Hi, I bought a defective Gigabyte Aorus 1080TI. Unfortunately a chip is missing, see photo. I need the name of that. Thanks in advance. Greetings Christoph -
Hello members,
I have Gigabyte 1080ti Amp Extreme.
It has a missing component near hdmi port as shown in photo. This photo is taken from Zotac 1080ti mini and mini has AAM7MC while Amp Extreme has AAM7MA missing.
I need your help as i searched this component on aliexpress and internet everywhere but I didn't find any seller having it or any datasheet.
IF anyone know about its actual name or marking please let me how to find it thank you.... -

Hi, I'll start by saying that I'm not an expert and I've reached a point where I don't know what to try/do anymore...
Starting from the beginning: I opened this subwoofer for the first time with a very strong smell of burnt electrical components, I realize that on the amplifier board there is a hole between V+ OUT and GND about the size of a finger, the damaged components were the shorted mosfets, two damaged zener diodes and two capacitors. I bought everything, I fixed the hole by cutting the pcb and putting a piece of a perforated board.
I had no problems connecting mosfets and capacitors,...08-27-2024, 12:46 PM -
Board had no history of liquid; unsure of drop history, but no signs of damage of any kind worth noting.
Charger sitting at 5v/0a. PPBUS is at 1.9v-0.9v steady cycle (peaks, drains, loops). Confirmed CHGR_EN_MVR is missing, but DCIN was reaching ISL just fine, so replaced ISL--no change at all. Confirmed pp3v8_aon is also missing--and being unsure *exactly* which signal appears first (or if they are simultaneous), I inspected PMU/U8100 area and found no shorts, but also found PP3V8_AON_MPMU_ISNS_VIN missing (not shorted). Replaced U8100 just in case (have had them fail in weird ways),...
