Re: Xerox 7525 Blank Screen and Energy Saver Button Enumerated Upon Start-up

Thanks... no luck yet. I don't think my series has a SD card in it. It never gets to green screen, you hear a click, a fan spins above the harddrive and I get a number 2 on the LED. The energy saver button is lit almost immediately.

I'm kinda stuck at the moment, but I was off last week, so I didn't mess with it much. I intend to try a couple different memory sticks and see about the AltBoot. I tried replacing a couple fans with no luck either.

Thanks for the advice.

Re: Xerox 7525 Blank Screen and Energy Saver Button Enumerated Upon Start-up

have u tried doing special boot then do the altboot. Always work in my cases

I will give this a whirl. Where can I find instructions on this, I don't see it in the manual and I'm unfamiliar with it.

Thanks for the advice!

Thank you so much for the advice. I received some advice somewhere else that said this slot you are speaking of, WHICH IS ABSOLUTELY PRESENT and doing exactly what you say it is doing, was not what you (and I first though) it was.

So, if I understand you, I need to order the object that is like a microSD card, item #960K58091, and then go from there, and then perform the AltBoot?

One other thing... my LED just stopped displaying the number 2 altogether now that I started working on the machine again today. Should I ignore this new issue and just grab item 960K58091 and continue forward? This machine has proven that I truly know nothing right when I was at a place where I was getting confident with my knowledge set.

Thanks again for the detailed response. I appreciate any and all advice. It's people like those in this forum that truly give me faith in humanity as dumb as it sounds, because we only see and hear the bad stuff about people, but when you look for it, you actually see people are more likely to help others when they can instead of turning their backs on them. Thanks so much! I'm so ready to be done with this thing.

One other question, if you don't mind, where would be the cheapest place to buy this part?

Got it. So, I should get a new flash memory. I thought you meant the microSD or Sim card piece, thanks for the clarification. There are two memory sticks, one that is up higher by the HDD and is 2gb, and one that is lower and is one 1gb. Also, there is the backup battery that is the lowest on the board and is below the fax card (which I checked the battery component and it had the proper voltage).

The only place I can find the part you indicated (by using the part number identified) is here: https://www.iteminconline.com/960k58...module-oem.htm . Unfortunately, from the image on that site, I cannot tell which memory stick or type it is.

Here is an image of the Board:

Page from the manual itself:

From googling flash memory module and checking for the part, the part looks like the memory with the backup battery, see here: 960K73451 - Memory Flash Module (NVM Board) for Xerox(R) WC 7525 - 7556

So, part with battery backup, or one of the 2 Ram pieces?

Thanks again, and I'm sorry for all the questions!

Ok, typing this quickly, have to get going. A few things:

a) Yes the card with the battery on it. WOW haven't seen this configuration in a while but it is very similar to the older 56xx/57xx series B/W machines.

b) After digging in a little deeper, I feel that there is a distinct possibility that the LVPS (Low Voltage Power Supply) may need to be replaced. I copied a few documents outlining this situation but I cannot send them without editing first.

c) When all is said and done, keep in mind that there is still a possibility that the SBC died. If its anything like some of the more recent models, its possible that the thermal paste between the processor and heat sink wasn't making good contact, so the processor overheated and fried.

d) I tried to attach a PDF with some LVPS diagnostic info but not sure it worked. Other docs will need editing and I'll try to PM them to you vs public post. Probably not until tonight.

Gotta go!

I know this is an old thread, but my Xerox WC 7525 has this exact problem. I was wondering if it ever got resolved?
thanx
