A weak power supply is the signal I'm getting. One of the first concerns would be to find one or two bad capacitors as the culprit. Always, on the first level of repair is to consider bad caps. Thanks for asking and show a few hands of support!

Ps3 wouldnt turn off. unplugged now will not turn on


how long was it trying to turn off before you unplugged it? it might of being performing an update which can be problematic if you canned the power to it while it was doing this.
you could try a factory reset but you will lose your saved data.

I am trying to hook up to my new comp. and new internet and the lights come on for the wireless, wired and router r green then the modem light is red, what am i doing wrong


There is nothing wrong with your modem. There are modems that when you turn it on, the wireless, dsl lights are green while the power light is red then after a few seconds, the green lights disappear and the red light will turn green. After sometime green light will come back on. This means your modem is restarting and doing a self check.
If the power light stays red, then you a have a problem with your modem.

Green power light comes on for a split second, then red.


The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories

I have a gateway ma7 laptop and press power and get nothing


When the computer is off, unplug the power cord from the laptop and then plug it back in. See if the charge light (lightning bolt symbol next to the led) comes on or turns green/blue. If it doesn't your power supply may not be working, even if the light on the supply is on. Second is the battery may be damaged. Remove the battery and see if you can power on at all.
If it boots with only the cord, the battery is bad/shorted forcing shutdown.

AKAI 32" LCD HDTV WILL NOT TURN ON


The only solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com
