The start of a LONG Fuel repair thread...
#16
RE: The start of a LONG Fuel repair thread...
Okay...a lot happened today and I still haven't yet placed a DVI monitor on the Fuel and done a Full online pwr up to PROM yet...

I went through 4 items today.

I finished repairing/replacing the three DS1780 ICs on the mainboard.  That went VERY SMOOTH, I had the right equipment and my only issues were getting good alignment and tacking of the IC accurately.  Otherwise...a breeze!  However, all the old/removed ICs tested good on the curve tracer!  That's not good!!!

OK well I replaced them anyway, reinstalled the board in the Fuel...NO CHANGE...SAME PROBLEM...ARRRGHHH

Well...many swear words later....the errors say ODYSSEY, and so I'm going to replace the DS1780 IC on the V10...why not...right?  OK, Done..replaced and the old IC did measured shorted in circuit, so we're on to something!


Reinstalled V10 into Fuel...WOW there is a difference:

001a01 ATTN: XIO 12V bias low fault limit reached  2.688V.



001a01 ATTN: brick auto power down in 30 seconds

Wow, it worked I'm good....Wait...what this ATTN?  Darn the 12V XIO is being dragged down, I cannot see that on the ENV but I believe it's real...because I just replaced all the ICs!  Okay, so the V10 has a shorted rail...hmm...how should I deal with this?  Well the DS1780 that was installed on the V10 measure shorted between VCC and GRD on it's pins WHILE installed...remeasured...it's still shorted (only in DIODE test mode, not shorted in Ohms..~40 Ohms)...but DS1780 IC works now at the low voltage!

Okay, well I cannot find another VCC line that I KNOW is a VCC and shorted, because the V10 PCB layout does NOT help me see the power rails/track easily...weird.

Okay so I went ahead and injected 1v @ 1A between PCB ground and the VCC pin 9 on the V10's DS1780 (thank god for SGI test points!, they surround nearly all chips and allow easier testing!), I see a direct short dragging down my bench DC PSU, Okay let's follow that.

I tried injection three times with the same values and my thermal imager COULD NOT see any real heat bloom...it might be under the heatsink but it's not near the edge of any heatsink, I decided to bump the voltage injection to 1V @ 1.5A.  Nothing, short is gone....again...nothing short is gone...darn!!!!

This is the second time in recent memory that I did a very conservative LOW VOLTAGE injection with what I feel was a LOW current limit...and the short burned itself out!!!  There like an 80% chance, in my head, that the shorted component is just a passive (cap or diode) used for protection/decouping or whatever.  So let's try it anyway...new diode mode test reading is high ~0.98v instead of the old 0.004v I was getting at the short.

Threw it back into the Fuel:

001a01-L1>pwr down

001a01-L1>


12 XIO Bias is sticking at 11.88v...it's not going lower and the system is still happy...fans are running...it wants to pwr up. I'm not seeing any ATTN Alerts anymore, voltages are stable.

So I turned it off at this point, I have stuff I have to do to prepare for a contractor tomorrow (shouldn't take long) so I'm stopping for now.

Still no idea if the V10 even produces a picture at this point but what has been learned?  The mainboard DS1780s were fine, V10 was draggin down the XIO 12V line from an ACTIVE SHORT, this is was in tandem with the DS1780 on the V10 shorting out or maybe because of it.  The new DS1780 IC wasn't shorting out and could work at the lower rail voltage as it take like ~2v-5V variable VCC input to run.  Again, I have no cause and effect order and I couldn't find WHAT was shorted out, but it burnt out during testing...which means it was likely something the size of a period on a book page to burn out immediately at 1.5A @ 1v.

I give about a 75% chance it was just a decoupling cap or something harmless.  The system now thinks everything's good (comm-wise and voltage-wise).

I've reassembled the Fuel and will then get to setting it up with peripherals and an Irix 6.5.30 disc 1 to try to boot to PROM screen, then try to run IDE diags from CD (I think I can do that manually from boot -f stand?), anyone want to give me a good hint and how to run the EXTENSIVE diags from PROM using the install media so I get this testing underway (assuming any picture shows up at PROM).  Also, yeah I may have to use a terminal for the extended test on graphics...I just don't have a good way of sneaking the serial cable out of the case with the side panel on...any suggestions?

I think things are looking up!  Comments?!?!
