Hi,

damned annoying. Turned on my e370. Power led lit, CPU spinning but
no monitor display. Changed to a new monitor , still nothing.
Checking monitor connection D plug and a pin is missing, ( other
monitor that works, is still working on another PC ). I suspect that
the Monitor Connection Pin is inside the case monitor connection.

Anybody know where I can get spares for the motherboard, monitor
connection connection assembly for an emachines?

thanks

Davy

If it's the center row of pins...they are all grounds...so a lot can be
missing...

Even if a critically needed pin were missing, your monitor would still
display...
but the colors may be off.

Emachines are known for having a lot of motherboard failures...
but you may want to try another supply or swapping RAM

atr any rate don't waste too much time with it
 
Dear Philo,

yes it is a centre Pin.

Took the motherboard out and I can't access the D pin for the monitor
as it is soldered on to the motherboard.


So it looks like a *u*ked motheboard and monitor cable! ( which means
monitor as it is not worth repairing the cable )

Any idea what type of motheboard I could use as a replacement? Celeron
Processor, PC2700 ram.

Thanks

Be aware that some pinouts list VGA pin 9 as "missing". While the cables
I quickly looked at here, all have pin 9, I think I have one cable here
somewhere (could be on my old monitor) that doesn't have a pin 9. So
if the pin in question happens to be pin 9, then find another theory for
your hardware failure. Missing a pin 9, doesn't mean you busted it off.

It could be there is some other problem, such as a motherboard
problem or a problem with a voltage coming from the power supply.
I don't know anything about Emachine responses, such as whether
the computer case speaker will beep, if you remove the RAM.
On modern motherboards, at least some of them will beep if
the RAM is removed, and in order to beep, the CPU has to be
able to read some BIOS code. Doing a "beep test" helps to
identify just how borked the thing might be. Also, visually
inspecting for leaking caps is useful, if the model is
known to suffer from that problem. Have a look around the
processor area, for leaking or bulging aluminum cylinders
(caps) with plastic sleeves on them. Sometimes, you'll see a
brown stain on the motherboard, where the "juice" has leaked
out of the caps. The tops of the aluminum cylinders should be
flat. Failing caps will cause the processor to eventually
lose its operating voltage.

In terms of updates, you could try something like this guy.
So I'm guessing the processor is S478, and likely a Celeron
1.8GHz/FSB400/128KB cache.

Dear Paul,

I appreciate your help, thanks

1. I'll try the missing pin monitor in a PC that is working, and
that should nail that issue once and for all.

2. I'll take off CPU Cooler and check out exactly what it is (
front of the box said Celeron 1.8GHz!) but a new motherboard seems to
be the order of the day.

Very cheap at

3. I'll take out the RAM to see if it PC beeps.

Does this test if the CPU is working?

Also, What will Win XP do when I install the new motherboard? I have
all the orginal emachines discs and the COA onthe case.

Now I have something to do whittle away those dark winter evenings as
I've never fitted a motherboard.

thanks

Davy

One of the centre row pins is supposed to be missing.
That pin has been defined in the past as a 5 volt
pin , for some dark purpose(its pin 9).
On a flat panel of mine , the full 5 volt was attatched,
and on a p104 computerboard it was fully grounded.
Now that is no problem , when the pin is missing in
the cable, but i happend to find the only complete cable
in the shop. Result: Four burned out ground traces in the
multilayer computer board. I am much happier when they
leave that pin out .
