When I am turning on my PC only HDD LED blinks for a second, after that no response (not blinking both LED's)? In the above video, in order to make the light bulb glow with this low power SMPS, a 15W bulb has been used, since a 100W one wasn't glowing at all. You don't need to buy a fancy combination unit. Nowadays, an IC PWM controller chip is almost always used.

How To Check Smps Fault

Not only will you be more careless, but your primary diagnostic tool - deductive reasoning - will not be operating at full capacity. You don’t get confuse because there is only one green wire available in that whole socket. Bad connection/cold solder joints - as with all other mass produced power systems (including TVs and monitors), cracked or defective solder connections are very common especially around the pins of high Finally, never assume anything without checking it out for yourself!

I woke up and hit the power button on the PC but no display. Don't assume your problem is complex and convoluted. Faulty regulators IC can happen but it's not very common. How To Check Motherboard Working Or Not There are now many ICs for controlling and implementing SMPSs with relatively few external components.

Of course, you must know the voltage and current maximum current requirements of each of the outputs in order to make a selection. Pulsating: power supply is trying to come up but shutting down due to overcurrent or overvoltage condition. My gigabyte motherboard is running but not giving display.

This is where an inrush-suppressor NTC comes into it's own, even without selecting the type - it will discharge a capacitor almost instantaneously with the minimum of arc-burn on the solder Smps Working But System Not Starting

Flag as duplicate Thanks! If it does, you'll save a lot of time. Since everything runs at a relatively low frequency, almost any scope will do. Check This Out When Q1 turns on, current increases linearly in T1 based on the voltage applied and the leakage inductance of T1's primary winding.
