Try removing the new bulb and reinsert it and make sure it make a good connection. Be sure to follow your projector's instruction manual on how to change your bulb exactly.

Reset The Lamp Timer.

While simultaneously holding down (+ . >) and AUTO SYNC on the projector, Press ( I ) ON and ( - . < ) on the projector.

"LAMP 0000H" is displayed, indicating that the lamp timer is reset.

NOTE..... Make sure only to reset the lamp timer only when replacing the lamp. If you reset the lamp timer and continue to use the same lamp, this may cause the lamp tp become damaged or explode...

SOURCE: images has a blue color across the center

Wow, 3 in a row. As described on 2 other projector issues this is very similar to those others. I'll repeat the info here.

I assume this is an LCD. I don't remember the s4 being a DLP projector.

This sounds like the LCD panel used for the blue color has gone out. The image is made up of red, green and blue images layered upon the screen. If the blue panel has gone out then there is nothing filtering out the red light in the image.

It looks like yours has just a secone of the panel dying or comming loose from it's connector.

It could be a simple open and reconnect fix. I personally have never opened a projector, so I'm not going to walk you through it as I do not know how hard it would be to tinker with. It should eb a cheap fix for a true repair man though.

it's the light polarizer on the blue lcd panel. it's fried due to excessive dust and heat. unfortunately you'll have to replace the optical engine.

Black dots projected on my 3m scp716 projector


Actually, this is a known issue with this specific model as 3M has acknowledged. We bought 4 of these and 3 have had to be replaced in 3 years because of this exact issue. It requires the mainboard to be replaced and it is almost as expensive to do this as to buy a new unit. 3M has been know help to us on this even through we bought the entire setup (Projector, Arm, Smartboard) and spent over $15000.

Image is bright but there is a slight issue - on the left hand side a purple line displays vertically. Anybody knows why is this fault appeared and how could it be solved.


There is three LCD in the projector red, green and blue. If green LCD make any fault mean line or dot or dots then screen show these line or dot in purple color:
If line is very straight and sharp edges then green LCD is faulty and need to be replaced.
If line is not straight and faded edges then some thing in LCD block so your projector need service

My hitachi cpx 443 lcd projector recently has been projecting blue dots everywhere on the screen, how can I fix this or what is the problem?


How defined are the dots? Is each blue dot limited to the size of a pixel? I suggest you create a 3 slide image in powerpoint ..one slide completely blue, 1 red and one green. then project each image in turn and note what happens with the blue dot. My first thoughts are you have some pixels that are locked. Once that happens if are pretty much stuck with them. Optical it is impossible for a dust on the lens etc to cause them as if the picture is in focus at the screen the dust is way out of the depth of the field, sometimes you can focus the projector so that the point of focus is the lens surface but then the actual content will be way out of focus...none of which has anything to do with your blue dots.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

The projector lamp does not turn on


I have done this on several of our PT-LB50U's with sucess every time.Remove lamp cover and lamp.Then remove top of case by removing 6 screws on bottom.Remove metal shroud that would cover lamp 2 screws and remove 2 screws that hold lamp plug and move it away.You will see a little blue lever for saftey switch move it back and forth from top and bottom put back together and should turn on.

Does not display the color blue?


Hi,

lamp replacement will not solve your problem. The problem is with the main board or RGB Panels.

Yamaha LPX 510


I just saw your post & today is Mar 19,2008. I had the same problem and was pissed until I noticed YAMAHA has a good warranty, so I sent it back and they put in NEW OPTICS that are non-organic (I guess the original ones were organic) NOW my picture is much better than when it was new. This picture is so clear I can not believe it.
