We have a HL-P5085W 'Capt. Kirk' pedestal DLP unit that has worked fine for several years. We have only used it with the 'high-end' inputs (DVI, VGA, Component).

We recently moved it to my parents' house. They wanted to use it with their cable feed, so we set that up.

The problem is that inputs through the tuner or the composite jacks look terrible. Everything is washed out like the brightness is too high. The color is weak. Adjustments seem to make little difference.

The menus look great, and we hooked a pc to the VGA port - it still looked fine.

I'm guessing the analog board is bad, although the component inputs look ok? Is there a connector that could be loose/missing that would cause the above symptoms?

Any special concerns in replacing that board or calibrations that would need to be done? The samsungparts.com site suggests that it is the BP41-00122D but shows it as no longer available, so it may be a moot point.

You know, it might be the cable itself. I don't see how it could look washed out. Maybe if you could post a photo of it. You're saying the input may be bad, but did you try all the inputs? What was the source video? Their cable box? There might be an adjustment you need to make to their cable as well, but the picture should never be "washed out." Your initial assessment may be correct though, and you could probably get a new analog board from Discount-Merchant.com, but I'd check out the cables first and jiggle them around. It's especially strange since you've never used them before...

Also, I have to warn you that you should probably not use the composite jack. The composite jack (that red, white and yellow) is usually crappy fir an awesome DLP TV and should only be used for 480i like older CRTs. The best picture will come from component (the r, g, g, red, white) or DVI (or HDMI).

The cable feed is fine, we tested it on a regular tv. We tried cable through ANT1/2, an over the air antenna through converter box to ANT1/2 and composite, and a Wii to composite AV1/AV2. All look like you turned bright way up and color way down.

Can I just replace the analog board, or would that throw off calibrations? Unfortunately I don't have the service manual to check what's involved...

bitmage,
The Analog board is most likely the issue there. It is a comonly failing part, right next to the Digital board, and DMD board. D-M.com is the only place where you can expect to get one at a reasonable place. PartStore and Samsung Parts want an arm and a leg for the board.

Let us know how it goes.

Alas, the analog board had no effect on the issue. The digital board is now on order as a last-ditch attempt to fix.
I'm getting to where I can tear down and reassemble the board cage blindfolded...

Ok, I've run out of ideas. You can see in the screenshot below what text on a white background looks like. Adjusting contrast/brightness makes the picture darker or lighter, but the 'bleeding over' white remains. The same source looks fine on another set.

The problem is only on the analog inputs (tuner, composite). Component, VGA, and DVI/HDMI all look great.

Tried so far:

Replace analog board.
Replace digital board.
Replace cables connecting analog--digital, and the DLP cable connecting digital to light engine.

Nothing has any effect.

I know the digital board was replaced once under warranty early in the set's life to correct a discrete remote code problem. I have read online that there is a 'Copy DMD data to Digital' procedure that needs to be performed when that is done, but have been unable to find it in any of the service menus.
