    Lenovo Legion Y520-15IKBM - No power besides the main rail
    by Fronczek
    Hello people,
    I've got this laptop not working for repairs, and as you can see something was done to it as you can see in the coils PL58XX (which I for some reason cannot find in the schematics...) The first FET (PQ201) was not an original part and a questionable one at that and the second one (PQ202) was shorted. Both are N-channel. Ordered replacements for them and replaced them after arrival. Now I have encountered another problem: there is no power at the second FET. By following the thread linked I got to the injection part. Applied 0.8V at 1.5A, but couldn't feel anything getting hot,...

    LCD Connector identify or source
    by reformatt
    Trying to identify where to source the LCD connectors on the motherboard side for a HP 14-cf2051la. This one came in with liquid damage to the connector and the flex cable. It appeared to clean up ok, however customer says that display blanks out intermittently. It's a 30 pin EDP flat ribbon cable on motherboard side. Believe it to be a HEDWIG-6050A3155301-MB-A01 motherboard.

    I've stolen the connector from another HP motherboard which matches up but it's not the best since it's been kicking around my donor pile for a while. This connector is different to most flip type ones I have...

    Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
    by maneatingmonkey
    [SIZE=14px][FONT=Arial]I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

    There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short

    Control board for treadmill Horizon Omega II
    by bryanX
    Hi guys!

    Firstly, I will apologize if my topic is in the wrong section, please move it if necessary.
    I want to repair one treadmill from the brand Horizon the model is Omega II. Practically, the motor power control board has suffered one damage.One mosfet has blown and I suppose by doing that, the short circuit has damaged a couple of diodes, one zener diode and two transistors. I hope that is all. I will find out when I will put them all back on board. I have dismantled and cleaned the rotor of the DC motor, tested it, and it seems to be working properly. I suppose it was water...

    Hiopos - Cash Touch - Doesn't turn on
    by samstown
    Hello,

    I have this Hiopos Cash system running on android that stopped working without notice. The power supply is ok, there's light on motherboard but when pressing power button it doesn't turn on.
    I've google for schematics but no luck. Motherboard is S2802_V1.3B. I've took some measure and maybe it could be a transistor, the one I am pointing on with the orange arrow on the pics. Does anyone knows this board ?


    Thanks

    Sony KD 49X8307C
    by Donny2derby
    Hi again all. Picked the above model up a couple of days ago. Information was that it just stopped working all of a sudden. Was from a nice house with no kids or pets and no reason to think it's suffered impact damage.

    Working my way through it. I get a flashing silver light on the front which indicates an attempt to start?? Then it turns off and doesn't attempt to reboot.

    Had the back panel off and with the plugs disconnected to the backlights, on the connectors I'm getting 63v DC on CN 6801 and 4.0v DC on all pins on CN 6802. All except the not connected ones I should...
