I have the above mentioned MBP, quick scan with thermal camera revealed that only U3200 was heating up. I found that C3208, C3219 and C3205 were all reading ~6.8ohms to ground.
so I swapped U3200.
I connected the PSU again for a quick check on thermal it's drawing about the same amount of current but now I'm seeing only heat radiating from U7800 and the T2 chip from under the black shielding fabric, and the bottom of the board.
It's hard to judge the actual temperature without removing the shielding.
Does anybody have any insights?

Hi Folks
I got an ASUS ROG MAXIMUS Z690 HERO mainboard with missing components on the backside near the HDMI output.
Unfortunately there is no documentation available nowhere for that board, I did also not find any similar ASUS board design. Even Russians nor Chines have anything available here (nor BV, nor schematics), so only way to discover the parts is from a real physical board.
On the picture left the area where the missing componets are is shown.
On the right picture the detaileed view is shown.
It seems that a double mosfet is missing, probably...Today, 04:46 PM -
Hi All,
I have been struggling to repair a HP 8460P laptop. Motherboard does not turn on. I have traced the problem to what seems to be a missing signal KBC_PWR_ON causing Trip2 on IC 5006 (TPS51123) to be activated.
The following components have been replaced but the problem remains.
C5191
C5192
U50006
Listed below are voltages appearing on U5006 when the Motherboard is supplied with power from a bench power supply for the first 15 seconds or so.
Pin 1 (Trip1) = 0.65
Pin 6 (Trip2) = 0.65
Pin 8 (Vreg3) = 3.31

Good Day to All,
I hope there is someone that can assist me with my GPU. Is does not startup at. Zero fan spin. GPU not heating up at all. I have checked all fuses and voltages that I can find. The one problem (if it is even a problem) is a reading that I am getting off a mosfet. Between Pin 1 of L1014 & Pin 4 of Q4026 ( PS_VDDC_UG5_R) gives me a reading of around 645-650 ohms. Between Pin 1 of L1012, 1013, 1015 and corresponding Pin 4 on Q4020, 4023, 4029 all give a reading of 7.73kohms...Today, 04:17 PM -

hi guys, i have dell inspiron 5570 with a maddeningly slow bios.
specs are: service tag 6MSTDP2 CAL50/DAL10 LA-F115P REV: 1.0(A00) CORE I5 with radeon graphics
When I turn on the computer it takes approximately 5 to 10 minutes to boot Windows, sometimes up to 15 minutes.
That slowness is visible even within the bios menu. It seems as if the clock frequency has been reduced drastically
I already tried some dumps that are in this magnificent forum, I also followed the tutorial by mr [B][URL="https://www.badcaps.net/member/237374-smdflea"]SMDFlea[/URL][/B] to...Today, 03:20 PM -

I have a card that does post at all, the owner said it does go into windows but it gets stuck on the logo with artifacts, I have no idea if he is lying or not... I tried the card on my pc and it does not post at, no beeps, no bios nothing just all fans turning and nothing else. I tried plugging DVI or hdmi but nothing, I tried unplugging the 8 pin plug from the power supply and it's the same thing.
I just want it to post and get into the bios at least.
Forgive me if I am wrong, but I tested the 3 PCIe 12v power pins on the left(550ohm) and the 4th one from the right 3.3v (400ohm),...04-18-2024, 02:42 AM

Hi all,
I'm facing a issue... hope you could help me. I have a T-CON board BN41-02112A from Samsung 55inch Curve TV.
I have just only 2 status blue LEDs ON since LED3 is off. I have tried to test some test points but VON is NOT OK very close to 0V. Is there someone that can help me on the debugging the issue? I'm supplying the board from an external 12V voltage source.
Thank you in advance.
BR,
Michele

Hi community! Germany calling
I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!
I have a KD-65X9005A Sony 4k LED TV.

HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...03-20-2024, 07:29 AM -
