Or better, an LM adjusted to 3. We believe the communication is the best way to solve any problem. Originally Posted by retiredcaps. Report item – opens in a new window or tab. Watch list is full. I can hack that. Found the answer http: Seller assumes all responsibility for this listing.

Then everything expecting a particular voltage will still get it. About halfway down the page: Skip to main content.

I’ve heard that in some units the frequency is around 60kHz. We respectfully ask that you make some time and effort to read some of the guides available for basic tsp. Who manufactures it for them is the question. The time now is Huntersville, NC My Country: Did you get your power supply working? The switching transistors take the DC power and turn it into a high frequency AC supply. From those and the partial reverse engineered schematic, I see that 3.

What I’m concerned about is any output overvoltage protection. The other transistor in that circuit is probably also blown.

If items become defective in 30 days, We will send you a replacement without any extra charge, or offer refund after we receive the defective item. That’s why I suspect it has something to do with the primaries. Then it will up the PWM so 5V comes out of the 3. When troubleshooting a dead psu, one thing I look for is dsp or not the LEDs on my checker flicker. Add to watch list.

Although the drawing is from an earlier model, the FSP circuit should be very similar. We are not responsible for any custom duty or import tax. There are some schematics on the Internet, but I’m not that skilled at reading them and they are in Russian. Swap the diodes on the erstwhile 5V and erstwhile 12V, because the shottky diodes on the 5V line are rated for more current.

Last edited by selldoor; at I’m not entirely sure that this is what burnt, but would it make sense that this transistor would prevent the primaries from charging up or would it be the bridge rectifier or something smaller like a diode or resistor?

Yes, it’s a prime candidate for a DM mod Learn more – opens in a new window or tab. I thought I’d swap the 3. Page 1 of 2.

So this would be a good candidate for a DM or other pwm chip mod. So here are the voltages I got.
