130XE question

[DEBRO]

Hi there,

 

I have a 130XE that doesn't seem to work.

 

I've never had a 130XE before so I don't know what color the power light is suppose to be. It poser ups with a red light. Is it suppose to be red like the XL series?

 

The power light comes on but I have no video Any ideas what could be causing this? I'd like to keep the 130XE and repair it since it has 128K vs. my 800XL's 64K.

Well, I can't help because my 130XE died a month or two ago. I just get a blank screen when I power it up as well. I've tried swapping out most of the major chips without any success yet. Unsoldering those 40 pin ICs is a pain though, I made sure to put sockets in all of ones I tested.

Anyone with a service manual?

Oh and mine has a red power light as well.

FWIW - 64k is enough for almost everything in A8.

Yes the LED assembly in the 130XE is a small red LED with a translucent red plastic lens.

 

The most common cause of failure in the 130XE is bad ram.

 

The absolutely easiest way to find of if its ram is to take a known good 64k ram chip and bend the leads in slightly.

 

Then with the power off, place the good ram on top of one of the possibly bad ram chips piggy-back style. Make sure the leads are bent inward a little so it makes good contact with the chip below on all pins.

 

Then turn on the computer, if it boots you found the bad ram chip. If not turn it off and move the chip to the next ram and try again.

Thanks for the tip, now I just need to find a working memory chip.

LOL! So simple, but I'd never thought of that. Nice tip!
