Hello dear Nview Spectra C Owners.
You are my really last hope.
I live in germany and got an Nview Panel last week
from USA for 250$ incl shipping.
It should be ok and the pictures are fine in Ebay.
I got my OHP for 2 days and happy i placed the panel on top.
Then comes the great shock.
Stripes , many stripes.
You know those stripes where i found the warnings before.
"Don't buy such a panel"
So, because of the distance to USA i cannot send it back.
So i take seat (2 days ) and did a repair job.
Yes, i repaired my LCD Display.
There are Chips on film ( from the LCD glass to the PCB )
These vertical film teared of because there is some force
on it the whole time.
You can see it in the attached picture.
Soo after 7 hours soldering the stripes are gone.
It boots all the time and all lines and column are now at
the right place.
There is only one problem left and now i need help from
someone with a working "Nwiew".
The problem is that the Windows Desktop looks quite fine
at 640x480 / 60Hz on three different PCs.
Two PCs running XP and one with WIN95.
But if you look at a JPEG or an DIVx Video the colours are
not natural. I can not explain this in english but see these
link. It's quite the same look
http://www.diyaudio.com/forums/showthread.php?s=&threadid=6248
There are three different things i had to know to find (perharps)
the other hardware damage.
First:
Take a look from the bottom of the panel through the glass.
There you can see three DIP switches
In the Picture at left upper corner you can see my settings.
Are they OK. (Someone tried a repair job before so i'm not
sure if my setting is still "stock" )
Second:
Now for the courageous. You have too loosen only 6 screws
than you can take the cover from the panel away.
Nearby the VGA connector there is big CHIP (U35) with a stamp
"LM1203 N" on top. It's an RGB Video Amplifier and the only
IC in my Nview which gets really very hot.
After 3 seconds i had to take my finger away.
So , if your chip LM1203N is quite cool when running
then perharps my chip is damaged and i had too change him.
( i can get this chip but i had to be sure )
If your's is also hot then i have another problem.
Third:
The one connector from the LCD to the mainboard (JP1) has
two rows. The row which faces to the connectors and to
an "?? EMPTY ??" DIL socket is that where you had to look.
( is your socket empty too ??)
The second connection from the left in this row is empty
and i have one wire which is not connected.
Is this normal or a problem. I don't know.
For tests i connected it but there was no difference in the picture.
Please, i'm very desperated and i need someone which
can take a look at this three points.
If someone has another idea what's the problem it would be
still better.
If you need better pictures i had to email because i cannot
attach more then 100k
So now hoping that someone finds his screwdriver ......

Rainer

I have a spectra pro which is similiar to the spectra c, do you have the remote? If so is there a button that says TEXT, try hitting that it supposed to sswitch the panel from text mode, to vga graphics mode.

Remote
I have a remote. (Viewframe Spectra C)
But there is no TEXT button.
The Buttons i have ......
Reset (these 3 for calibration mode)
Focus
Palette
Contrast +/-
Color +/-

LCD ON/ OFF
< Hor >
Up Vert Down
OHP ON / OFF
That's it

On mine if I hit the pallete button on the remote it switches between the two color modes, the one mode looks just like that picture, I don't know if theres any way but the remote to change this, if you don't get the green light on the front to blink when using your remote I don't know what to tell you, Good luck!
Remote
I had to press
Reset, Focus and the Palette to come into calibration mode.
( then the green led blinks !! )
With the COLOR (left, right) i adjust "9th pixel drop"
With the TINT Button i adjust the Phase.
To exit this mode i have to press RESET again.
But with these options i also cannot get a better picture.
Hope that helps anyway.

Info
Now i have soldered out this "HOT" IC.
LM1203 N and placed a new one in.
Unfortunately it was not the problem and it is normal
that it get's hotter then the others.
The Datasheeet says -> Power Consumption = typ. 2,5W
So now it's even more important that someone take
a look through the lower glass of the Spectra where
you can see in the edge the three DIP Switches.
(That's without screwing !!! )
Please take it only in your hands and look through.
Without the Datasheet from that Sharp Panel (LQ9P011)
i can't go further. 20 switches = 2^20 = 1048576 possibilities.
I attach a better pic of the switches.
Thanx all for your help

Re: Info on Nview Spectra C
Rainer,
I also have the nview Spectra C panel. I looked at the dip switches on my panel, and they match the settings in your picture exactly.
I also checked the connector from the LCD to the mainboard. Looking from the bottom of the panel, the second slot from the left should NOT be empty. In fact, it looks like it should be connected to the wire that is loose in your photo.
Sorry I don't have better news for you.

Thanx for your great help Devorama.
Very nice
Unfortunately i have now no more idea's left
and it seems that i have only a bunch of scrap
here at home.
Now i will have to wait until there is money enough
to buy a new TFT PC Monitor.
I will try this 15" on OHP way.

Another option...
Here's one thought that was in another thread about this problem.
Maybe the problem is not with your panel, but with your video from the computer?
Some computers have problems when outputting high-color at 640x480 resolution. You might need to update your video card drivers so that it can have 16 bit color at 640x480.
If you want to test this problem, try running your normal computer monitor at 640x480 and seeing if you have the same color problem.
I might be completely wrong, but it's a shot in the dark. Hope you get it fixed.

Color Option
Before i post my problem i have tried 3 different PC's
One with Windows 95 and two others running XP.
I tested color depth from 8, 16, 24 and 32 Bit
on every PC but it was always the same picture.
( always 640x480 at 60Hz )
And in this 3 PCs i have always another graphics
adapter. (Matrox G400 Dual Head, Bangee and in
the old Laptop i don't know)
I had always a normal VGA monitor attached so i
could see that the picture and colors are fine.
So it seems that this can not be the problem.
Nevertheless thank you for this hint

problems with the spectra
It also could be the powersupply as well as the cable
1) is the cable (from pc to panel) an original ? if not check the soldering and let me know what number of the vga is connected to the wide connector.
2) if the powersupply goes under 11 volts and it needs at least 1.6 amp - the facotry says 1.9 A you might have problems as well.
Also what is the length of the cable. If it comes straight out of a pc, the best is that the cable should not exceed 10 ft. if it is a good quality with harness, then you could get a bit more.

It would seem that I'm having the same problem as Rainer with my Nvew Viewframe TFT. 2 stripes scrolling down the screen, each with 1 bright white and 1 black bar, together the two take up 50% of the screen. In front of a really white background (like Device Manager), the stripes become nearly invisible, the white one seems to turn very light purple and the black one disappears.
The bootup screen has no such stripes, so I think it's the cable. It looks like a third-party cable.
Ok. 1-6-connected. 7-8 not connected. 9-connected. 10-not connected. 11-13-connected. 14-15-not connected.

it is not very clear what wires you have connected
but this is for the spectra C!
pc OUT................... analog panel IN
db 15hd male .......... db 15 female
1.....................................7
2.....................................4

and ofcourse the ground to the metal outerpart

i double checked it, i make these cables often!!!, this is the correct wiring.

uvodee can I get your email addy? If you live in Washington then it might be that I'm using one of the cables that you built (and just got in the mail on Monday-I think Verbose Mustafa ordered it), and I'd like to verify it. I'm trying to figure out just what part of the panel is causing the stripes.
I have no way to verify that diagram, because I can only open up the female connector, not the male connector. I was just telling you which of the female connectors are being used.
If this isn't one of your cables, then I think I'd like to buy one of your spectra c cables to test on this panel. Who knows, with the proper cable the stripes might go away.

Cabling
Hello Uvodee
I have an original cable which an Nview Emblem on it.
I have checked your cabling also twice and it would be
the same if you begin to count in the upper left corner
from both connectors.
Then it's the same and my cable is well right.
When you look onto the small numbering prints of the
connectors you can see that the 15 Pin VGA Male begins
in the upper left corner, while the 15 Pin Sub Female begins
with "1" in the upper right corner.
So for example your
db 15hd male .......... db 15 female
1.....................................7
..... is a correct 1 ..... 2,
but the "7" seventh from the left
This in mind all your given connections are ok and it's
not my problem.
The second reason why it has to be ok is that the
VGA Loop Through where i attach a VGA monitor
as well would then also get the wrong signals
when my cable would be bad. But the picture
there is always fine.
Power Supply.
I attached for test purposes a Labor Power Unit
where i tested between 10 and 15V DC.
It makes no difference
Thanx for your help.
Keep On 🙂))

yes, I see, it is the one i sent directly to you.
that one was tested, so the cable itself should not have any discrepancy.
let's look at other possibilities!

yep, you start counting from the left upper side of EVERY connector.
When you finish the line, you go to the next one and start counting again from the left, and so on.....

New Infos
Perharps this is interesting for someone who want to repair
something or to bring some light into the question
"How much color can this Nview Spectra in reality !!!"
It seems that there are a few different versions from
this Spectra purchased. When i look from behind at
the connetcors then the power connector is on the right,
and the VGA connector is on the left side.
It has no video input.
On the front is an onprint "Viewframe"
Inside there is a LCD Panel from Sharp with the following
onprint "Sharp LQ9P011"
And about this one i want to talk about......
So after thousand emails i got a datasheet for "my" LQP9011
This are the facts about this display !!!!!
8,4" 640x480 (350,400 und 480 line mode possible)
512 colors, 9 Bit
Each color is displayes in 8 gray scales from
3 bit signals input. Arrording to the combination
of total 9 Bit data, 512 colors are displayed
Response time = typ 80ms (30ms rise, 50ms fall)
Horizontal reverse (rear projection via DIP switch)
Transmissivity 5.8
My Comments:
I think with dithering you can get 4096 colors.
But how to the hell can i get 1.4 Mio colors from a 512 color
panel.
So and those who say that this panel is pretty fast.
It seems that typ 80ms isn't as fast as thought.
** Please can anyone verify what panels inside your Spectras **
I need to know for sure if this is the standard LCD from Nview
or if there are different models with different LCD panels
outside. That would declare the different color statements
i have found.
I have no host space for this datasheet online.
But If anyone want it i can email the datasheet
with all infos about pinning. It's about 600kb
and is from 18.Sep.1992 and inludes 15 pages.
best regards
Rainer

Repaired
So, now my DOA panel runs fine.
It's repaired.
You get these unnatural colors if the display chip is damaged.
I had all rows and columns but the colors are really unnatural.
So, after sure that's the problem i have tried to get a
replacement display. It's an Sharp LQ9P011 which is inside.
It's hard to get .............
But what's easier to get is an Sharp LQ9 "D" 011.
This is a backlighted version.
So i teared it apart and changed the enclosure to the
old "P" type and removed the backlight.
Voila, all fine, it runs now without any problems.
Thanx again for all your help.

I did one mistake.
I wrote here that this LCD has 512 colors (9 bit)
This is still correct.
I didn't understand immediatly how you get
1.3 Mio colors with so few colors with this LCD.
Now i will correct my error !
It's 512 (R) x 512 (G) x 512 (B) = 1.3 Mio colors
