the projector may be "locked" with a PIN number. Unfortunately, the manual does not tell you how to enter the PIN while the projector is in standby, or how to power it up if its in this locked standby mode. I have the default PIN which will probably work, but again, not sure how im supposed to enter it while the projector is off and unable to be powered on? I'll be honest, I haven't wasted my time contacting DP about it, as I'm sure they will want to verify I'm the original purchaser (which of course I'm not... when this stuff comes in as surplus you are SOL...), and then say they can't help me because I don't have proof of ownership *eyeroll* Like I said, if I can get these damn things to power on, they should work (verified the rest of the components work by swapping mainboards from a working unit), and I doubt the mainboards themselves are bad. |

Ok, there is the problem. You are using color descriptions that do not exist. You must indicate colors based on what the manual states. otherwise, I have no idea. Second, I have to assume you are talking about the "status" light. You did not indicate this either. Again, you must be more accurate in your description. LOL  Now based on how I am reading the manual, it will only go into DPMS mode if: 1) DPMS is set to on, and 2) there is no input signal when set to on. Have you tried connecting an input device, have it running and then plug it in? Next, manual indicates when first plugged in, "status" light should blink yellow for app. 10-15 seconds and then become solid yellow. Is this what it does? |

Yes I see I made several errors in my posts, my bad I was referring to the status LED  I connected my computer via DVI cable and it did detect the projector, but the projector was still in standby, would not power up. And yes, when plugging in the power cord, the status light blinks and then becomes solid yellow. That is the extent of life from this projector. Also, I can connect a ethernet cable to it, and the LEDs on the ethernet plug light up and blink, so it connects, but its IP address is not the same as my network, and obviously unless I get it to turn on, I cannot change that setting. So ethernet is useless |

Have you opened it up yet?
Have you thought about downloading the control software and seeing if you could get it to connect?

Yep - I opened it and swapped in a mainboard from another one identical to it that I have here (working) and it works fine with the working PJs mainboard, just not its own. And yep - if you are referring to the control software that was on the support page for this PJ, I did download it, but it did not work (even after carefully repeating the steps to get it to work) This was the LAN control that I am referring to. I have not tried with RS232 (have no idea how to go about that without a PC that has RS232...) |

Can you post a nice clear picture of both sides of the main board?

Can you post a nice clear picture of both sides of the main board? Sure can, sorry about the delay, this weekend was pretty busy. I got the projector partially taken apart right now so I'll get a pic of the mainboard shortly. It's not in an easy to access place (mainboard is the back button/input panel as well) |

Already have an update, and 99% reason why this PJ wont work. I didn't notice this the first time swapping the board, but I wasnt really looking around.
There's a power connector like a mini ATX Motherboard PSU connector on the DMD board, the connector pins are pulled right off the solder pads and only one is holding it on yet. I only noticed it now because I bumped the wire and saw the connector move. I'll post a pic of it shortly.
I don't think the mainboard was the issue at all though now after seeing this. It's quite likely it was ready to break off when I put the other mainboard in and got the PJ to fire up. Must have just been held on enough to make it work intermittent, but its not held on enough anymore!
Always something new!

I am curious to see what the outcome will be after repair.

Well, my sureness bit me in the ass it would seem! The power connector is repaired and went pretty smooth, but it still wouldnt come out of standby. I pulled the mainboard out again and this time I noticed something else (Look at the center of the photo) :  There are pieces broken off the back of the mainboard, which I am *mostly positive* is the cause of the problem. Now I looked at my good board and they are almost identical except for some of the circuit design. (They physically can be swapped between projectors but they are slightly different variants and as a result not 100% identical. [Good board does not have HDMI, bad board does) I could probably repair it if I knew what the missing crystal frequency was, and the missing micro capacitor/resistor is. Without the SM or a 100% identical board I don't have a clue. |

wow. Nothing loose shaking around in the projector?
If you can id the ic that the crystal goes to and if there is a data sheet on it we may be able to determine those parts.

No, nothing loose inside the projector when tipping it upside down and shaking it, so my guess is whoever broke the parts off in the first place is likely the one who cleaned them out too. I will try to locate the IC and see what I can come up with.  |
