Hello all, I was wondering wether anyone has had a problem with smudges that seem to be behind the screen. I noticed this a few days ago and i just thought my 7 year old touched the screen and left a couple of finger marks on it,but when i finally decided to clean the screen i realised the 'marks' were behind. This has now become really frustrating as all i do now is stare at the 2 smudges. They are not really big smudges and but can be seen vividly especially on bright/lighter pictures. I did a search and apparently there is a secondry screen behind the outer one and the smudges are caused by the lamp on the inner screen? Is this true. Also it doe'snt matter if its warmed up as they are there from when it is switched on. So,what are my options?,is it the inner screen and i need to contact Optoma for an engineer?,or could it possibly be the lamp that needs a clean? Also has anyone else had this problem with any other DLP? Hope someone can help, Thanks ps.I've had my RD50 for 11 months. I have now found out this could also be static,if so would anti static spray work?
