If you have a VSS 1 and it has worked without issue for a number of years, and then suddenly starts flashing for no reason, then read on.
Last weekend my VSS 1 started to flash a continuous loop of LEDs that had the power LED steady, and then 2 would flash steadily before 4 flashed at twice the speed of 2, then all would flash briefly before starting all over again. You may have the same problem or similar, but the thing to watch for is a repeating pattern with the Power LED steady. The only other LED combination that may work is when the Power LED stabilises and the all others come on and stay on.
This points to a Power Supply problem (the little black brick that you plug into your socket). I did not believe it at first, but it is the fix. You need to replace the PSU a (I got mine for £2.50) and your problems will go away. If you want to know more, read on.
During the power-up/sync process, the SureSignal becomes very power hungry and the current drawn from the PSU a may rise to around 1.1a to 1.2a for a prolonged period. After a number of years (these units will now be around 4 years old) the power supplies simply give up. Some go short and will not power up at all, others will go lazy and not deliver the full current required. The replacement PSU needs to be 12 volt and 1.5 amp output minimum. It uses a 2.5mm female plug to put into the unit itself. You can get power supplies that are rated with a higher current output, but it cannot be below 1.5 amp (1500mA).
If you have been playing around with the VSS trying to figure out the problem, you may need to do a proper reset to bring it up to stability, but in my case I did not. In any case, this is a much cheaper solution than paying out for a new VSS (the route that Vodafone will probably ask you to do).
Wherever I lay my '@', that's my 'ome.
