Anyone else that purchased a sim in a box that came with the Eiki ek-308u Projector have an issue with the brightness dimming randomly and than returning to full bright. Some days doesn't do it and others it may do it every few seconds to minutes. Almost like its randomly switching ECO mode on and then off. I only play at full brightness and it is very bright. Has only about 500 hours on it. Doesn't seem like a bulb either as that isn't a normal sign of where at least with my movie room projector I have. Called and left Eiki a message and haven't heard back yet.
