Diode Test Per Hansson you can calculate the output voltage if you can identify the resistors connected between output-PIN5-ground. The time now is Originally Posted by Per Hansson I did check the voltage into the small fet before I lifted it and it was around 4v in and 3.

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.

But now just a number of LED’s get lit when I power it on, filftype they stay that way, no matter if I remove in822 diode or not Never be afraid to try something new.

I hate DMM’s it should read open circuit one direct Very high resistance near short the other actually I think your reading a voltage drop across it or something. Looking for other manual? Como, Italy My Country: Last edited by Gianni; at Ciao Gianni Last edited by Gianni; at I think you have measured wrong values, in the attached pic I see R67 has 3 digit number likeso it should be ohm.


Now it is very late and I must get up within 3 hours 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 inn5822 real diagnostics test, first power turned on then it blinked each port’s light to let you know it was working If the tuner needs to filetye replaced, the complete QT Board must be ordered.

Any PMs asking for assistance will be ignored.

Diode Test Per Hansson ignore the above message The forward voltage that i’ve measured is very close to the nominal 0. Without load I had the output voltage but as soon as I connected the load a resistor the IC has died My board is different from your circuit, it has a monolithic IC, so I don’t know if the behavior it is the same.

I’m sorry it died.

What I can suggest you for future opportunities is to fletype to test the power supply or step-down converter isolating it from the board if it is possible. Diode Test I’ve got a Fluke here in front of me at work, and according to it, it’s measuring volts DC.

Diode Test more importantly what does it say in the reverse direction. Diode Test Google for ij5822 1N datasheet, on the second page, look at the “forward voltage characteristics”. The picture can be seen but jumping double image.

Replaced pages 23,mahual Flickering present in all input functions. And the switching chip becomes very hot, so I think I cooked it. Good tiletype to the repair!
