        help SG2701B01-7 panel chinese, would this integrated circuit be equivalent? Chinese IC CS601C regulator.
        by valente222
        Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...

        op amp circuit function?
        by Alimash
        Hi,
        I am repairing a ups which doesn't turn on ,it has the following ICs:
        SG3525 used to drive inverter mosfets.
        couple of uc3483, one for the power supply and another to drive a big mosfet at the output stage(i think the technique is called boost)
        A LM358 and TL074 for control mechanism and of course the uController.

        The SG3525 is shutting down every time the ups is turned on.
        I want your help to know the function of LM358 and TL074 in the system.
        I reverse engineered the LM358 circuit and i think that one of the block(A) is used for battery level...

        Fixing the Charge Circuit of the Batteries of the DC Motor
        by Astonished
        Hi friends of electronics

        What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.

        The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.

        Please help me fix this circuit.

        Lenovo L490 Ram voltage circuit malfunction
        by rddube
        Hello friends,

        Looking for some guidance here. The RAM voltage circuit on this motherboard keeps burning out PU301 which is a RT8231AGQW. Copy of the board with the burnt chip attached with some voltage measurements and copy of the schematics also included.

        I think I've checked almost every component in the circuit, but when I change the RT8231, the laptop starts I have 1.2V on the inductor for about 10 seconds and then the RT8231 goes south and no more voltage on the inductor. All other voltages on the laptop are good, this is the only one conking out for a reason I...

        Short Circuit tester
        by Tarot Superstars
        Hello.
        I have seen a short circuit tester made with 3 * 9V batteries, a voltage limiter component and a resistor connected to the probes of a multimeter.
        The theory is that the meter becomes sensitive enough to read very low resistances and the lowest resistance to ground on a circuit is likely to be a short circuit in that area.
