I have a Grace Internet radio powered by it's 12v transformer. A couple of days ago, we lost electricity for a couple of seconds. When that happens, I just turn the radio back on. This time, I got a blue "Grace Digital Audio" screen. I tried resetting it moderately and completely (factory defaults), but neither would get rid of the blue Grace screen.

I contacted the company, and they recommended the two resets I had already tried. "If this doesn't help, the power outage may have damaged an internal component." It's three years beyond its warranty. Could a momentary loss of power have damaged it, considering that it's being powered by a 12v transformer? It lights up with the Grace screen, so something is going on in there. If it's dead, I'd like to buy another, but I'm not sure if I want another Grace.

EDIT: I received another email from Grace. For a flat fee of $32.99, they will repair the radio or give me a new one, and it will have a one year warranty. That's a good deal. I'll find an appropriately-sized Amazon box and send it to them.

I assume it is wireless (WiFi). Some of my WiFi devices require some time before they connect back to the router after a power outage. If you have something like "fing" a cell phone app, you could check the radio's status.

Jerry,

Anytime you have a power lost due to some sort interruption the is a very high probability of damage to the power supply. Usually the diodes or caps. its the surge that does it. When I was in the business we always had a flood of electronic devices come into the shop for repairs more often than not we were able to repair the power supply. Of course if there was a direct lightning strike nearby the device was usually toast and unrepairable.

The power going off causing damage is much less likely than the power coming back on causing damage. Perhaps the fairly ugly waveform on the power line as everything in your home tried to restart, somehow momentarily overwhelmed a poorly designed 12V wall wart and damaged something. Not likely, but not impossible either.

Did you control this speaker through a smart phone or PC link? Does it still connect there? Can you see it on your wifi network?

This is connected directly - by cable, not Wi-Fi. I can't even get the radio to start up, let alone try to get the Wi-Fi connection going.

By "power supply," do you mean that little black brick? That's giving power to the radio, at least enough to get that "Grace Digital Audio" screen lit up. If I can find another 12v transformer, I'll try that.

There are whole house suppressors that can be attached at you electrical panel that will provide protection. Nothing is guaranteed to stop certainly a direct lightning strike but a spike from power coming back on normally does little if any damage. Most spike come from within the home. Surprised? Hair dryers, vacuum cleaners, mixers, drills, all send noise and spikes on the house power.

Being on a cable does not protect you at all. In fact it makes your home more vulnerable to a spike or lightning strike. Dish Network recently had the misfortune to replace 3 TVs, 2 DVD players, and all the Dish equipment in my home because the installer did not ground the cable coming in. I asked him to and he said it was grounded at the pole. Big mistake. The DIsh Hopper system is all connected by the HDMI ports from the hub. ll HDMI ports were blown along with probably power supplies. My internet had only a splitter like device blown because it was grounded and did not make it inside. The Dish hub had a ground rod right there but a lazy installer did not want to cut 3 feet of ground wire and hook it up.

BTW, all wall warts are not the same voltage or polarity on the connector.

In the days of tube radio and tv was told to unplug tv and radio when had a power out. Guess that that is still true today.

Considering the outage lasted about three seconds, that would have been difficult.

Sometimes there are a lot of spikes and bzzorts when power drops or comes back on. It could have been fried.

That, or try another 12v power supply/transformer, just make sure of polarity.

Sounds weird but unplug everything from the unit and transformer from wall outlets. Wait a minute or two and plug them back in see if that works.

Unplugging it to attempt another reset is definitely not weird, it does work in many cases.

My weird electronics story: My "work" laptop would not start one day, screen off, nothing lights up, etc. After a couple hours it suddenly came to life, back to normal. Scary. They bought me a new one for work, and I left the original powered up for about 3 months until I was sure I'd transferred everything I'd need.

After being stuffed under my desk for a month or so, I pulled the original out, and it still wouldn't start. So I googled the model number and "won't start". Come to find out, its a known problem. Solution: Remove power cord and battery, hold down the power button for 30 seconds or more, reconnect everything, and it starts right up. They think a static discharge tricks the internal power supply into a funny mode, and holding down the power button discharges whatever it is, so it's back to normal.

So the complication of today's devices can sometimes be their downfall.

I think I have been set that way.
