Very good advice on the spot. I took the projector down and opened it up to find that a black beetle had gotten into the light engine area. Took care of removing the bug parts out with soft air pressure . Everything else was very clean but used a camera lens brush to finish up. Put the unit back together very carefully and everything lit up as it should without the spot! Thanks for sharing your knowledge.

This is great! So many repairers just say "it's not worth fixing" and it seems such a waste to throw out electronics. I got a free 3LCD Epson that has an all-yellow picture. I took it apart and found the blue mirror has come loose. I was going to chuck it out but thanks to this vid I think it will be a fairly easy fix.

Fantastic thorough explanation. I just cleaned all the optics on my Panasonic PT-AX200U and I went a bit far lol. I removed the panels and had to realign each piece of glass with the alignment screws to get a good result. Each time I did an adjustment I had to remove the motherboard so not easy! There is a slight green color on the right edge of screen but hardly noticeable so I’m happy with it. New lamp replacement was needed after 2010 hrs, the bulb lasted me 14yrs which is amazing. Hopefully I didn’t go too far the picture looks like new. I did find what looked like a black smear on one of the glass panels so I cleaned it with a q-tip dipped in isopropyl alcohol. Thanks for this tutorial 👍

You can clean the optics inside, that’s fine, but you should never remove lcd panels from the yoke (prism assembly), you should never use chemicals or alcohol on polarisers and you should never use compressed air inside the projector optics.

@@MaxELECTRONICS good to know, I used an air compressor to blow out of the dust in the fans/power supply but not the optics, was very careful and gentle. I bought a lense cleaning kit from Best Buy and came with special brush, microfiber cloth and puffer to gently remove the dust in the optics. So far so good, my projector is working. When I was at Best Buy I saw a new laser projector. AMAZING! No maintenance on laser projector needed and no bulbs right?

Good day! Thank you very much for this very clearly and wonderfully presented information. I have the same projector you are showing here. I had a green output polarizer that was burned in the center (even though we only used the projector some 200 hours...ever!) I ordered a replacement polarizer from ebay and just replaced it, following a very helpful avsforum post with photos. I am certain I put the new polarizer in the same orientation that the old one was in. However, the end result is that everything is incredibly green now. As though there is no polarizer. Does this mean that I installed the polarizer backwards in some way? Again, I'm certain I placed it the same way that I the old one was positioned. Or does it mean I was given the wrong part altogether? Either way, I think I'm in trouble, because the JB Weld that I used to glue it in is solid as a rock and I kind of over did it! I am not optimistic that I can go back in, remove it, clean the area, and re-orient it IF that's what's needed. But I'd love to know what the utterly green image usually means so that I can decide if it's worth it. THANK YOU so much. - Matt

Hi, try adjusting INPUT polarisers, they should have a little screw on top and they can be turned left of right, power the projector on and make sure you have fully black picture on the input first and then adjust the polarisers until you get as black screen as possible, then try colour test pattern and readjust by colour, the rest of the adjustments can be done ether from service menu or user menu.

Hi Max thank you for the video’s, very helpful. I have an Epson EHTW9000W, it switches on,opens the shutter and fans start but, does not ignite the lamp. The lamp led then flashes red, The bulb has about 2000 hrs on it. I have the original lamp which still worked when I swapped it out, have put that back in and get the same result. Is it possible to piggy back with a multimeter the bulb wires (to check for power)when starting to confirm the bulb is the fault? Had some other faults like temp led flashing intermittently just before this occurred, and a green intermittent vertical line on the screen.
@MaxELECTRONICS2 жыл бұрын
It’s hard to say what’s gone wrong, have a look at a user manual and see what does led blinks mean. Also yes you can force start the bulb manually, PLAESE BE CAREFUL DOING THE FOLLOWING AS THERES HIGH VOLTAGES INVOLVED AND COULD BE LETHAL, IF YOU DO THIS YOU DOING THIS AT YOUR OWN RISK. You can expose the projector ballast ( the one bulb connected to, then you will find 2 or 3 optocouplers on the board near a signalling cable, (you’ll have 3 cables going to on, one line to lamp, one for power input and one signalling) once you located optocouplers simply short out the output (opto transistor side) of the optocoupler, and see if lamp ignites, if it doesn’t try with other optocouplers, if none will ignite the lamp then it’s ether lamp or ballast.

It depends, if it’s a slight green tint the it could be input polariser out of place, they don’t usually fail tho. It could be something misaligned or fell out of place. If everything is in place then chances are it’s your output polariser, maybe check connection of the lcd to the PCB.

@MaxELECTRONICS3 жыл бұрын
You’ll need to check by colour, try displaying just full green screen and come close to screen and see if it’s in focus evenly (you’ll be able to see individual pixels in form of the grid) then try red and blue. It could be LCD with dirt or most commonly bad polariser, it could be still doing its job at polarising but it could be warped and causing distortion, think of it as a car with really old tint on the window, then it’s still a tint but it’s old and you can’t see clearly out of it. That’s exactly what can happen to polarisers. But first try to determine if it’s only single colour that is out of focus, if they all are then it’s the prism alignment, it could of unglued from its position, then you just need to find there it was glued and re attach it

Easiest way is to try to see where the glue that polarises were held with is matching up with frame. Other tip - red polariser is slightly different tone then green and blue. And the green and blue just try placing them in roughly and turn the projector on and see if they are match or not.
