I’ve solved it, my Slingbox Pro is now working again …
After searching these forums & the Internet it seems there are an awful lot of Slingbox owners who have experienced identical problems in the last 6-8 months. I’ve no idea why it hasn’t become a prominent tip on the support FAQs.
Universal symptoms are a sudden loss of connectivity, and the network lights going out on the router and Slingbox – leaving just the power light on. On reboot the Slingbox network light flashes five times and then goes out, leaving just the power light on again. Pretty much every description is identical, on Slingboxes that had been working fine and were 2-3 years old.
Many people posted that a replacement power supply solved it, others saying that it didn’t.
So I ordered a new power supply and everything now works fine. I’ve also upgraded to the latest firmware so my iPhone player stops complaining. All fine. It was nothing to do with the Slingbox, the firmware or the iPhone app. Purely down to the power supply.
The confusing part was that the power supply was still able to provide enough power to make a few lights flash, giving the impression all was OK in the power department. But it must have been insufficient to do anything else – and luckily was insufficient for my reset attempts to work, so I still have all of my original settings intact.
It looks to me like a large batch of Slingboxes were shipped with faulty power supplies that systematically fail after 2-3 years.
For those people reporting that a replacement power supply didn’t work, I would suggest trying again. I wouldn’t trust one sent out by Sling Media themselves . . . they might just be recycling their returns. Also, not all methods of transforming voltage are the same – so I strongly recommend avoiding cheap power supplies from auction websites etc.
My original UK transformer says a 6V 3.5A output. The Slingbox spec says only 2.5A, and other people in the USA say their units quote 2.5A. The only other requirement is that the connector is a standard 2.5mm male power plug with positive centre.
If it helps, the unit I purchased was a 6V 3.3A (20W) regulated plug transformer that came from RS Components (http://uk.rs-online.com) part number 445-232 (less than £28 inclusive of VAT and next day courier delivery). It has four interchangeable plates for worldwide compatibility (UK, Europe, USA, Australia pinouts). I specifically wanted my replacement to be a plug type.
Please share this information. I urge you not to part with large amounts of cash to replace/upgrade your Slingbox until you have exhausted the power supply options.
