I've followed this thread from the beginning so I'm just going by memory, and I regret I can't give you hard and fast data or even point you to the posts.

It looks like you're leaning towards an upgrade, and all you need is a little nudge. Well, despite the fact that I love my set and its beautiful image quality, I have to recommend you don't dump any money into it, and take the plunge on that new one you've got your eye on.

I agree that if it were only a lamp, the decision would be easy. Sadly, I don't think that's the case. Good luck.

I've had this wonderful TV since 2006 and in last few weeks have connected it to a newly built HTPC. Well, I've got some serious overscan happening. I can BARELY see the right edge of the leftmost icons on my desktop - can't see the W7 taskbar at the bottom at all and the right side is just as bad along with the top - I'd say it's 5-6% overscanned at least - a real PITA for an HTPC.

I want to try n correct this at the set level vs. drivers and ruining the 1:1 pixel mapping.

So, I have gotten into the service menu and all I'm looking to do is shrink the sides/bottom & top a bit, but don't know where those setiings are at. I know the risks and will make very small adjustments at a time, if it's even possible.

I have tried all of the setting in the UI to no help as some of the newer LED DLP settings like "Just Scan" and "Extend" don't exist on my TV. Is there newer firmware available that would offer these setting or improve anything for me? Is it even possible to flash firmware on these things?

Can someone point me in the right direction in the service menu please? Thank you! And I'd buy you a beer or twelve if I could!

The light engine was replaced, and that didn't get rid of them. What else could it be? I don't think it'd be the screen, if the position of the spots are different since the repair.

EDIT: I do have the TV near a wall. Some light does exit out the back of the casing, perhaps it is reflecting back off the (white) wall? I'll have to try putting something darker behind the set and see what effect that has.

I have a HLS6187W that's I think 5 years old now. It's still on the original bulb! which I can't believe, cause this TV is used quite a bit. Last time i was in the SM (about 7 months ago) I think there was something like 12-13,000 hours on the bulb.

I've noticed recently at random times that there is slight and I mean very slight flickering on the screen, which when it happens there are very faint lines that appear horizontally across the screen. They go from the top to the bottom at random intervals. And once it starts it only really happens on very light or white images (that or I can only see it happening on those color levels)

When it first started i figured it was my Slingbox going out, so I hooked my Tivo Premiere up to the TV straight component (TV doesn't like the HDCP on HDMI for remote viewing) I thought that was the problem until 2 weeks ago when it happened again. Now it seems to happen every couple days when the TV is on for a good 3-4 hours.

So tonight it started happening again, so I figured I would test it out on the VGA input with a solid white screen to see if it indeed is the TV and not possibly my Tivo Premiere. Tested the VGA input and no problems, then switched back and no problems since.

So I still don't know if it's my TV or Tivo at this point, though with the age of the bulb, I'm really leaning towards it being the bulb on it's last leg. I've read reports of people talking about dim images before the bulb going out, but currently my settings are Custom mode, 78 contrast, brightness 52, on color mode cool 1, and it's definitely a little darker than when i first bought it but its not really all that dim. Also I've noticed if I'm watching something in 4:3 (not often but it happens) that the sides of the screen are starting to band in a little bit. Not a huge deal cause I can't notice it at all when I'm watching anything widescreen but figured I'd include that as well.

so do you all think it's the bulb?...if so, I've heard they aren't that difficult to replace. Is that something I can do myself or play it safe and have a tech do it? Thanks for the help.
