56H80 Review/Calibration

<< Back to Miscellaneous Page

Tip from by Mr Bob:  "Well, I've now seen one of the new ones which don't allow us into the Designer menu anymore.  At least not the way they used to, and I don't know any other way to get in.  Therefore, no user center calibrations for Color and Tint - on either NTSC or HD - and definitely no STCs or QA02 resets.

On the positive side, it uses a new, non-glossy surface on the fresnel lens inside. All fresnels I have seen before this one have had a glossy surface which I have always suspected of possibly reflecting light back into the optical cavity. This one has a flat, non-glossy surface. Slanted light patterns will definitely not be reflected back in full, as before.

Unfortunately, it was daytime during the glare screen removal op, and even tho I tried it with and without the glare screen moved to the back of the stack, I couldn't see any difference in the reflection of the Pluge pattern from VE, with and without a surface that was glossy. Perhaps someone out there will test out this new design during nighttime viewing, and report in what they find. Stacy Driver, you out there?

Another strange thing about this unit is that when the color level is turned completely off, for greyscale purposes, the dark areas turn a bright green. And I'm not talking a subtle shade of green - I'm talking a bright garish green, which increases the more you turn the color down, until with color at absolute minimum, the darks are positively glowing with kryptonite green.

As such, I doublechecked the greyscale at the normal color level, and it's just fine! Never seen this one before. I've seen the greyscale change in response to the Brightness being turned up or down, but never the color level. So I left the greyscale calibrated to D6500K at the given, blue filter test calibrated color level, and left it at that. We always calibrate whatever needs calibrating at the ideal levels everywhere - which often requires lots of back and forth, due to massive interaction activity among the levels involved - so I left the greyscale as it was, plus the other levels. At ideal levels, everything looked exactly as it should, so I was satisfied. I just like to turn the color level down when doing greyscales - it gets rid of the rainbowing often present in the dark areas, making them clean and unbusy - and was not allowed to do so on this occasion.  Otherwise, the picture turned out as all the Toshibas I've done always have - delectable.

One point. 

If you're going to remove the very rigid and therefore structurally supportive glare screen in toto - like I ultimately did, just on the off chance that the dull surface of the fresnel lens that faces the mirror DOES minimize internal optical cavity reflections - there will be lots of slop in the fitting of how the frame holds the now relatively flimsy screen pack, exacerbated by the fact that the lens pack does not arrive having been taped together at all. AND taping just the fresnel and lenticular together, with the rigid glare screen no longer present in that stack, will not help with the pack's new spinelessness and lack of rigidity anyway, once the glare screen is removed in toto.

The worst bend will occur 1/3 of the way from the bottom, where the screen pack settles in, leaning back towards the mirror the most. I suggest you shim it at that point from the back, to support that particular bend.  Doing so will keep everything flat, if not totally pasted up against the frame itself. I folded up half of a discarded envelope for each side. If you fold it up enough, none of it will show up in your picture.

Also, the frame no longer falls apart when you take out all the screws necessary to remove the screen pack. Now you don't have to undo the corners at all. I did, just out of habit, but found out later that I didn't need to. The side and top and bottom supports are all you have to remove now, to get the screen pack out and dealt with.

If you turn the frame up on its side, so that it will be taller and easier to work with, BE CAREFUL because the screen pack - even as a triple layer pack - will immediately try to topple out, with even the relatively rigid glare screen being very flexible when held in that direction, being in that position a very "leggy" 2 to 1 height to width ratio, at 16x9 measurements. I almost lost it, and it will scratch very easily if it gets away from you and hits something you don't want it touching.
