Half Dead Atari 65 XE?

Recommended Posts

Just got an Atari 65XE (PAL) computer.

 

Problem is, the power light glows, but the computer don't really seem to fully power up.

When I first got it, I tried to tune it in with RF, and got nothing at all.

Tried it on another TV, and nothing.

Not even the faintest sign of a signal.

 

I got the Scart cable in the mail today, in the hope that only the RF is dead,

But nope, nothing. No sign of life at all.

 

I don't know if it's the power supply, not giving the computer enough juice, as the red light isn't as bright as I remember, on my old 130XE.

Or if something isn't delivering the power, all the way through, inside the computer.

 

Any has a similar problem?

Oh yeah, plenty of people have very similar symptoms.

 

First thing you should do is measure the power output

of the power supply to eliminate it as a serial computer

killer. It is a common problem.

 

In the meantime don't plug it into anything valuable

until you get a voltmeter and can measure the voltage it

produces.

 

If it is bad, you'll need to replace it with a good one

so the voltmeter will come in handy testing the replacement

first as well.

 

Your supply might be fine and it was another power supply

that went bad and ruined one or more RAM chips by shorting

them out from excess voltage from the bad power supply.

It is such a common thing to happen one really needs to start

here first.

 

Watch how Jon uses alcohol spray to find his extra hot

Ram chips in this video. The shorted RAM chips will run

extra hot and can just be replaced to get a completely

working fine computer again.

 

 

 

If your power supply voltage is near 5 volts and your RAM

chips evaporate the alcohol at about the same rate, then

we can begin to explore other issues with the use of special

carts and other avenues. Are you comfortable using a

voltmeter and/or soldering iron?

Thanks for the info :)

 

I got to borrow a power supply from a friend, and the computer works fine now :)

Going to let him take a closer look at my power supply, and try to fix it.

Hopefully it's just some bad capacitors.

Otherwise, I'll just buy another one.
