Same problem u had

Sounds like a run capacitor for your fan motor you can the motor trying to run. unplug the unit and look for a silver round can this will be located in the electrical box. ON the silver round can there will be a uF on it you need to go to a air conditioner supply company and get the same one. ON the top of the capacitor it will say com, Herm and Fan. wire it the same way it comes off the old capacitor. You can test it by take a screw driver and spinning the blade if it starts up you have a bad capacitor.

The black plastic capacitor is the compressor start capacitor, it is only in the circuit until the compressor gets up to speed. The black box is the start relay, it stays closed until the compressor gets up to speed the opens taking the start capacitor out of the circuit. The wires should go from it to the small metal round capacitor and the black box.
You can Ohm out the start relay, it should be closed between Terminals 1 and 2 and the coil is from 2 to 5. You can also check the 2 capacitors, you need a Volt Ohm Meter that has a capacitor testing scale. The microFarads should be on the capacitors you will need to cut the bleed resistor on the start capacitor before testing it.

You have one or more blown capacitors inside your monitor. You need to carefully take it apart, find the bad capacitors, remove them and solder in new ones. They are not difficult to find, as they are supposed to be flat on top, but the blown one(s) will be round on top. If you go to Youtube, you can find some excellent videos on how to take apart your monitor and replace the blown capacitors. It is not difficult, nor expensive, and once you do it, your monitor will be as good as new.

There are some worn out capacitors in the power supply. Most can be visually detected by looking at the tops of the round metal cans. If they are not flat on top, then it needs to be replaced.

Try [email protected] They helped me very well.

Replaced that two capacitor maybe its faulty already that is the common cause the trouble there are three capacitor of that unit check the other one.

Good luck:

Dont forget to rate:

the most likely cause is bad capacitors or a fuse in the power supply board.
Dissassemble it, its not very hard, and get the board out so you can see the round barrel shaped capacitors, if you see tops that are rounded rather than flat, then they are bad.
These can be replaced rather easily, there is a complete set of capacitors on eBay for about $12, individual capacitors are much cheaper from mouser.com, but you have to pay shipping, so the ebay item is probably the best bet.

The capacitor is most likely an electrolytic type, these are a round cyclinder device and they are polarised. From its location near the power jack it is most lkely more than 50uF and more than 20V. The information on the capactance and voltage of the capacitor is printed on the capacitor. If you are going to purchase a new one, make sure you get an exact replacement because if it is bigger in value eg. microfarad and voltage it will be too big to fit on the motherbard and if it is a lesser value, it will fail and not perform as required.
The capacitor is polarised eg + & - legs on the capacitor and these must be soldered in the correct direction on the motherboard, the white stripe on the capacitor marks the negative lead of the capacitor.
If the capacitor fell off during de-soldering of the power jack, you must have applied too much heat for this capacitor to fall off. If the capacitor is not damaged you could solder it back on the motherboard.
You should be using a temoerature controlled soldering iron, applying excessive heat to a motherboard can damage the motherboard as these boards are multilayer boards, there are circuit tracks on top, below and in the middle of the board. make sure you don't put solder across printed circuit tracks, carefully check the motherboard under a magnifying glass.

I bought mine off Ebay.I had to replace one on the board that goes to the screen to light up the bulbs,and a couple on the board with the power cord. Usually the tops,or bottoms round out on bad capacitors,and they have some liquid that leaks from the vents on top.Can you send a picture of the boards?If so,please send them to [email protected] I hope this helps.If you have any other questions,please let me know.Thank You very much!

Hi, have you used the same motherboard in the two towers? sounds to me like you may have a couple of faulty capacitors on the board. Open the case and study the capacitors closely [with a magnifying glass if need be] capacitors fail very often when heated. they are the round components that sit in sets of 5, 6, or more in a row on the board. if any are bulging from the top or bottom, then its time for a new board.
