#Monitor woes– Help!
10 messages in this thread
I've been having wierd problems with my A3000 and NEC3D. My example
involves using two screen, a totally black one except for some blue text
from VLT, and a very bright/white one with PenPal. The PenPal screen is on
top of the VLT screen and I move it up and down.
As I move it up the bottom 1/4 of the screen, the top of the VLT screen
begins to warp outward. As I move the PenPal screen up towards the top, the
brightness of the blue on the VLT screen diminishes to near black.
I first noticed these problems with the HAM-E board, but they are
obviously being caused by something else, because the HAM-E board isn't
normally hooked up (flicker-fixer and all).

Have you been plugging and unplugging the monitor cable while the machine
is on? Do you have any big speakers or something with a magentic field
near the monitor?

Steve, both your guesses are possibilities. I have a TV set right next
to my computer. However (I just tried) shutting it off didn't change
things. Then it comes to unplugging/plugging the cable with the computer
on. I'm guilty. I know, I know. I can hear your groans and sighs. 8) If
that caused the problem, what would need to be fixed? Also, what if it is
the monitor?
Thanks,

I'd take it into a dealer and have a tech look at it.

Ethan,
Just before you take it to a dealer, try two things. Move any speakers
away from the area. Move your TV if the first thing didn't help. I
received a new stereo with a great sub-wolfer unit (Is that the spelling?).
I placed it on top of my TV's entertainment center. It was about 2 feet
actual distance. The next day I was cursing at the cheap (no it wasn't
inexpensive) TV for being broken after just running out of warranty. Then
it occurred to me that even without any power on, the magnets in the
speaker was warping the color in one corner of the TV. Whew! cheap fix.
The only things near the computer are the TV and the HAM-E board
itself. I've tried turning the TV itself off, although I haven't turned the
HAM-E board off. The monitor is also 1 1/2 years old. Also, I bought it
mail order, and so most dealers will be unhappy about being shown it, and I
don't know if this problem is worth my spending any money on. I'll probably
just come to live with it.
BTW, I know the arguments pro/con mail-order. I went mail-order
because I saved over $200 on tax. As well, the only other dealer in the
city I'd really consider reputable is Leigh's Computer and their prices (at
least at the time) were out of my range. I felt that I can handle most
problems (with the help of people here) and that if the thing itself was
defective I trust Go Amigo to take it back. Well, whatever. As I say, it
isn't worth any money to me to have it fixed.

Ethan,
I have just bought a Nec 3D and the bottom left corner is not the same
brightness as the rest of the screen. I returned my first one and got
another one and the same problem exist. My Nec 3D is hooked up to a
FlickerFixer and when I had a Nec Multisync II hooked up I did not have the
problem.

That sounds wierd. You may have some strong magnetic field in the
area, or the signal coming from the Amiga may be defective.

This sounds like a magnetization problem. Make sure that there are no
speakers, other monitors or any source of magnetic fields close to the NEC.
Also don't rotate it. Since the monitor has a built in degausser that
operates each time it is turned on, try turning it on and off several times
a day for a few days. There is a good chance that the problem will go
away. If it doesn't, a more powerful degausser may be needed. Any TV
repair shop should be able to do it. Peter.
Ethan,
Your monitor symptoms sound like a combination of problems in the
high-voltage and video clamp sections of the monitor, depending on what you
mean by "warping".
