    QN750Q8FNBFXZA Service Error Codes Needed - Error code 1-3-1-2 ? Dead set, only blinking standby light in repeating sequence
    by mecha1166
    I am working on a QN750Q8FNBFXZA. Dead except the standby light. It blinks what appears to be 1 3 1 2. 1 long blink, pause, 3 short, pause, 1 long, pause, 2 short, pause, repeat. A service manual would be very helpful, or if anyone knows these error codes. Thanks!

    Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
    by Asraf Atb
    Hi everyone,

    Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

    Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

    I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

    Help needed to revive dead HP AC adapter
    by mikey5791
    Hi all,
    Got this HP AC adapter model HSTNN-CA15(output 19.5V, 3.33A) for HP laptop which suddenly died yesterday.
    Opened the adapter casing and did not find any burning part, loose or broken wire but the square T3.15A fuse still has continuity.

    I pulled out the biggest green resistor nearest to main cap at CX2. The resistor has 5 band which is red,red,gray,gold,white. Is this a 22.8 ohm 0.5w type resistor(lenght abt 1 cm)? Please correct me if i m wrong. It measured about 0.4 ohm on dmm, so it is bad. I have no exact replacement so i use a 30 ohm 2w from my stock but...

    How can I be sure that my EC chip is dead?
    by double_DD
    Hi all,

    As the title suggests, how can I be sure that my EC chip is really dead?

    I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

    Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

    Help needed to revive dead Asus EXA082XA AC adapter
    by mikey5791
    Hi all,
    This model EXA082XA Asus ac adapter just died.
    Opening the case, there is no burn mark or any damage component. Glass fuse still has continuity. Diodes and 2 transistor has not shorted. I just suspect a 8 pin ic label Chip Rail CR-LSN69 but unable to get any datasheet.
    Does anyone know how to test this ic or any equivalent substitute such as TOP258PN can be used?

    Any kind assistance and guidance is highly appreciated. Thank you....
