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). — Ethan

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

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, — Ethan

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

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

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. || BY THE **+++++ Judd Pape +++++** BY THE || .

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

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". Karl
