yes 2 ohm...i'm going to give up.....why this motherf*ckers voltages are in loop?? and why are them stable if in dfu?
[help] 820-01958 dead: 20v not switching

i understand, but i dont' want to give up....maybe i should open a new thread and write " i don't know the history of this devic: it switch to 20v but it seems in boot loop: what can i check"
maybe restart from the beginning would be usefull...
for example i think i MUST HAVE some power rails before to boot...is it possible that it does'nt boot because i miss some rails?!??!? is it possible that i miss for example ssd rails???
i think i should start from:
PPVCC_NAND_SSD0 (VCC for both nands)
right?
created by u9060...
it is a little bit difficult for me to undertstand how u9060 works...i should have
PPBUS_G3H_SSD0 to have it working right?Comment

What is the resistance to ground of PPVCC_NAND_SSD0?
If the resistance is low then the NAND is defective. Without a working NAND, you cannot complete the DFU. With a defective NAND with a low resistance, the power rail will not operate properly. Each SSD0 power rail needs to be inspected for the same conditions.Comment

PPBUS_G3H_SSD0 is 12,32
pvcssd0_en is 0v
pvcssd_avin is 12,32
PPVCC_NAND_SSD0 is 19k
0,346 in diode modeComment

by sam_sam_samI have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
by sam_sam_samI have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
by sam_sam_samI was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that... -
by double_DDHi all,
As the title suggests, how can I be sure that my EC chip is really dead?
I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.
Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard... -
by sam_sam_samI did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... - Loading...
