Have you checked the status of the power supply code?Sometimes the code in some positions may not transfer power to the system.

    To check the power supply code, replace the power input code with a new one and see if the system is powering up.

Hi.

To start the Lifestyle has two parts that are independently powered. If there is no power to the acoustimass (subwoofer), and there is voltage in power cord, then the internal power board in the sub woofer is shot.

If the music centre (the one with DVD) has no power, but the adapter has regular voltage, then:

If there is no power at all, the music centre is faulty. Problem is in the initial circuit connected directly to input. There are a couple of resistors directly on DC line that may fuse. The connector pins may also break.Testing is done at component level.

If the music centre has led on, then the problem is often the data cable from acustimass. If there is any problem with cable and connectors the music centre will stay in standby and not start to prevent eventual damage.

The fans are controlled by the motherboard, not the power supply. Normally the fans will not run and or run to where you can hear them unless the temp reaches a certain point within the case. The computer will warn you if it is overheating.

When the board is powered,it goes off.


hello cyokwueze

usually when a system turns off within a few second it indicates either a faulty motherboard or power supply.
based on what i have seen in the past i tend to say it is the motherboard. what you need to do try a different power supply and if it is still the same it confirms a faulty main board.

good luck

I've just installed a psda400 Diablotek power supply on an older compaq. On power up, no fan and red flashing light. Any ideas?


Get another power supply from another company. I purchased a Diabletek PHD450. It failed out of the box (verified by using known good supply). This was in July 2009. I got a RMA and they returned the same dead power supply with the same problem. After several calls I got another RMA. I returned the supply. UPS confirmed delivery. they still have not sent a replacement. It is now April 2010. When I call the support number on their web site I am given another number - no one is ever there. NEVER AGAIN - DIABLOTEK IS DEAD.

Computer wont boot have steady amber light on the start push button nothing on monitor


check you power cable and extension socket for steady power supply. if it is ok, consider plugging it into another outlet. if that fails, check your memory card. if you have more than one card installed, consider taking one out and restarting with one. if it fails, swap it with othe on and the othe out. if it fdails, take out the C-MOS battery from the motherboard and replace it after 2 or more minutes. restart the system.
