Topic:   OEM Equivalent Lamps / Bulbs

I just received and email from projectorlampcenter.com saying that they now carry OEM Equivalent Lamps/Bulbs. They claim that these have been tested and are equal or superior to the original. For example, they offer the the lamp for my projector, the Sanyo PLV-70 for $390.00 and the OEM Equivalent for only $274.00. A 30% discount or a savings of $116. I was wondering if anyone has tried out these new bulbs and can vouch for the quality. See http://www.projectorlampcenter.com/SearchResults.asp?Search=plv-70&Search.x=8&Search.y=12 Thanks, Rob

Topic:   lcd panel cleaning

re: cleaning LCDs First off, the two filters on the unit's right side (removable ones) need to be removed and vacuumed every 10 hours of use in a home environment, unless your projector box provides HEPA filtered air which fixes the dust problem there. Secondly, there is a 3rd filter on the left side -it should also be cleaned every 10 hours by placing a vacuum hose over it - it is not removable. Having done this, you will still get some specs of dust into the lcd panels - remove the top half of the projector case (the half with the buttons) - now use clean, dry air (I use a air compressor, dryer, tripple filter, and finally a point of use final ULPA filter to ensure there are no particles in the blow air. If you use the "canned air" be advised this is a LIQUID and if disturbed (i.e. angled to get into your projector) you may spray a refrigerant into your lcd permanently damaging it - this is why I prefer the air compressor & filter scheme. Now having the system open you can clearly see the 3 lcds (you can power it on in this state to see the dust that has accumulated, just DONT TOUCH the lamp electrical connections. Angle your compressed air into the gap between the lcd and the prism and you'll blow out most of the dust. You can vary the focus to focus on the dust particles instead of the lcd and see them clearly on your screen as you do the cleaning. When finished, give the whole unit a gentle blow-out to remove any hidden dust bunnies and then re-assemble the top half. This service should be done when you re-lamp or when you notice pink/green specs on the display. defocusing the image will show these pink/green specs sharply when the actual image is WAY out of focus. If you have successfully blown the dust out - you will see most of the specs are gone (don't try to get 100% of them gone - that's almost impossible - but 90+% is easy to do with about 3 bursts of 80 psi air onto each of the 3 lcds, plus 3 on the output of the prism to the lens. Now power off the projector, unplug it, and replace the top half - your image will look substantially better. Keep up your 10 hour vacuum maintenance and fewer particles will get into the lcds, and your fan will run quieter. This is highlighted in the service manual - I hope it helps!

I need to clean the dust blobs off of my lcd panel of my Sanyo plv-70. I am not interested in sending my unit 2000 miles to get it cleaned.

Topic:   Sanyo PLV-70 Help

I have owned the PLV 70 since Jan 2003 , and replaced the bulbs 4 times the first 2 years. then a problem of the blue blotch appeared at the center of my screen about 18 inches in diameter. I found out by cutting the power supply everytime I turned off the projector after it powered down so that it was not in standby mode and no power going to the projector...two things happened My light bulb lasted 2 and a half years and the blue blotch disappeared and never came back. It seems that the projector ran hotter with the light off in standby mode than when the light was on and the machine operating. go figure...........

Love this projector..BUT.. I have 2 recent problems. Please advise if you have any experience with this. 1) A blue splotch just showed up in the lower, left quarter, it is very distracting, especially on green images. The image is clear (in focus), but blue tinged. I just replaced the bulb and cleaned the glass around it, but it did not help. 2) Vertical lines also appeared recently. Very light, but regularly spaced about an inch apart. Changing contrast washes them out a bit, but the are still pretty visible on certian scenes. Thanks
