DSR6000 startup looping problem
(Click here to view the original thread with full colors/images)

Posted by: JaO

I have a Philips DSR6000 unmodified.
I've run through all the forums trying to find an answer to my LOOPING problem. I've tried everything suggested (changed drive cables, power supply, hard disks, re-ran 2.5xtreme, etc.) to no avail. So here are a few questions for the techs on this site:

First, does anyone know how to fix this symptom?
Does anyone know the initial load path from the drive to Tivo? Does it go through the Flash Memory? If so, where can these chips be found? If others have had this problem repaired, where can I get service and what's the estimated cost? Can I purchase a replacement mother board? Where can I find one used (cheap)? Thanks for your help.

Can you be a bit more expansive about the nature of the problem - LOOPING seems a little terse.

How far does it get before it reboots?

Does it do the same thing with no drive plugged in?

The "powering up screen" continues to reboot. Every once in a while the "Almost there" screen pops up for two seconds before it starts over from the beginning. Any ideas?

That might suggest a drive problem rather than a boot PROM issue. 'Almost there' is displayed as part of the Linux boot sequence, so your PROM has successfully loaded Linux and rc.sysinit has started to run.

Have you tried a known-good image (maybe a 2.0?) on the new hard drive?

Does it still reboot with no hard drive plugged in? It should stick on 'Welcome' in that config, I think.

I switched drives and installed 25xtreme. They work fine on my other unit but not this one. I know very little about Tivo circuitry but in another life I designed computer items for the old 8 bit units so I know a few basics. I can't help but think the flash memory is involved but I can't tell you why.

Do you not agree that a PROM that can boot Linux some of the time is probably not faulty? Even the most modern PROMs can't repair themselves!

I would definitely be thinking intermittent fault with the power supply - you might want to talk to weaknees about it.

Well, I'm not going to rule anything out including the Prom, but it NEVER boots completely (seldom past the WELCOME screen). I already replaced the drives and power supply. I think I'm ready to get a new mother board if anyone has one for sale...cheap.
