Yes, it's the first thing that i checked, but the values are ok, one it's 202 2komh and the other it's 103 10kohm (checked on board). I've only 0402 smd resistors and these ones i think they are 0603... -
The diode is ok and i don't find any short

Hello there,
i've got a a grundig high performance cyclone that seem the board doesn't charge the battery. What should i check? I notice that d6 is very hot

So i got it finally!!
The R33 resistor was too low, i try to put a 12.7K resistor but the voltage was low, about 1.3V. So i put a 20K resistor, voltage was about 1.78V, so i reassembled the gpu and mounted it. Now it seems working and i'm testing!!
Thank you all, especially [URL="https://www.badcaps.net/member/427348-%D0%BF%D1%80%D1%8F%D0%BC%D0%BE"]прямо[/URL]!!!So i got it finally!!

I don't think so because the short was only on C82. I've to change R33 and try to power on. With 1.2V the GPU start and the core Is warm, but voltage Is too low and the GPU Is not detected....Leave a comment:

I've measured voltage on FB both on U3 and U4, and both are on 0.59V. Are these values correct??...Leave a comment:

It's perfect, 100 ohm.
Well i've another schematic where R32 it's 499ohm and R33 1K. I don't know how many versions there are....Leave a comment:

VIN it's 12V.
R35 it's 1.2 ohm mounted on board. Maybe it's this one?...Leave a comment:

Yes, i've bought same chip on Aliexpress.
R33 measures 12,8 on the board without R32, should i remove to check better??
R32 it's 10K 1%....Leave a comment:

Zotac 2080ti low 1V8 Rail
Hello
I've got a zotac 2080ti with 1v8 missing, found the problem and changed U3 buck converter, C70, C81, C75, C82 and R32 with the schematic value. Now i start the gpu and i've 1,2V instead of 1,8V. I think that voltage is too low, what can i check?? -
