I guess I consider myself quite lucky with my JVC D-ila TV. I've had it for over 5 years and I am just now getting around to replacing the bulb. It's not blown but I figured I would go ahead and get a new one. Been getting the message to replace for a few months. It's been a real good TV.
However, now since I have replaced the bulb with a new Philips replacement I can see that the screen looks different. On the right side there is a slight blue/purple color. From the very center and moving to the left side of the screen it looks more normal looking. It shows up obvious when my Blu-ray is showing it's screen saver (black background with floating pioneer logo).
So I have read a lot of things on the forum about issues and it sort of sounds like it could be the light engine giving out.
The weird thing to me is that if I put my old bulb back in then this issue goes away and the color is uniform, no blue/purple color.
So would my old bulb which is getting dull just be covering up a light engine issue since it's not as bright as the new bulb? Maybe a defective bulb?
I wish it was but I can't find anything wrong with it. Actually I got another bulb and it does the same thing. This one was directly from JVC. It's not quite as bad though. I cleaned my light engine out real good, took the screen off and cleaned the mirror and the inside of the screen and still no luck. So it must be something I'm going to be stuck with.
It's not unwatchable but can be annoying at times.
