Sorry but there isn't one - that plastic button is (or it should be) in mesh with the plastic focus ring. To take it out you will have to dismantle the projector. If you're lucky this will be it, otherwise you will have to buy new parts directly from the dealer.

There is a "freeze" function available on the PR52 remote. Please make sure this is turned off / disabled.

Hello,

first of all , did you reset the lamp counter? did you clean the dust out of the projector? it may be overheating as well. if the lamp looks ok, you may have just blown the ballast.More likely a faulty ballast. Check connections.if otherwise and you are not able to check it yourself
contact skilled personnel to handle to check the ballast..
Hope this helpout....

I eventually fixed it; just a mechanical problem;I had to use strength to make the ring move again; 5586904.jpg
The arrow shows the direction of my movement; I had to use both hands; be very careful but also be aware that I had to put a lot of strength to manage to unlock it; good luck!

Hi.
This projector uses UHP metal halide lamp. This type of lamp cannot be tested. Often, when the lamp starts failing , its light will get dimmer before failing completely. Projectors usually display a lamp warning when lamp had passed a certain number of hours use.
Regarding the ignitor circuit, there is not part corresponding to this name. If you are talking about the board connected to the lamp, that is not an igniter, but an high voltage board. The board supplies high voltage of over 1Kwatts to the lamp. This board is tested simply reading voltage input and high voltage out. For safety reasons the test must be done by a training technician.
If you instead are referring to projector start switch as igniter, that is tested reading continuity with a multimeter set on Ohms, and checking if the switch is opening and closing circuit.
Regards.

the "try again after one minute" is a trial. if the new lamp doesn't work, the problem lies with the ballast.

Many projector bulbs will go yellow when they near the end of their life, is it an old bulb?

NEC VT47... | 425 views | 0 helpful votes


may be a input source problem -
lower the resolution of the laptop you are connectring to this with. 1024 x 768 is the max,

or possibly the bulb is at the end of its life

or the unit is overheating. check the vents to see if there is any dirt or dust. if so, you may need to try to clean out the inside.

Is the light blinking rapidly or solidly lit?

NEC VT47... | 169 views | 1 helpful votes


Try adjusting the resolution on you computer. I believe this is a native xga projector (1024 x 768)

If you go onto your menu and click on "setup". Press orientation and select the right one for your projector. It allows you to choose whether your projector is on a table top or ceiling mounted etc.

More likely your settings. It maybe interlaced mode, try changing the resolution/refresh rate. there is nothing else that will cause the shaking you described.
There is another shaking that can come from the heat given off from the projector, but this sounds like a settings problem.

From what you have described it sounds like a damaged internal lcd panel, can you post a photo anywhere and I can confirm?
