Somehow i managed to get a "new" board, customers bought it. And now when i connect the CMOS battery for the first time and battery the laptop turns on automatically (this is normal). And everything is working everything is ok until i shut it down, after you press the power button nothing happens. I check pin 7 on the keyboard connector and it is at 3.3V, pressing the power button does not change the voltage on that pin. I try manually short this pin to the gnd but the laptop still does not turn on.

Really? Hahah. The problem is I am from Europe and I need to pay an import fee when buying from the US. So on that price, my customs will charge me like 20-30% on top.Leave a comment:

thanks, so I am checking model Nano 200 and it has res. 200x150 and sensibility of 35mK, and this Chinese thing has 256x192 with 50mK. One thing is that Seek offered to buy macro lenses and for this MILESEEY I cannot find anywhere (maybe it is compatible with other manufactures. I know that Seek is well known company so I am not sure what to do here :-(Leave a comment:

Hi, i did not understand your question, on the IC you have 8 lines. I am using [URL="https://www.aliexpress.com/item/33034006982.html?spm=a2g0o.order_list.order_list_main.346.7d1f1802hYfVIv"]this[/URL] connector to connect the ic with my programator.Hi, i did not understand your question, on the IC you have 8 lines.

If you have a lupe or microscope do a detailed visual inspection of the board, search for burned components, maybe some physical damage or water damage....Leave a comment:

Here is a better picture of that X1 diode (it is 1mm x 0.5 mm), i am not sure if the 5V Zenner diode will do the work, or if there should be a diode with higher voltage....Leave a comment:

Update:
I disassembled the PC and inspected MB under the microscope, i found that 2 diodes were broken and i found short around U10 IC (WGI219LM) this is LAN IC. I try to inject 1V and see that this IC is getting hot. I removed it and the short is gone, now the PC is working fine except the LAN is not working. There was probably an electrical shock coming into the PC from LAN (maybe a thunderstorm).
Can you guys recognize the 2 diodes (SOD-923 size i think) that have the marking "X-1"?
Also, I have checked the "KFG" component and there is no short even it...Last edited by rtstorm; 09-17-2024, 05:03 PM.Leave a comment:
