            TV is back running again I ended up using that bridge as I realised it was only a higher rated one and manufacturers use the lowest they can to keep costs down.

                SYMSI70 gas heater, TOP247Y exploded, power supply, snubber network
                by hikomalek
                Hello, I have a SYMSI70 gas heater board, which has issues with its primary side power supply, controlled by TOP247Y chip.
                When I replace a TOP247Y it explode in 1 second. I have desoldered transformer and measured a winding ratio, so transformer looks like OK.

                Transformer:

                |Info| Primary | Aux | AB | CD|
                |-|----------|----------|-|-|
                |Ratio|1|25|40|12|
                |Voltage AC|230V|9.2V|5.8V|19V|
                |Voltage DC (*1.41)|230V|13V|8.1V|27V|

                I have disabled a undervoltage protection of TOP247Y, disconnected secondaries and tried to power it up...

                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.

                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.

                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...

                MSI B250 Gaming M3 Short circuit in CPU power supply circuit
                by M1NEBLANK SHOW
                Hello. MSI B250 Gaming M3 board, short-circuit on the power supply. Found a problematic mosfet VQ1
                (N-PK616BA_PDFN8-HF) soldered it out - short circuit is gone. I replaced VQ1 + VQ5 (N-PK632BA_PDFN8-HF). VQ1 was replaced with PK618. After starting attempt VQ1 is lit again. What can be the problem? In the driver?
