Blue light blinks for 5 secs when i turn it on then goes out....keyboard not working at all

SOURCE: wireless keyboard is blinking a blue light but nothing else is working

Normally Dell keyboard require a wireless uSB plug in that connects to your computer and there is usually a small button on both the keyboard and the end of the connector. Press them both. Normally preplacing batteries causes the connection to be disrupted.

The power inverter is the problem and the only way to fix it is to replace the board. It was a poor design and my Proview 19" experienced the same screen issues as those previously stated. You'll pay $25 for shipping and up to $65 in repair costs. The kicker with Proview is the lousy 1 year warranty. I threw my Proview away and purchased a Hanspree 19" with a 3 year warranty.

There is a 3rd party repair facility in TX that specializes in this type of repair for a flat rate of $75 but that doesn't include your cost to ship and insure it. Another possibilty is to buy the invereter yourself and break open the back and replace it. If you can find the correct part it should run you about $35.

I rank Proview monitors in the same category as the Koss Home Theatre, which is JUNK!

check the bulb door and make sure its closed all the way. be sure the bulb is firmly pushed into its socket. if the problem is still there you may need to repair the power supply board.
