Your problem sounds very similar to others that have reported bad capacitors with the Slingbox Solo. Very hard to diagnose unless you actually take the box apart and look for bulging capacitors.
You have a few options.
1) Contact Sling Support and see if they can help. You will be charged $30.00 for them to do so.
2) Since your box is out of warranty you can ask them for a discount on a replacement or upgrade.
3) You decide that you want to delve deep into this and try and fix it yourself. If so then you will need some patience for a little trial and error.

It all depends on what you are willing to try and do to resolve this issue.
I can't say for certain but it does sound like an internal problem with the Slingbox. Based on your description and other information I've come across here and elsewhere, I'd be very suspicious of a hardware failure. The post above re: bad capacitors is a possibility.
As a general suggestion I'd say do what you can to ensure good ventilation, try to keep the Slingbox as cool as possible.
Understood Adam, hope it works out for you.
Pardon the unsolicited advice, but...
I'd recommend against picking up another Solo if you replace the one you have. I have nothing concrete to stand on in saying that, but I've seen too many problems with that specific model to be comfortable with it.
The Pro HD appears to be a better product all around.
My 5 years Solo stop working a few days ago with error code 0x923400dc (it's hot these days!).
I find the discussion at
and start check capacitors on PCB. It turned out there are two 470uF capacitors
bulged on top. I got the parts from Radio Shack and replaced them. The box back
to work but not for long. The I checked voltage on board. It turned out it is Solo power
supply problem -- the power output is below 4.5V (suppose to be 5V/4A) and unstable
when loaded. That caused ethernet connection failed and keep reseting. Replaced
it with a 5V/2A power supply solved the problem for now (It runs continuously for
10 hours so far).
This DIY needs some skill on disoldering/soldering parts on fine PCB board.
My experience to share.
