I checked and this AE chip does not have its activation voltage either which passes through a 10k ohm resistor, i just have the VIN on pin 1
no shorts either

Hello so I checked the 2N chip completely I didn't find any output short and I found where EN1 is connected I switched to diode mode and I have a direct connection with the pin of this IC I don't know what to it is useful I do not have its datasheet but on the second identical IC right next to it I have no direct line for EN2Leave a comment:

Okay thank you for all the details I really appreciate your help it's late at home I'm going to rest and tomorrow I'll give you everything you need, good night sir.Leave a comment:

EN1 : 0
EN2 : 0
LDO3 : 3,3v
LDO5 : 0Leave a comment:

The temperature is around 35 degrees celsius I did not specify but I have already changed the 3v 5v chip without success, ACN and ACP I have 20v here is a diagram of the 3v 5v chip with the voltages that I should have I put a cross where I have no tension.Leave a comment:

all voltages are good ACOK (3.3 volt)Leave a comment:

yes my probes are pointed my multimeter in diode mode and red probe to ground ACP (0.420) ACN (0.420).Leave a comment:

Thank you for your response
The charging chip has the reference (BQ24780S) and yes I use the original power bank here are the photos of the chip and the power bank....Leave a comment:

MSI DELTA 15 NO POWER
Hello I have a problem with an MSI DELTA 15 which does not want to turn on according to the customer he was on the internet and the PC suddenly shut down while it was on battery he then tried to charge but nothing apart from the white charging LED which lights up, after disassembling I tested different voltage and I encounter a problem with the 3v 5v chip which does not receive its activation signal of 3.3volt I do not I have no diagrams or Boardview at my disposal but in my opinion this signal should be sent by the EC chip (ENEKB9028GC) on my thermal camera I only have 2 heating points the 3v... -

Re: Lg 55eg910v oled tv
Hello everyone, I have a fairly complex problem concerning an LG_55EG910V oled television which no longer turns on but the red standby LED is on but no reaction from the LED when I press the power button or on the remote control, I I checked the voltage of P201 on the power board only the standby voltage of 3.5 volts is present nothing at the level of 12 and 24 volt then I checked the main board when I press button one the voltage of 3.5 volts drops which is normal this is the signal it sends to the MICOM on the card it is IC3000 this famous signal is supposed...Last edited by Kevin555; 09-20-2023, 01:53 PM.Leave a comment:
