I have a new Optoma HD81-LV. It has worked beautifully and impressively for about 100 hours, then some thin, evenly spaced vertical white lines appeared on the right half of the projected image. The lines remain regardless of video source, resetting, and even when not connected to the image processor - implying that it is something going on inside the projector itself. I have sent several emails to OPTOMA for help, but haven't gotten a reply yet.

If the lines present in the menu when displayed this indicates device mounting troubles. Possibly loose in socket. If you change aspect of displayed image do the lines move, if they do, its an electronics problem, if they are constant, and nothing is displayed in the lines. Tighten device in socket, or seek professional service.
I had the same problem, reset the lamp hours by pressing 'menu, 619 , menu" and browsing until I found the setting, but then I also saw an option to test the lamp. The TV shut off when I tried this and 2 red lights indicating a new lamp is needed came on instead. It's probably the ballast and not the lamp, but I don't know that I want to put any more money into this set. I have only had it 2 years.
I read for hours, all of the questions and answers everyone had submitted and finally I found an answer where someone suggested checking the video connections. Sure enough the red cable connection was not pushed all the way in. I did some fine tuning and the picture is back to normal.....beautiful......I'm so happy....thanks to whoever wrote that suggestion......
Have you tried magic focus? if that doesn't work replace the pcb convergence board,, It costs $96
and takes 10 minutes to replace you will have to manually line up your
convergence afterward as the settings go to factory default. Everyone
that owns this set has or will have to replace this part within 3 years http://www.samsungparts.com/search/search.asp

Hello! Just a little additional info if you will on what might to expect. This is according to the repairman where my tv is still in the shop after almost 2 wks because of the need for parts: other than the lamp the only place to get other parts (ballast and color wheel) is from Optoma and if yu need the color wheel you will have to purchase the entire assembly ($999.99) because they do not sell it separately. If anyone knows differently please let me know for I am between a rock (not really) and a hard place.
