Will not power up at all, there is power in the power bar for other devices on it

There are usually 4 side by side green bars if the battery is fully charged. You can think of each bar as 25% power, so (4) bars is 100%, (3) bars is 75%, (2) bars is 50% and (1) bar is 25%.

shutting down or pausing/skipping/muting, can you just try this and let me know if its is the issue and we can go from there. Sometimes when devices are connected to other device via hdmi or optical they communicate more than sound and video but they actually can communicate "status", to make it simple one device could control another. It is a possibility that the sound bar is being instructed to shut down by another device.plug a device to you sound bar using a rca cable/phono jack(aux cable)if the same thing happens then it is in fact malfunctioning, in which case you should have the manufacture replace it

iPods have no traditional on/ff switch. They power up with the slightest touch, which makes turning the iPod on as simple as touching the menu. Turning the iPod off, however, can be more tricky. Waiting for automatic shut off wastes battery life, and surfing the menus yields no way to stop the device from running. Turning off the iPod Nano, though, is almost as simple as turning it on.

Locate the "hold" or "lock" switch at the top of your iPod Nano. It will be located on the top of your device on the left side. Make sure the device is unlocked. When the device is locked, an orange bar is visible. When it is unlocked, that bar is not visible. The iPod needs to be unlocked in order to power off. Locate the "play/pause" buttons. These are located at the bottom of the control wheel. Press at the "play/pause" section of the wheel and hold for a few seconds. Your iPod will power off. Do not touch the wheel again after powering off, as this will power the device back on. Locate the "hold" or "lock" switch again. Slide the bar to the locked position so that the orange bar is visible. This will prevent your iPod from powering on in your purse or pocket and wasting battery time.

The bar is usually colored red when the device is low on battery power. Some devices have a red bar while in battery use. It should be green when fully charged or charging. I don't know what kind of device you have but that is the usual default colors.

1. unit seems to be in the "test" mode
2. some how it has defaulted to this mode.
3. Disconnect all device to the TV and then power unit on.
4. If tv turns on without color bars then a device connected is the culprit.
5. Try each device separately and see which has a colorbar displayed.
6. if the latter doesn't isolate then it is the unit itself and need a tech to look at the main board for video malfunction -- test

the metrologic scanner you are talking about has a barcode in the maual under the keyboard wedge section it is called stand alone keyboard this will cure your problem when you scan it. the reason being it fools the scanner into thinking there is a keyboard connected. hope this helps Pete
