NEC VT47 lamp won't light

I have the same problem. Beeping, the green light goes to red, and the inner air is wery moist.

After a few minutes it resets, and it works fine again.


Any suggestions ?

Hi Brent, Mitsubishi's have a problem with the power supply and the Light Engine which incorporates the Digital Module of which it has to be purchased as a complete assembly. I sincerely believe you should not put that kind of money into a dlp set. The cost of the light engine is in the area of $1100.00. Your last idea is the best one.

Check the lamp and color wheel.

Try pairing the parent and nursery units again. First, turn off all of the units. Place the broken parent unit within 5 feet of the nursery unit. Turn on the parent unit. Turn on the nursery unit. Within a few seconds, the top 4 green LEDs should shut off. Then you'll hear a few beeps and the connection LED should turn from red to green. If this doesn't work, power off and try again using the AC adapters instead of battery power. I did it without plugging in the parent unit but the battery died as soon as the units paired up again. It's working fine from the docking station though.

Annoying! happens to us too frequently, but this works. We ended up buying a new one and returning our broken one after owning for three months From Manual:) 5. Turn on the Nursery Unit using the On/Off switch on the side. The green power light should come on. 6. Within a few seconds, the Parent Unit will lock on to the Nursery Unit and the top four (4) green LEDs will shut off. A second later, you will hear a series of beeps and the connection LED should change from red to green. Your monitor is now ready for use. 7. If the top four (4) LEDs do not shut off, power off the Parent Unit and the Nursery Unit and repeat steps 4 and 5 above. 8. If the connection LED on the Parent Unit does not change from red to green and the unit begins to beep, press the channel "ch" button on the Nursery Unit. Within a few seconds, the Parent Unit should lock in on the Nursery Unit and the connection LED should change from red to green. You may hear an audible beep during this process. 9. If the Parent Unit is still unable to lock in on the Nursery Unit (connection LED will be red and the unit will beep), power down both the Parent Unit and the Nursery Unit. Wait for 10 seconds then hold the volume down button on the Parent Unit while pressing the On/Off switch. When the unit powers up, you will hear a single beep and all of the soundlights will illuminate. Release the volume down switch and within 2 seconds you will hear two beeps and all of the Sound Light LEDs will stay lit and the bottom LED will be red. 10. Repeat steps 5

check your lamp door interlock switch.

no you most likely have a bad opticoupler in the power supply

First plug the charge adapter into an outlet, then plug into the unit. Push the power button to turn the unit on. Now, push the button for the light. The light should come on. At this point you hit the charge button and the green light should start blinking and there will no beeping. Then turn off the light. The green light should continue to blink and the unit will charge. This worked for me, hope it helps!

There are (4) 1000uf @35V capacitors all together on the DM board that need to be replaced some models have 1000uf @ 16V but they are all right beside each other and all rated at 1000ufs the voltages will be stamped on the capacitor along with the uf ratings.

Is the set completly dead...does the green light flash then go off. or when you plug it up does it come on for a moment?
