Attention Sharp ZW99 owners:

I recently (April/01) purchased a used ZW99 LCD projector (700 lamp hrs) for watching DVDs and football games. Fairly new to the home theater/projector arena, I was impressed with the size and sharpness of this type of system for just over $2K.


However, after a few days of use, friends and I noticed vertical lines streaking down the picture -- especially clear when there's a white background. Afterwards, we could not avoid looking at the lines with any input (DVD, satellite, cable, laserdisc, etc.). A major problem for such an expensive (relatively) product.


Took the projector to an authorized Sharp repair dealer. Have not seen the projector for 75+ days! They could not correct the problem, so they sent it to the Sharp repair facility. Sharp claimed to have fixed it and sent it back. The repair shop still noticed the vertical lines and returned to Sharp a second time. A head technician at Sharp said that this is the way those ZW99 were made and sent the projector back again -- not fixed.

Two and half months to tell me this product is defective?! http://www.avsforum.com/ubb/confused.gif


My question is:

Anyone else with a ZW99 experiencing vertical line problems?


Thanks for replying! http://www.avsforum.com/ubb/smile.gif

P.S. Picture is large to show detail. The lines appear strong on the right side of the picture.

Hi, I do not have a sharp but have seen this before.

This is common with a lot of LCD projectors. Most projectors I have seen show a little bit of this but not noticeably in most program material. Do a search in this form on vertical streaks and you will find it has come up before. I have not yet read about any fix to the problem.

Your picture does show it quite well.

Thanks for the replies so far! http://www.avsforum.com/ubb/smile.gif

Looks like some may have the same experiences...


I'm finding it rather difficult to believe that defects like "vertical streaks" are allowed and accepted on this type of expensive video equipment. Sure, if I bought a $300-$400 large TV from Circuit City or Best Buy, I'd accept a minor flaw since I didn't pay that much.


But c'mon...over $2K dollars for something that has a very major flaw (vertical lines) along with dead pixels (which I knew about before the purchase)?? The main reason in forking over this type of cash on a projector is "for outstanding, large screen video" right? Why buy the HDTV converter box or progressive DVD player when the video output is flawed?


It's difficult and frustrating to have this LCD unit in the shop for 90 days and have everyone, including Sharp technicians, tell me "that's just the way the projector is...no fix" http://www.avsforum.com/ubb/mad.gif

Last week I was adjusting the convergence on this same model and I didn't that steak at all. Can you make the projector to display only one color to see if the streaks are present on all colors (red, green and blue)? If there is present on all the colors that looks to be a video noise, probably cause for noise in the power supply. I think that you should change the projector or at least see for yourself that this problem is present in another unit.

I don't have this same model right now, but I have one 55 and one 96 at home now and I cannot see that problem on any of then.

I had this projector for the better part of 2 years and am a freak when it comes to lines in the image that don't go with the flow and those would have bothered the heck out of me if mine had had the same problem, but mine was problem free.
