Cable Cards causing S3 reboot

Woke up one morning to my Series 3 in perpetual reboot. After some troubleshooting, found that I could boot with cable card 2 ejected. Ran this way for a few weeks then tried re-seating CC2. Unit instantly rebooted, so I ejected CC2. However, it will now only boot if BOTH CC's are ejected. As soon as either is inserted, the unit perpetually reboots. I've tried all combinations of cards/slots with no success. Read that this could be a sign of a failing hard drive, so I made an image and replaced the hard drive but still have the same problem. Afraid it's either a problem with the cable card chassis or on the board somewhere. Got a lifetime subscription on the unit, so I sure would like to get it running again. Anyone experienced this problem and repaired it successfully?

The more things you add that need to be powered, the more power is needed.

When more power is called for and that causes a problem, suspect the power supply, especially since S2s and S3s are known to have power supply problems caused by faulty capacitors.

Fortunately it's a relatively cheap fix if you know which end of a soldering iron to hold.

Thanks for the tip. It does look like the tops of three different caps are bulging a bit. Will replace each and post a reply with the results.

Be sure to educate yourself about the need to use low ESR 105 degree replacements of the same microFarad (uF) rating and the same voltage rating or the next one higher, and of course the need to get the polarity right.

Done deal. Received the replacement caps, replaced and I'm back up and running. Thanks again for the advice. Knew how to solder, but troubleshooting is a whole different ball game. Hope this thread helps someone else down the road.

TiVo Community rocks!
