    Sinotec plasma -please help identify

    Hi Guys,

    Could some one please help me identify either the model of this set or the 8 pin dil ic in the start circuit. (I think its the start circuit).

    The set belongs to a friend who took it to another repair company who kept the set for over two months, with out contacting him. (poor service).

    Who ever looked at it appears to have put the wrong ic in the start circuit.
    The ic that had been fitted was an LNK364PN. The specs' show it to have pins 1,2 & 7,8 common and being the source of the mosfet inside. However the print on the board suggests otherwise. see photo .

    I tried electrotanya with all the numbers on the psu pcb, no luck.
    the label on the back cover says the set was manufactured in 2004, but no model number.

    The slightly swollen cap next to the chip lead me to the fault area, then I saw the burn mark, & the previous repairers work. see photo's

    The only components that appeared to have been soldered on/replaced were the ic & transformer (see photo). Strange that the cap is only rated at 85 degrees.

    Hoping that someone can help?

      Thanks Dick, will try source one, I don't like repairing plasmas, but it's for a friend. I find it difficult getting spares in from local suppliers, & dont really want to buy online, so will be scratching in my salvaged stock.

            Help me identify the missing component... Sound to light circuit
            by edugimeno
            hI there!
            Im trying to help a friend repairing a large, real-sized short-circuit robot.
            This is remotely controlled and has a 2 way voice send/receive. Also while the hidden operator is talking, the red bulb inside the "mouth" should flash according to the sound
            Some other technician used to service it and he was fired leaving all the repairs unfinished and no documentation at all.

            What I found is a sound receiver, a speaker, and a wire directly to the mought bulb (a normal motorbike 5W 12V bulb).
            So I bought a simple 2X30W amplifier to feed the loudspeaker...

            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.

            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?

            Viper22A 5VSB circuit
            by прямо
            So I have a cheap non working ATX PSU that I was learning to repair a decade ago. At the time, it blew the main fuse, bridger rectifier, NTC, and primary 9A 900V MOSFET. Replaced all except the MOSFET. 5VSB came back online. Then I poked around in it so much, measuring components one by one to a point I accidentally made the 5VSB circuit primary side went bang. Blown the AP8022 (Viper22A) PWM chip, along with a low resistance resistor and the PC817 opto isolator. I replaced them all.

            In the process of poking around, I also lost a zener diode that stabilize the voltage coming from...
