Question about Sony VPL PX40 Multimedia Projector

1 Answer

Two problems, first the menu appears to be burned into the projection, the bulb has less than 100 hours. Second when black is supposed to be projected it projects blue?

The menu appears to be "burned" into the projected image.

Why would the color black be replaced with the color blue, is some setting off or what would cause this?

You have a bad lcd, you would probabaly have some blue lite leakage also. Any lcd projector should not be left on the same image for long periods, it wears out the pixels that control the lite thru. The blue lcd is usually the culprit.

My MP610 powers up, but only projects a weak light, not the usual start-up screen and menu. It has not been used for about 4 months. The bulb only has about 200 hours or less of use. Thanks.


Can you get a menu to come up even though it may be very faint.
Does the lamp appear very bright through the side of the unit like it used to in the past.
Take the lamp out and check if it looks Ok, and also if the glass plate that the light first goes through is clear.
Check if there is anything in the lens unit that might be a problem like dust or moisture.
Apart from that if the unit hasn't been dropped and a mirror inside hasn't shifted then you may have to check the optics system.

I,ve got a red spot in the screen i replaced the bulp but stil have the problem


it is most likely a burned polarizing filter. There is a polarizing filter on the blue light channel and another on the red channel. When black, or other dark colours are displayed, the red polarizing filter is supposed to block ALL of the red light being projecter. If the filter is burned, some light slips through and creates a red tinge on the projected image. If the red tinge only appears on dark images, but is absent when the images is completely white, a damaged filter is likely the problem.

Seems its hard to buy them. Best bet is probably buying a broken projector from ebay and stealing the filters out of it.

Bluish image appearing on screens


It sounds like the projection lamp is beginning to show its age. How many hours of use does the unit have on the bulb? The bulb are typically rated for about 800-1600 hours of use before they go bad. The bluish image on the screen image is a typical tell-tale sign that the bulb is going to need replacing.

Most of your better projection units will have an internal time counter of the bulb life from the time the unit is first used or when a bulb is replaced. Check to see if your unit has this feature, if so it will show you on the screen display what is the total number of hours on the bulb and the estimated remaining hours of life.

Be aware that the replacement bulbs are NOT cheap and usually will cost you several hundred dollars, I have seen bulbs for professional projection units used for large convention/presentations have bulbs costing as much as $500.00 USD.

One other last thing to check is to clean the lens of the unit both inside and outside. To clean the inside, you will need to remove the bulb (be sure to wear a rubber glove as the oils from your skin will cause the lamp to blow, (causes a hot spot)). Then using a cleaning wipe, just as one used for cleaning microscopes or glasses, wipe the lenses. The discoloration might also being caused by dirt and oils on the lenses.

I hope this shed some light on your church's projection problem.

BenQ PB6100 extremely dim screen/projection


Hi skeeterJ

This is most probably your lamp , I have had loads of PB6100 's that has even had less hours on the lamp than yours and needed replacement.

Keep in mind that the 2000-3000 hours they talk about on a lamp is just a rough factory estimate. The time you get on a lamp is determined by how you use the Projector - because at the end of the day the lamp is just like a globe in your home - it doesn't like being swithed on and off for short periods. This is a mistake most Projector owners make - by thinking they are saving the bulb's lifetime and switching it off for short periods.

You can take my word on this as I am a Authorised BenQ Service Technician.

I've had clients who got 10 000 hours on one bulb just because they left the unit running for longer periods.

Lamp Part No : 60.J8618.CG1

Easiest way to make 100% sure before investing in a new lamp is to take out the lamp by opening the lamp door at the bottom.
Check for any vein like looking marks in either white or black or a bubble on the shaft.

If you have any further troubles or questions , feel free to post another posting and I'll answer it for you ASAP.

Thanks for using Fixya and good luck !

On the bottom right side of the screen it is sayin life expactancy 17 hours


Had the same problem and drove us nuts. What happens when you put in a new bulb is it starts a expected bulb lifetime hour count down. This does not mean the bulb will burn out but it might be time to have a backup. What you can do is go to the menu and search around to reset the bulb counter as if you put in a new bulb. We did this one year ahgo and project is still working fine. It is, however, mounted to the ceiling so there are no vibradtions during cool down.
Good Luck
