The troubleshooting techniques you might try is swapping them out with another monitor and keyboard. If they work then you know its the monitor and keyboard if they don't work then the motherboard is bad. The ports for the keyboard and monitor are integrated into the motherboard. So you can't fix the ports, the whole motherboard has to be replaced.

I've changed the belt on my indesit is60v but now it will not start could it be a loose wire? my test pen says power is going from the start button to the timer


Just because power is getting to the switch doesn't necessarily mean the switch isn't bad. It is also possible that the motor or timer is defective.

Ok, I have recently been the fortunate one in my family to be given a Philips proscreen 4600 b projector. The only problem, so far, is it will not turn on, at all...think that's why it was given to me...


Hello, welcome to Fixya!

Your unit is having a power fault because it is not switching on. The unit might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. If it doesn't power on, plug it into another outlet, to make sure there electric current entering into the unit.

If plugging into another power outlet doesn't power it on then it confirms that the unit is having a power fault.

When electric current comes from the power outlet into the unit, it goes straight into the power supply board which then circulates the current into the unit. So if the receiver doesn't power on, the first thing is to make sure there is power entering into the unit.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board. Once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect and solve the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

My Bernina Activa 220 won't turn on. This has happened before, and I've always tried plugging/unplugging, switching outlets, etc. In the past something has eventually "worked" and once...


Could be almost anything ! Do the usual simple checks - fuse in the mains plug (should be 3A), have you got another piece of equipment (radio etc.) that uses the same 2-pin plug for power - use it to check that the mains cable is OK. If the mains cable is OK, it maight be the switch on the power supply module or the power supply module itself ('L'-print), but could be more ... check if the sewing light or display backlight is coming on, but if completely dead, your only solution is to get it checked-out by a Bernina service agent.

My HP a1630n was working fine a few days ago & now it does not even turn on - no fan - no motor, nothing. I tried a different power supply & still nothing. Any clues/suggestions??


Hello,

Try taking out your battery, and then use your power adapter! I just went through this myself.

Your battery may be drained? If your power adapter doesn't work, than you can purchase a universal one, or use the the other you tried. But your battery needs to be out to test this.

My battery was okay, but power adapter was bad...they go bad out of blue for no reason at all! It's fine to use a different power adapter.

Kind regards!

The TV doesn't power on. I've changed the fuse and when mains power is switched on the TV makes a noise as though power is getting through. Pressing the standby on the remote has no effect -...


The problem might be on your power supply section.

1. Check for open resistor or maybe a shorted transistor. Use a multimeter
2. Also check for a leak capacitor

Is the fuse you replace is still o.k? at times the blown fuse indicates that there is a short circuit on your t.v. Maybe the noise you hear is also because of a short circuit. Be careful in replacing fuse, always replace same type for the protection of you t.v

Hope this may help you

Computer will not power up.


Check the fuse, if thats ok then try this -

1. Remove all USB devices such as printers, mp3 players etc etc.
2. Remove the power-cable and the battery
3. Press and hold the power button for 30 seconds
4. Put the power-cable back in but not the battery and none the USB devices.
5. Turn the computer on

Help Please!!! Alarm problem.


Hi.
With everything connected and ignition switched on, check the supply area around the ignition switch. If there is power there, the alarm interrupts the supply after the ignition switch.

Next with ignition on, check supply at the coil input. If there is no supply there, route cable from ignition switched live to coil supply +ve. All other circuits should get this bridged supply and work normally.

Remove any sounder.

If this doesn not work, let me know and I'll go into more detail.

Hope this helps.

More than likely nothing to do with the motherboard.

I have the Thermaltake w0049. and for the money paid is poor quality.
This model and I would guess other models by Thermaltake go belly up if subjected to voltage spikes ie lightening strikes (they are not well protected)
Remove all the leads to your motherboard and join together the single green wire (power select) to any one of the adjacent black leads (ground).
Any atx supply, if connected to mains voltage will not operate at all unless if has some form of load on it. if you do the shunt as suggested(use a paper clip) the fans should spin and you should be able to measure the voltages between ground and the relevant pins.
If you can, plug in a hdd to one of the plugs to give it some kind of load. if you do not know which voltage pins are which on your 20/24 pin connector , then search google for "atx pinout"
