K2 LCD Back?
Locked
 
|
I sure hope I didn't screw up...
The instructions for the LCD display direct the builder to look for a transparent or yellowish protective strip on the back and remove it. On my display there was only a grey strip which was not at all yellowish or transparent. I went ahead and mounted the LCD with the grey strip in place. Is that OK? 73 jim ab3cv __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

I think the time has come for a rewrite of the K2's construction manual.
This question has come up many times and I think that it will continue to come up until there is a change in the manual. I won't attempt to answer it because there are many out there that can do a better job of it than me.

Folks,
Yes, this does come up frequently, and I for one find the manual language quite clear. Please read carefully (with everything in the order stated). "But the back of some LCDs (not all) may have ... If the protective film is found on the back side ... then peel it away" What is difficult to understand about "some" followed by "If" and "then". In other words, your LCD may or may not have the film - If it does, peel it away, but if it does not, do not peel anything away. I fail to understand the confusion, the manual must be inclusive for all possibilities. The language in the manual is the most precise that I know about. Please help me to understand why so many seem to have trouble with it (suggested alternative wording would be most helpful). 73, Don W3FPR > -----Original Message----- > > I think the time has come for a rewrite of the K2's construction manual. > This question has come up many times and I think that it will continue to > come up until there is a change in the manual.

I think part of the anxiety is that it is the first place you come to in
your otherwise straightforward manual that you must make a decision that is not clear cut and does not have a picture to back it up. It is a small decision but as I remember it says "thin film" but be careful not to peel away the backing. At least for me, I didn't know what Elecraft meant by thin film verses backing. Many of us hadn't seen an LCD component like that right out of a bulk box. Never saw one with a thin film protecting the backing to know what one without looks like. What is the difference between a thin film and what is a backing when you've never seen either one and wired up trying to do a perfect job? It is clearly an important step and one you want to complete. PERFECTLY. So ask the reflector. That is why I think you see this so often. Just my .02 cents worth. 73 Dohn N8EWY -----Original Message----- From: [hidden email] [mailto:[hidden email]] On Behalf Of Don Wilhelm Sent: Thursday, January 04, 2007 11:59 PM To: John [K7SVV]; Jim Miller Cc: Elecraft List Subject: RE: [Elecraft] K2 LCD Back?

Yes indeedy - that was one expensive mistake that I made! However,
experience can be a great teacher, if a little costly at times. Now I am saving up my pennies for a replacement K2 RF board .... ! 73 all and have a great 2007.

Didn't mean to stir up such a fuss. I'd never seen the back of an LCD before.

I don't want to over do this subject, but Dohn's comment is perfectly
stated and should be taken very seriously. I'm sure putting a manual together for project as complex as the K-2 is a daunting task. In nearly every respect, the manual is flawless. But this LCD "film" issue is a troublesome one for a first time builder not familiar with these components. I spent a long time anguishing over the question of whether to peal the back off the LCD, and eventually made the correct decision. But as you go along with this construction project, you'd like to think careful construction, not correct guesses, would better assure success. The addenda materials could relieve this confusion considerably with a more elaborate description of this "film." The nature of this kind of project for a builder is that constant perfection is a critical requirement, not a luxury. The manual has to subscribe to the same high standard however difficult it may be to achieve.

The backing film question and how to deal with it was a
matter of concern for me, too. Fortunately, I made the correct "guess" ... 73!

A solution would be for any film to be removed by Elecraft prior to the kits being sent out. This would avoid the need to make any reference to it in the manual. 73 de David G4DMP _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Unfortunately, I didn't. Had to purchase another one from Elecraft.
I built my K2 a long time ago (#2268) and my memory isn't all that good, but it seems to me that the film to be removed was quite thin and clear, like Saran Wrap. If so, what would it hurt to just leave it on? 72, Jim W4BQP On Fri, 2007-01-05 at 15:18 +0000, Ken Kopp wrote: > The backing film question and how to deal with it was a > matter of concern for me, too.

Geeze, I'm not even sure if I did mine right. I looked for the film and
didn't see it. In my manual I have a hand written note that says "not found" at that step. So was there no film or was I just too chicken to remove the film that was there?

Will someone out there PLEASE take a good photograph of the film,
half-removed. I'll be happy to host the photo, as would Wayne/Eric, I'm sure. I have no idea what it may or may not look like. I'm guessing it's like that protective covering on most new electronics faceplates. Not too harmful to leave it there, but prettier if removed - but I don't recall even scratching my head when I built my K2. Years of these messages have reinforced the feeling that "a picture is worth a thousand emails", or some such quote. Email photo direct to me, and I'll post the list with the URL.

I got that one right, but made the wrong guess about the film on the
front of the LCD. I removed the polarizing strip and didn't discover it until I got to the first test where you use the display, which was blank, of course. I immediately ordered another one, but found the removed strip, which was still slightly sticky and put it back on so I could continue testing until the new LCD arrived. It's still there working just fine, several years later. 73 Bob, N7XY On Jan 5, 2007, at 7:56 AM, Jim Campbell wrote: > Unfortunately, I didn't.

I think the confusion arises because even the manual
seems to indicate "some" LCD's, which to me means they must multiple source vendors or vendor types - for this display. Memory (6/2006) seems to tell me there are two (2) films - one of which, IF IT IS THERE, should be removed. I remember, sort of like a lottery - taking one film off and hoping for the best. Apparently I guessed right. WORSE THAN THAT - I then DROPPED THE LCD DISPLAY ON A VERY HARD TILE FLOOR! I then ordered a new one from Elecraft. An analogy could be - if one is holding a hand grenade in his hand, handle held tight against the body - and someone said - "IF there is a ring and pin inserted into the grenade's handle hole, carefully place the grenade on the table". What if there isn't? Fred FL __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Folks,
OK, I believe that some clarification will be forthcoming from Elecraft about this LCD backing thing. Yes, enough builders have had trouble with it that I have come to believe that a diagram or photo or something similar should be added - and I think it will be, but folks will have to heed the info on the errata sheet, and evidence indicates that that information is often overlooked (you just can't win). Actually, I have to say that in all the K2s that I have built, I have never had an LCD with this extra back film, so I conclude that the presence of a film is the exception - but then the situation can change at any moment with the whim of the manufacturer and/or vendor. Thanks for the informative responses. Sorry that I could not see the problem that many of you were having with the manual description. 73, Don W3FPR > -----Original Message----- > > Will someone out there PLEASE take a good photograph of the film, > half-removed. > > I'll be happy to host the photo, as would Wayne/Eric, I'm sure.

I'm doubting this group would have too much sympathy for a builder who
neglects the errata sheet. My first step in constructing a kit is go over the errata sheet and write in the changes to the construction manual. I must confess, however, to having some difficulty reading my handwriting some days or weeks later, but there'll never be a fix for that problem.
