Question about LG RD-JT40 Multimedia Projector

2 Answers

RD-JT40 powers on but nothing shows

My projector suddenly went dead while i was using it with no warning of the bulb needing replacing or that it was too hot. The projector now makes a clicking noise for a few seconds when it is turned on and after a few more seconds the projector turns off with the bulb wanrning light permanently on. I assume I need a new bulb but I am concerned that even with a new bulb the same problem will occurr. any ideas??

On the plate you have removed to remove the lamp there is a pin. So refit the plate("doar") and the noise will be gone. There should not be any damage to the projector (I did the same this moring with no bad effect to the projector)

does it look clean inside
is it fully home on the connecting pins
are the lamp door and fan switches made correctly

Lamp reset LG RD-JT40


Try to do this, press the ENTER button on the TV and the MUTE button on the remote at the same time. After 5 seconds the screen should come up and it will read "Lamp use time...Total lamp use time ....lamp reset" Press the center button on your remote (the circle button right in the middle of the four directional buttons) and you will be reset to -0- again. Your orange light should now be off.
Good Luck.

NEC vt470 projector suddenly not turning on


I'm with Greg on this, I've had both of those problems individually on different VT4xx's (having both a number of them and a working knowledge of screwdrivers, figured out what was up by process of elimination). Sometimes bulbs die early - if it's really early you might want to see if there was any warranty period remaining on it - and the power boards in these projectors do sometimes break down. They were built in an at-risk period for having troublesome power capacitors installed into them, for starters...

If you are e.g. at a school which has several of these projectors issued to individual teachers, organise to swap the bulbs over between both your units and see which, if either of them, still work afterwards. If theirs was originally working, and after the swap, both are dead, you've got a dead bulb AND something else wrong with the projector, POSSIBLY but not necessarily that PCB. If yours then works but theirs doesn't, it's the bulb. And if there's no change, then both bulbs are good but your projector is toast.

And if it turns out that it's a projector fault, unless either you or an in-house tech can investigate and do the fix either for free or very cheaply, it's probably not worth getting it repaired. These models are really quite old and under-spec these days, and you can replace the entire thing with a brand new model of similar specification - with a working bulb installed! - than it would cost you to buy a single replacement bulb for the NEC.

How do I change the lamp? Lamp came with no directions. This is a HD72.


Hello there,If your movie projector light bulb has stopped working, there are some simple steps to take to get your movies playing again. The hardest part may be finding the correct replacement bulb. There are so many different models with their own specific bulb. Here are some steps to follow to replace your burned out light bulb.
  • Locate the bulb in the movie projector. You may need to use a screwdriver to open the bulb compartment. Check your owner's manual for proper procedures.
  • Step 2.Remove the movie projector light bulb or lamp. The bulb must be cool before you take it out. Use a tissue or cloth to remove the bulb because the glass bulb is very fragile. Do not throw away your bulb yet, you may need it to help find a replacement.
  • Step 3.Find replacement bulb. The Better Lamps website offers a wide variety of light bulb models. From their homepage select the brand of movie projector you have and using the model number from your old bulb, buy a replacement.
  • Step 4Replace the movie projector lamp or light bulb. Do not touch the bulb with your skin. This can transfer oils from you onto the bulb resulting in a hot spot which can make the bulb burst. Use a tissue or cloth to handle the new bulb to screw it back into place and then replace the cover.

    No power


    there are six screws in the base and two in the back of the unit. After taking off the top I saw a red button on the front that was a little pushed out - I pushed it in and I got the led lights back :)
