Question about Sony VPL-CS7 VPL-CS7 MMPROJ XGA 1800LUMEN 6LBS Multimedia Projector
My Sony VPL-CS7 has only had 600 hours bulb use.. I thought it was dead and not showing anything until i switched it on one day in a very dark room and discovered that it still was working but i just cant see anything in a dark room except if the room is extremely dark hence rendering it useless during the day as it will still be light.. Can anybody help me on how to get rid of this problem. Thank You.
If you need it you can get the user manual on this link; http://esupport.sony.com/perl/model-documents.pl?mdl=VPLCS7 check page 29 - brightness setting adjustment just to be sure this is not the problem. check page 36 - lamp mode - try high if not already set on it. Check page 42 - cleaning the filter - this can stop the projector functioning properly, but i don't think it's the problem in this case If the image is being projected exactly as normal, apart from the brightness, then the problem is most likely a failing bulb, despite the low hour count. Just possibly (but unlikely)there is a power supply problem that is not feeding enough voltage to the lamp, only way to tell for sure would be to either get a meter on the lamp terminals, which looks practically impossible with the lamp in place, (possibly will give a reading without the lamp, but the terminals may be disconnected from the power when the lamp is removed), or replace the lamp. Are there any flashing lights or error messages at all, does the projector seem hotter than usual, is the fan running as normal? could you actually see any error messages on the projected image if they were there? try really hard to read them if you think there could be something there. Try a different input source, unlikely problem but possible. Especially in smoky environments the lens can get quite a thick layer of grime on the outside - easily cleaned off gently with some vinegar and soft paper towel/soft cloth. This made enough difference on a similar one in a bar near me to give them 3 months more with the same bulb. Worth a try. If you need to source a bulb you need Sony LMP-E180 there appear to be no cheaper substitutes, you can get one direct from sony uk on this link; http://www.sony.co.uk/view/ShowArticle.action?articlesection=1&article=1158155174490&site=odw_en_GB These lamps are often cheaper from the US even with postage, if you can find a dealer who will send you one, check this link for some ideas; http://www1.epinions.com/t-sony-lmpe180 I got a lamp for a similar sony projector sent to spain a few months ago, saving about $280!!! - I'll keep trying to find the details of the company I used, no luck at the minute. Hope this helps, post back if you have any more info :)
