Please help me out in finding schematics or boardview diagrams for Lenovo Yoga 7 2-in-1 14IML9 -
Hello Everyone,
I will be really grateful if someone shares schematics and if possible the boardview of the old Asus Nexus 7 (2012) Tablet. The motherboard is ME370T Rev. 2.4. Now I can find schematics for the Rev. 1.0 but I could not find the schematics for the Rev 2.4. I tried to look for similarities in the Rev. 1 but there are somethings missing, plus the board i have has nearly no component names printed on it which as a newbie makes pretty hard for me to locate things. Any assistance will be appreciated. Thank you. -
I have two of these soundbars, both with the exact same issue. The soundbars were hit by lightning and no longer power on. The PSU does not output any voltage on the DC side. When plugged into mains, the DC output is a stone-cold 0.0 volts. The AC side of the PSU seems to be functioning correctly (as far as I can tell). When checking the plugged-in PSU with my thermal camera, the OB5269CP PWM controller (U1) and the two resistors (R12 and R13) pulse on and off. These run to the positive DC side of the bridge rectifier (among other components along the way).
There's no physical damage... -
I have this Lenovo Slim 7 16IAH7 notebook that is not booting properly. All voltages are there: 5v, 3.3v, 1.8v but it's still a no-go.
I spotted this IC chip with markings "6611c" on it. The coil near this chip measures around 200 Ohms which I think is too low. But without the schematics, it's just a guess.
I wonder if someone has the schematics for this board or perhaps, can help me identify this particular ship. Thanks.... -
I'm trying to explore on fixing things like this GPU I have, it got two resistors missing when I received It. Its for an old PC the seller even told me its r5 240 and seemed its even flashed to show its r5 240 but the PCB says 109-C55357-00_02 V309 OUGA11 please can I get its schematics and Bios Flash? It has 1GB DDR3 memory, and I believe it is based on AMD Oland XT/Pro (HD 8490). thanks in advance!...08-07-2025, 07:51 PM
