I purchased a Sharp Z10000 two months ago and, until recently, I was extremely pleased with it. It really is an excellent projector. A week ago, I started to notice a slight flicker (I had about 60 hours on the lamp). Having seen reference to this problem previously (after purchase I might add), I read all the posts and background to this problem and concluded that I needed to obtain a replacement lamp under the 90 day warranty. I spoke to my retailer and explained all of the background with the result that they contacted Sharp UK and advised that they [Sharp] have agreed to replace the lamp under the warranty. I just need to fill in the warranty form and send it off. Upon examining the form I find that I must send off my existing lamp with original proof of purchase. The form contains no contact details other than postal address or any explanation of the procedure. I was not given any reference number or contact name. The warranty states that it only covers failure caused by defects in design materials and workmanship on lamps fitted during the process of manufacture of the projector. It also states that the warranty does not cover failure caused by accidental damage and No responsibility will be accepted for claims lost, damaged, or delayed in the post. Im naturally concerned therefore about dispatching such a fragile and valuable component as the lamp without more information about how this will be handled. Ive spent over 2 hours this afternoon trying to contact someone at Sharp who can give me some information. The closest I got was to speak to someone in Tech Support who said that they didn't know how that department [Lamp Warranty Claims] operated, couldn't give me a direct number as it didn't have one and when, exasperated, I asked how I was supposed to discuss the procedure with any Sharp employee, I was told 'tell me what you want to know and I'll email them'. The conversation went downhill from there. Can anyone offer any wise words or advice as to how I should best progress this?
