I'm not sure what board you need but be aware that discounttvparts.com sells USED boards.
If that's what you're looking for great, but I thought I was buying new and they only refund you 70% minus shipping when you "make a mistake".
Good luck!

Awe-some! :mrgreen:
Glad to help. 8-)

Took out the light tunnel... couldn't see anything out of alignment. Tried shifting the mirrors I could see - didn't seem to do anything (for better or worse). When I'm brave enough I may try fully disassembling the tunnel, but 1st I'm going to focus on the other issues. I did some research on Wikip...

There should be a safety switch activated by the back panel/lamp cover - if the switch isn't activated the TV will remain off. My model has a stack of small plates attached to the back panel that extend to push the switch. Sometimes they can come loose, not making contact. To be sure the switch is n...

FixItMeself

Look like you're right!
See section 8, 8.2 "Power LED Flashing timing table" in your service manual... according to that the fans should be the issue.
Wish my service manual was this easy to read!
Let me know how it goes.

FixItMeself

I found your service manual online... here's the link:

FixItMeself

Yeah, unfortunately that ended in April for my model and on October 22 for others.

FixItMeself

Yeah, not only color but black-white gradients too.
The index delay seems only to effect actual color gradients (red, green, blue) - can anyone confirm/disclaim this?

FixItMeself

Sure thing - let me know how it goes.

For most models you can reset the TV by turning it off and while it's off holding down the power button for several seconds (try 30 to be on the safe side). Some models require you to reset the lamp... for more on that see this link: http://www.fixya.com/support/t363695-projection_lamp_timer_reset I...

Have you tried resetting the TV? Sometimes that works.

I was FINALLY able to figure out how to upload the video I took (had to figure out the whole HD thing - lesser quality vids are too pixelated to see the distortion). You can see it here: http://youtu.be/NgDjoso_Lxk?hd=1 The s-video bit is still somewhat pixelated - you can sort of see the quality is...

FixItMeself

No worries... you can always delete the other one. Someone else had a similiar issue - here's one reply that clarified it very well: by ovadoggvo » Fri Mar 27, 2009 4:38 pm There are many reasons that could cause the lamp to go out sooner than later. Instability is the most common. Constant on/off w...

Well, I went into the service menu. My factory index delay was set to 61. The color scales at the bottom look perfect, color wise, white is white, and RGB look great...except for the left side of the screen. The dark whites (grey) fade to very dark red. The dark reds are a jumbled mess of very dark...

FixItMeself

If your model is like mine there's a small "lamp cover switch" that has to be pushed by the back panel in order for the lamp to come on. Sometimes the backing can get warped, so try taping the switch pushed all the way forward or back. If that doesn't work it may be a power issue or a bad ...

FixItMeself

Grand. This sounds like my issue. Well, I'll give the alignment a try.
Unfortunately my TV's alignment coverage ended in April but at least I know what to fix now.
Thanks! :)

FixItMeself

A blown lamp may mean a faulty bulb or bad ballast. If your bulb was under warruntee I'd advise requesting a replacement. Try replacing the lamp with a genuine bulb (manufacturer original - no cheap "compatible" alternatives)... if it blows again then it's the ballast. If you don't want to...

I am trying not to thread-jack anyone, but the moderator won't approve my thread, so I'm not getting any help. Is there something I have to do to get it approved? That happened to me when I first tried to post a new thread... after I posted a couple of times on other threads I didn't have a problem...

FixItMeself

The problem you having is probably just the index delay which you need to adjust from the service menu, if the model begins with an HLP then when you replace the color wheel , the new color wheel should come with a sticker that will have the RGB values plus index delay fail to do this may cause the...

DANG!
Nix on all that!
The distortion is back and so is the contrast issue.
I'm thinking this has got to be the DMD.
I turned the brightness way up and took a video that should show you waht's going on... will post it soon as I can.

Suggestions welcome.

Somone else had a similiar issue and the answer by "techmaster" was as follows: "Ok.... what you have here is a light tunnel issue. When you take out the light tunnel there will be a piece of "ALMOST CLEAR" plastic on the small lens which has shifted into the viewing area wh...

Company unmovable... returning part - had to pay return shipping and a 30% restocking fee. :roll: Got a new part from someone else... should be here within the week. So, lesson learned from all this: Avoid sites like DiscountTVParts.com! You pay for what you get... if it's too good to be true then I...

Well, I've got the board already packaged back up but I can tell you that it has the same "oily" look mine does (pictured earlier) - just not quite as bad. They said that the board has been tested by their Quality Control dept. but my concern is that if it's already showing signs of overhe...

FixItMeself

The whole board assembly is BP94-02065A - just the circuit board is BP41-00120C.
I can't find the circuit board new on it's own so if you know where I can find one great.
I found the BP94-02065A for around $140.00 new.
Thanks!

FixItMeself

The site it Discounttvparts.com.
Sneaky site... only place indicating that they sell "recycled parts" is their About Us page.
I'm currently trying to work it out wth them.
Will let you know how it goes.

FixItMeself

Well, nix on that. The part I received is showing signs from overheating too - didn't know the company I was purchasing from sold used parts. :roll: Sorry folks... gonna have to wait a while longer. Hopefully I'll get it sorted with the company and this thing fixed before the end of the year! :mrgre...

Got the part today and hope to install this week.

Was finally able to order the board... hopefully will arrive within the week.
Will update you once I get a chance to install.

Alright, got around to disassembling the DMD board and it is a bit "oily" but otherwise seems fine. Cleaned it up and reassembled. Did something really dumb and unscrewed the projecter lens to clean it - when I reassembled the TV the picture was all out of focus. :roll: Spent the next 30 m...

Yeah, when you don't hear back from someone for a while on forums like this you think "Gee, hope they remembered to unplug the TV first!" :? ... *DZZZZZZ*! :shock: Had a crazy couple of weeks but am hoping to get to it before the weeks end. Will report on that soon as I can. Thanks for the...

Have you made any more progress?

Okay, I finally got around to taking out the analog and digital boards. The analog looks fine and both are fully intact but it looked like burnt sugar on several parts of the digital. burnt 1.JPG I cleaned both boards up good and HDMI actually looks a bit clearer, but the s-video is the same.

FixItMeself

Okay thanks!
I'll keep you posted.

FixItMeself

HDMI is a bit grainy and fuzzy (like a picture when the camera is a bit out of focus) and the contrast is very slightly faded - the digitizing (unsmooth color) is also only slight. S-video is 2-3 times worse - looks like an old, faded, fuzzy print with digitizing. The light amping-up/amping-down pro...

FixItMeself

Yeah, heck of a lot better - I used to have a hard time telling the difference in quality between HDMI and S-video. HDMI is a bit fuzzier than it used to be too (grainy and a bit blurry - like it's slightly out of focus) and the contrast for both just isn't what it used to be. S-video is far worse, ...

Reseated the lamp - no effect, shadow's still there.

Nope, not the DVD player - same problem with my other one (shadow, distortion, pixilation).

I have been messing around quite a bit inside the TV, but I doubt that's cause - the shadow showed up after I began adjusting things on the service menu. I'll reseat the lamp to be sure.

Distortion only for s-video... HDMI seems fine.
I don't minding spending what I have to I just want to be sure I'm getting the right part.
Gonna try the new player shortly.
Thanks!

FixItMeself

No, it does not effect the TV menus.
I am going to try a different DVD player to make sure that's not the problem - doubt it though 'cause all this started with changing the color wheel.
Will report back later.

Any ideas about the pixelating/banding effect? DMD too?

FixItMeself

Sorry for the delay in response. Okay, input's fine and I've been messing with more service settings which seems to have sorted the color issue for good and might have fixed the contrast problem (still need to test that out a bit), but I've still got the grainy/fuzzy issue. I've also got a banding e...

Try checking all your circuit boards, see if you can find any visible signs of damage (anything that looks burnt, cracked, melted etc...). See also if you can locate a fuse (very small, clear, glass tube with a tiny wire running through it) and see if it looks blown (smoky glass and/or the wire will...

FixItMeself

Input, right - sorry, missed that bit... I'm a bit dense right now - by input you mean does the TV respond to all the buttons on the remote?
If yes, I believe so... I'll check that out too and report back.
Thanks!

FixItMeself

Thanks - I'll check that out... any way to visually tell if the DMD board is defective? After my first post I realized that the grainy/fuzzy with faint horizontal and vertical lines effect is isolated to s-video. It almost looks like some sort of intereference...? P.S.
