He has the 453mini .. linked thread already states that there is no header to solder to

Thanks for the help guys, I had a skilled guy add the wires to the chip but unfortunately the unit is still the same is there anything further that anyone could suggest please…

Thanks

increase resistance..others have reported they needed to use 150ohms

btw did you see that the pictured wiring was wrong?

Thank you very much I will ask him to try a great resistance of 150ohms

The connection points that we have tried are correct though? IE Legs 5 and 6 in from the right? Per this file: download/file.php?id=32232&mode=view

[dolbyman]

in the linked post it says between clk and ground ..not clk and 3.3V

[devs101]

Thanks, Im not familiar with electronics unfortunately. Has mine been wired up incorrectly? Could you please tell me what numbers should be connected per this diagram? download/file.php?id=32232&mode=view

Many thanks

[dolbyman]

38 and 48

[devs101]

Okay so it was very wrong in the original diagram, before I go back to the electrician could you please confirm that the attached is correct and that we should try the original resistance of 100ohms then move up to 150ohms if that fails?

Thanks again for the input and hoping to get this resolved

according to the posts, those would be correct.. thats all the info I have

[devs101]

Okay thanks very much for the help. If anyone else reading the thread knows any different could you please chime in. Thank you

I have described in the german qnap forum an alternative how to repair the mini again. You do not need to solder on the ic itself on the back of the board is a socket debug 1
there are the
Pin 1 = 3,3V
Pin 2 = Lpc clk
Pin 3 = ground

in the german forum i have also uploaded pictures

[dolbyman]

Totally forgot about that one .. I even liked the pictures .. sometimes the German and English forum blend together for me

Thank you very much! Very helpful.

This resistor trick worked to get my TS-251+ back online, was able to get everything copied off, and have a new synology (ds720+) arriving today to replace the qnap. This experience just really turned me off to qnap finally.

Yet another qnap TS-451 running full fan.
Used a old 120ohm resistor, worked very well.

Thank you so much for this temp fix.
