Screen dimming/fading contrast screen on MP2x with time?

Hi,

	Is a decrease in the contrast of the MP2x screen over time a known hardware problem?  I’ve noticed this a
LOT, and it seems to vary somehow depending on how long it’s been on, I’ve thought sometimes depending
on temperature (hotter=less contrast, darker “white”)  I’m mainly wondering whether I need to
just replace the screen, or whether it might be some resistor or capacitor in the LCD power circuity
somewhere.  I’m always running on adapter power, indoors under normal reading light (100W-equivalent CFL).

Jim

Re: Newton Repair Question

There could be unseen damage. I've seen boards where there are one or  
two visibly burned components, but repairs made to those still didn't  
result in a fixed unit. Oftentimes there is damage to parts that isn't  
visible.

You need a 220 volt adapter...it might have been a good idea to take  
one along "just in case". I wouldn't trust my Newton (or any of my  
devices) to be subjected to a higher voltage, even though it says that  
it will accept it. It's happened to me, and once was enough. I'm  
guessing that's now true for you as well. ;)

Another good idea would have been to make a backup of your Newton  
before trying the 220 outlet. Again, just being more safe than sorry.

Sorry for what might seem to be kicking you while you are down...I'm  
only trying to be of help, not be preachy or take an "I told you so"  
attitude.

Once when I was traveling the plastic clip that held my shoulder strap  
of my laptop bag broke as I was entering my hotel...my Titanium  
PowerBook inside hit the concrete parking lot. I rushed inside with a  
sick feeling and powered it up...it turned out that the screen was  
intact and okay. The left front corner was what hit, and it cracked  
the case pretty bad, and there was a very small dent on the corner of  
the clamshell/display lid. I got the bright idea: that shouldn't be a  
problem, I'll get some slipjoint pliers and gently squeeze it to  
straighten it out.

I heard a crack...guess what happened? That's right, I cracked the  
display. There was now a small one inch ribbon of display running down

Re: Newton Repair Question

Forrest,

You are probably correct and I did put a little to much faith in the
Apple adapter as for years I have read horror stories about 3rd party
ones. I do have a backup a few hours before the incident so I did not
loose anything as far as data goes. I was hope for the off chance the
the problem had been seen before and there was a fix for it.

I was all prepared to send Frank Single Malt Scotch and Wendy's
burgers but I guess maybe I will end up sending it to him for parts
and research pile.

I just hate every time one dies, not that I am a newton slayer but
this is the second one for me that has died the other one just quietly
went to sleep and never woke up. It's ROM board was good and it was
the parts to update this recent victim to a 2100.

Re: Newton Repair Question

You do know that when they "go to sleep and don't wake up"...that sometimes, if you remove the battery and AC
power and let it sit for a few days, it will often restart when power is restored? It's weird how that works.

Happy to see that you backed up your data first. I always say, there are two kinds of people in the world: those
that have lost data...and those that will.

Thanks,

Hello,

>this is the second one for me that has died the other one just quietly
>went to sleep and never woke up. 

I'm guessing that you've seen this particular section of Frank Gruendel's site 
already, but since I never like to assume too much when it comes to human 
affairs, I'll post the link anyhow:

http://www.pda-soft.de/2x00_disassemble.html

Frank goes into the four different types of resets in great detail and invites 
the reader to try them out -before- they embark on the disassembly process.  If 
you're faced with a seemingly "dead" MP2x00, it's well worth taking a few 
minutes to go over the text and follow the steps given.

Best,

James Fraser

Go (game) programs for Newton?

	Any good Go programs for Newton, or would I have to port GnuGo?

Do you use an AC adapter?

Hello,

How many people here usually run their Newton off an AC (mains) adapter?

Re: Do you use an AC adapter?

Hi

When I'm in the office and possibly running NPDS and a wireless card, then I'll run from an AC adapter (a few
hours a day, most days of the week). For normal use on the go, I use rechargeable batteries (usually
Eneloops or the Duracell variant of them). No problems so far with any of the Newts or the eMate, thankfully.

Re: Do you use an AC adapter?

Hey James,

I usually run off an AC adapter and use a battery tray with rechargeables when I'm not plugged into the wall.
