Question about Panasonic PT-LB10VU Multimedia Projector

Panasonic PT-LC56E projector

We have started to experience red ghosting mostly around the bottom right hand side of the whiteboard / screen. Is this a limp problem? One of the projectors is only showing 76 hours runtime on it current bulb. Or is the fault to do with the internal coloured filters.

We have had to replace the said filters in the past on a Philips projector, due to a grey central circle on the whiteboard / screen.

Do you have any idea what can be done it rectify this problem.

Regards Ian

Re: Panasonic PT-LC56E projector

That projector has not been made for some time (7-9 years I believe) so there are probably several thousand hours on the projector, and at about 2500 to 3000 hours your panels start to fail,, sounds like the LCD panels are warping, and you are loosing convergence.

that projector would cost about $500.00 to replace with a newer brighter unit, with a new warranty.

but the "E" means this unit is for europe only, so your prices may vary

Why red light is on ?

Its the most common poblem with the ax 100-200 projector.Many a times only the ballast requires to be replaced.yet on may occasions both mainboard and ballast requires replacement. its best to confirm with a good known working ax200 and replace first the lamp, ballast and the ax 200 lamps also have failed premature as per my experience.

I need to reset my lamp counter on my projector pt-lc56e but i dont know how please help me

After changing the lamp you should be able to turn on the projector and it should run for approx. 10 minutes, allowing enough time to reset the lamp counter. Hit "Menu", select "Option 2", hit enter, which will bring up "Lamp Runtime", press and hold enter button approx. 3 seconds. The selection will change to "Time Reset (Power Off)". Turn off the power and it will reset.

I have a panasonic pt l500u, just started getting large yellow spot in middle of screen- looks like a giant finger print. Bulb was replaced less than two months ago.


The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE. The blue seems to be failing in your unit, for instance if you mix red and green you get yellow. Have a local shop service the unit and clean and refocus the unit back to factory spec's..

PT-L735 U projectors. Green screen and stretched

The green is the result of the blue device failing. Happens about 4000 hours or so. LCDs can't handle the heat. Check the scaling of the image of the second projector. 16x9 vs 4x3.

good luck

I have a Panasonic LCD projector ( PT-AE700U) - I have had it for 4 years. Recently, I noticed it was projecting "blue" pixels on the bottom right hand side (small size maybe 3 x 8 inches) . Over the past...

your color calibration may be off. see if you can set the red green and blue settings all to "0" and see if that works. may want to refer to your manual and see how you can do that and also see if there is a auto calibration

ok this problem occurs mostly due to the loose connection in the VGA cable between the pc and the projector..
try changing the cable to give any other input and see it and then confirm it... that the color sensor of the projector is weak...

HItach cp-s860 problem

I have the same Hitachi CP-S860 and have found the problem is with the convergence on the left and right sides of the picture. The one I am working on has a bad ghosting problem also - you can really see the ghosting when the MENU is on the screen. The center convergence is OK. Following Pics show Circle / Cross pattern - 1st pic the red, green and blue are turned on - 2nd pic shows green and blue on only. I do not have the service manual for this set so I do not know the convergence procedure on this one. I have mostly been repairing NEC, Sanyo, Panasonic and Christie LCD & DLP Projectors.
