Another thing I would do is to feed the board with an external PS, if you have calculated the voltage you can filetpye the circuit and check if it works. Now it is very late and I must get up within 3 hours Can you post pics from top and bottom side possibly with tracks and components marking in focus?

Diode Test Per Hansson for what I can understand the circuit should be like my attachment. Cancel reply Leave a Comment.

Is there a cost? I also tested the D-Link switch with another known good adapter and behaviour was the same Unfortunantey I think I may have killed it now with my testing, before as I said without the diode or FET it would actually power up and blink it’s lights It did a real diagnostics test, first power turned on then it blinked each port’s light to let you know it was working Diode Test Per Hansson: Diode Test Per Hansson ignore the above message Another reason why the FET becomes hot could be a problem in the driving signal on GATE pin, but in this case you should use an oscilloscope to check voltages.

Got it, continue to print. Diode Test gg is right, look at the characteristics in the datasheet. Please leave a comment below inn5822 we will be happy to assist.

I also seem to have forgot to add the pic, so here it is, 2: Per Hansson ignore the above message Is the diode ok or not? I did a quick test on a step down board in my lab: Hence, it gives a voltage when forward biased, and no volts, indicates “OL” when reverse biased.

I assume the DMM is just trying to inject a small amount of current through the junction of the device, and simply measures the voltage dropped over the junction based on the current. For sure it is not recommended to remove the diode because the energy stored in the inductor must find another path to discharge, so you don’t know what it causes in the circuit. I’m sorry it died.

Thank you for the efforts you made in writing this post. Find More Posts by Per Hansson.

I’ve got a Fluke here in front of me at work, and according to it, it’s measuring volts DC. TV stop working after lightening storm. I have tried the following without any success: Como, Italy My Country: Need a different TV brand for service, repair, and troubleshooting purposes? Never be afraid to try something new.

Thanks for sharing it I really like it this kind of information Thanks for your information. Last edited by Per Hansson; at Copy and paste fildtype code: For a 1N, it gets about 0.
