Check for short to ground on all secondary power supplies (big coils).
Same behaviour changing charger direction?
I tried with another charger. Right now, there are 20 volts stable on f7400 but there are no 3.3 volts on R1450 as stated on the video. Also, there are no 3.3 volts on L7561 neither. Device's amp stays at 0,02.
There are 8.6 volts on F4800.
There are no 5 volts on L7520.
There are no 5 volts on L7510.
There are 3.3 volts on L7595.
There are 8.6 volts on F4800.
There are no 5 volts on L7520.
There are no 5 volts on L7510.
There are 3.3 volts on L7595.
"there are no 3.3 volts on R1450"
Any resistor has 2 (two) pins.
You should specify where did you check the voltage!
BTW, before looking for S3 and S0 voltages, you need to get S5 and SUS voltages.
You didn't post 3V3_S5/SUS yet.
I can't find L7595 in the schematic...

There are 000.8 ohms on the video but on my board there are 1.7 megaohms. I don't think there is any short circuit here but again there is no voltage on L7520. When I give it 5 volts like on the video, it gets 0.02 amps. There is no short circuit.
Could you show me on schematics what voltage should I get from which part? e.g. "You need to get 5 volts on first leg of c7522. "
What do you mean by SUS voltages? Could you specify? There are more than one hundred labeled SUS... Could you give exact parts and how many volts should I get?
R8187 1-2 no volts
r7110 2- 5 volt r7110 1- 19 voltage
c7002 1- 19 voltage
L7095 1-2 3,3 voltage

You have the board on the desk.
Why don't you specify readings on the real points?
Why should I watch a video instead???
"There are 000.8 ohms on the video but on my board there are 1.7 megaohms."
Please, post accurate information.
Help us first, providing usefull information.

What schematic are you using???

You've already specified something which can help, but I wanted to know where exactly did you measure that.
"Check for short to ground on all secondary power supplies (big coils)"
Maybe not all are really bigs, but you can find them in pages 44-52.
Page 51 showed you many power MOSFETs, where you have to check for short on their outputs too.
"ıt loops on and off"
Any pulse at L7510 at same time?
"You didn't post 3V3_S5/SUS yet.

What about L7560 and U8020?
Be patient, you will understand the schematics in time; just pay atention.

Take your time and reply to all above mentioned...
