I was wondering if anyone could give me an opinion on an issue with my Epson TW-8200w (same as 5030ub, as far as I can tell). If there is a more appropriate area of the forum to post this in, please let me know.
I bought the projector in Japan in September 2015. I have been largely pleased with it but a few issues have worried me a little: inability to make the centre of the image fully in focus, varying focus as projector warms up, and blue-ish patch in top-left quarter of screen when projecting light colours. From what I've read, the first two issues are somewhat normal (although I'd appreciate your opinion). Importantly, I assume these two are unlikely to get worse, since they're probably optical.
The top-left colour uniformity issue is slightly more concerning, as I wonder if it could get worse. It's not hugely noticeable while watching films unless there is a particularly uniform light-coloured scene. As there is only a year's warranty on the projector, I wanted to get some opinions about how normal/acceptable this issue is and whether it's likely to get worse.
I've attached a picture, in case it's useful. I should point out that I'm projecting onto a fairly glossy piece of paper at the moment (because I'm only in Japan temporarily), which is the cause of the yellowy patch to the right of centre. However, you will see the blue tint if you compare the top left corner to the top right.
