Question about Panasonic PT-D5600U DLP Projector

1 Answer

We have a Panasonic PT-D5600U DLP Projector, and the rear infrared sensor is not working. The front sensor works fine, but the projector is ceiling mounted, and we need to utilize the back sensor from the back of our church sanctuary. We need a parts list for this model before we can begin to troubleshoot the problem.

Hello: in most cases, front and back sensors are identical. Might even be those little boards, as well.
I've seen repeated problem with sensor board circuitry, not a IR sensor, itself. in my 2 cases, there was a faulty sms ceramic capacitor, twice at the same make and model of Phillips TVs. If you can handle safely open and close top part of projector's cabinet, you will see those 2 small pc boards, connected to control panel. To get a part#, go to "", then look for "support", then 'parts ordering". enter your model# and you'll find whole list of the parts for your set. You don't need any authorization to buy 2 little assemblies. Get 2! The other one will quit sooner or later! shouldn't cost too much, anyway.
Good luck,

Reset timer panasonic d6000

Have you bought bare lamp? Probably, yes. And not from "Panasonic"? yes. The timer's reset procedure is different for every model of Panasonic, including TVs. when you buy lamp with housing from Panasonic, they will give you the directions, how to. If it's "aftermarket", nope!
that's where you will find the procedure. it's quite complicated, page 45.
follow the directions.
good luck,

Just recently paid $836.00 for projector repair. Unit would not power ON, power indicator flashing 3 times. They said they replaced the DMD board. We asked to see the replaced part but they did not have...

If unit is working now, the repair is valid. Parts, like DMD are quite expensive and require core to return. Example: Main Board for Panasonic plasma TV cost $525+. When repair shop return a dud(core), they get $250 credit. Even some used parts, like light engine, require dud return(if you wish, of course) to get $50 back. So: now you know how it works. I won't blame them for immediate dud return, due to high cost of the part(s).
Especially for Panasonic. For the boards they require prior authorization. I've got into that mess couple times. Hope, that repair worked out well for you. If not, I might give you a second opinion, but I need to see and open your projector. It's up to you.

I have a Panasonic PT-D5500U. We replaced the lamp, and then shortly thereafter, whenever we turn on the projector the power lamp goes from green and shuts off and blinks red three times continuously. ...

the problem is a known "bug" by the manufacture, which is due to low temperature issue that's detected by the processor of the projector. it will require a firmware upgrade. i'd recommend getting in contact w/ their tech support.

Have a panasonic dlp 3yrs old, picture is very dark and hard to see in daylight. Ajusting picture in menue doesn't help. Have noticed a slow deterioration of pcture clarity.

It is likely to be a combination of things. 1) The lamp is getting weak and should be replaced. 2) The optical pathway needs to be cleaned.

Cleaning the pathway should be done by a professional as any slight movement will cause the projector to become misaligned. Depending upon the environment where this is used, this time period is within the norms for both lamp life and cleaning.

You may possibly find that running on duff lamps or lamps that are too old has killed the ballast unit.
Replace the ballast unit and fit a new lamp will probably cure it.
Hope that helps.

Replace the lamp assembly with OEM only! After you pull the old one and carefully install the new, you must reset your unit. The procedure should be supplied with your new lamp. Or, refer to owner's manual. Most likely, it will be inside of your new lap's box. Make sure, read it and keep in a safe place, after all. Next time you may buy "generic" lamp, but you will know how to reset.
Good luck,

Total Expected life (in hours) of a Panasonic DLP Projector

The projector lifetime has a lot to do with maintenance and environment. Over time, the LCD panels will start to deteriorate. I worked for a rental company where these units were in constant use. After 5 years, they were still going strong. Realize though, that these were highly maintained: constant cleaning via compressed nitrogen to remove dust, lens cleaning and filter changing on a regular basis. Checking for proper fan function and complete disassembly and checking for connections etc.

A word of caution: DO NOT work with the LCD block unless you have access to a clean area and have training. The tolerances here are very small. Slight changes can severely alter the picture quality and all adjustments should be left to a professional.

Hope this helps,

After a few min it shuts down just replaced lamp

There may be an overheated or bad capacitor in the unit. You can test with an ohmmeter to determine if there is a bad one. Do check ballast that lamp connects to for power with voltmeter as well.

My panasonic dlp makes a ringing noise near the side where the fan is located what could that be?

Replace color wheel assembly! Motor's bearings are gone. It will work for a little while, then will cease and destroy DMD board(part of light engine). Before it ceases, you may notice gamma is getting weird. Sooner, the better! It might cost $200, but it's doable for a skilled technician, if you never pull precise mechanical watch apart and backwards, try to hire professional. It's very easy to brake fragile color wheel, plus there are wires to be re- installed gently and in order, along with rubber gaskets.
good luck,
