    MOSFET no voltage at gate Quanta G7HA DAG7HAMB8EO
    by irfan karatela
    I'm working on a HP Pavilion Laptop Model 15-eh1508sa that is missing 19v. I've looked at the schematics and want to know what conditions the ISL9238C checks before it enables the gate for MOSFETs PQ8200 and PQ8201,

    I havent found any shorts on the board.

    I get 19v at +PRWSRC but around 1.7v at the Drain of PQ8201(+vin)

    NV-V8000 vcr caps change
    by Thermaltake
    Hi, I am restoring my NV-V8000, and wondering there is 16V 4700uF cap near transformer, is it low esr one or normal one ? On PSU they are all replaced with low esr, but I am not sure about that one near transformer. I tried to google and look at manual but I couldn't find anything.

    Yamaha RX-V677 Not turning on
    by afnan
    Hi,
    My RX-V677 decided to quit on me.The standby light is not there and when i turn it on it just blinks. I have checked the error codes and there is one `PS3 PRT:127 L` Looks like its a power supply issue. Checked the manual and normal values are
    Normal value PS3: 132 to 168 and it monitors 5.5V

    LG OLED55CX Clicking No Power
    by cheebster
    Hello, i have this OLED here, as the topic says OLED65CX.

    TV shows standby led, when pressed the PSU clicks, then shut down.

    Disconnecting the 12V VIN from the T-Con, make the TV boot up, led flashes like normal and it stays on.

    What i've tried so far:

    I have a working TV, an OLED55C1. Similar TV... Took all the boards to the C1, 1 by one, and everything works. So basically, all of these boards from the defective CX (PSU, Main, TCON) works either 1 by 1, or together on the working C1.

    However, none of the C1 boards work on the CX,...

    AMD RX 6800 XT no GFX and SOC voltage
    by DexMexDC
    Hello, I have one AMD RX 6800 XT and one RX 6700 XT with very similar problem. Both have no GFX and SOC voltage. But lets start with the 6800.

    I have experience in electrical engineering and measuring instruments such as multimeters, oscilloscopes, laboratory power supplies, thermal imaging cameras but I just can't get anywhere here.

    Let's start with the 6800 XT:
    - no visible damage
    - No short circuits
    - VMEM - 1.35V
    - VMEM Controller - 0.89V
    - 5V0 - 5.02V
    - 0V75 - 0.74V
    - 3V3 - 3.27V
    - 1V8 - 1.80V
    - VDDCR GFX - 0.0V...

    Galax 3090 bad duty cycle on mem phase
    by pedrolopesbe
    I got this 3090 wich I own, same board as the common 388_50 boardview.
    I'm new to SMD work, and in a moment of stress trying to solder a 0402 filter cap that I've knocked out I've made a big solder mess in the "U42" drmos.
    As past is past, after getting a pre heater now I succesfully unsoldered the chip but I'm having problems soldering it back again.
    At the last time I've worked on it, I had to reflow it as it was not giving any out signal, measuring using the Hz function in my multimeter.
    Now I get a reading of something like 1.7kz while other phases 3.09khz...
