        That model number is a PLASMA TV. Check your model again.

            Asus X453MA won't turn on and green led light blinking
            by jxrepman
            Hi there,

            I have this ASUS X453MA Laptop that's not turning on. When I plug in the charger, the green light just keeps on blinking and pressing the power button does nothing.

            I have checked the charger and it is giving 19+ V

            I have disconnected the battery and pressed power button for 30 seconds.

            I tried another RAM stick.

            Tried disconnecting the keyboard and touchpad.

            Tried disconnecting the HDD and the wifi adapter.

            The problem persists.

            Hope you could help me out on this one. Thank you.

            HP ZBook 17 G3 Mobile Workstation LA-C391p won't turn on and the power light is blinking
            by my dodge
            Hello
            I was looking for a schematic or board view but unfortunately I didn't find anything.
            By connecting the drain and source of pq58, the device turns on and works perfectly, but the battery doesn't charge, and I don't know the path of the circuit to the MOSFET.
            Is the problem with the adapter? Or is there a problem with the MOSFET activation circuit?
            Please guide me.
            Thank you.​

            Samsung UE40F5300AK blinking red light
            by Fergal22
            Hi,
            I have the above tv that just shows a red light blinking twice 5 times, i have taken the back off and all the capacitors seem ok,
            When i disconnect the mainboard from the PSU all the led's light up blinking fast but as soon as i reconnect the mainboard back to the power supply i get the red light blinking again twice 5 times,
            I have attached pictures of the Mainboard, PSU and a small video (zipped) showing what happens when i disconnect the lead from the psu
            Any help would be appreciated...

            by Adogabriel100
            Hey! how are you guys? i wonder if you could help me with this macbook 820-2936 that does not turn on. (Doesn't have green/orange light).

            History:
            this macbook came for a short on C6990 that blows D6990 and R6990 on his way. i re-placed the componets and it work again.

            A month later comes back again and has the actual problem (no green/orange light and dont turn on)

            The macbook can turn on with only the battery connected but in fact, dosent charge.

            Voltajes:

            PP3V42_G3H = 3.3v
            PPBUS_G3H = 12.2V
