    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,...

    Sony LED 65X9005A shuts down after few seconds - looking for help
    by tec3000
    Hi community! Germany calling I am wondering if you guys can help me out. I have an issue with my Sony LED TV. I've been told this is a good place to ask. Thanks for anyone who will reply and offer advice. Appreciated!

    I have a KD-65X9005A Sony 4k LED TV. For a few weeks I've got this problem where I turn on the TV and within a few seconds the TV starts getting darker until it shuts itself off and I get the 4 blinking error code. HOWEVER there is one exception: Whenever I switch to the i-Manual, a full screen on-screen instruction manual, the TV never turns off. I tested for hours!...

    Dell Inspiron 5570 and burnt parts
    by padluke
    Hello, I would like to ask if there is anyone here who could advise me if it makes sense to repair a motherboard damaged in this way. The damage occurred when the ntb was not turned off in the bag, where it got too hot. After cooling down, it wouldn't start. After removing the motherboard and connecting the adapter, the PQA01, PUI02 component burned, which is shown in the attached picture. PUA01 and PUV01 is very hot right now. Thanks a lot for any advice :-)

    desoldered capacitor is self charging until 0.6 voltage.
    by chth96
    I have an 21 inch CRT TV which is not able to power on.
    I disassembled 21 inch CRT TV and measured voltage of main filter capacitor(Samhwa HC 400WV 220uF) in the circuit.
    It shows 270V on my DMM.

    So I discharged this main filter capactior completely and detached circuit board from cathode-ray tube.
    Then I desoldered this main filter capacitor from circuit board.
    But I noticed that this desoldered large capacitor(Samhwa HC 400WV 220uF) is slowly charged by itself until it reached 0.6V

    I measured its ESR value with MESR-100 and it shows 0.1 ohm,judging...
