    Dead Sharp Aquos LC-32LE430E
    by borstar_micke
    My 12y old daughters tv (that she got after her grandpa, has sentimental value to her) was just dead without stby light a couple of weeks ago.

    Iยดve repaired a couple of computer monitors, classic blown capacitor replacements, a 55" Sammy led with t-connboard replacement and a 42" Panasonic edge led where I replaced the led-strip.

    Not a master with the multimeter, which is cheap and 10-15year old btw...

    So please make it basic...

    To the issue at hand.

    As stated, the tv is totally dead with no standby light....

    Sharp lc32d42u seems dead
    by metropical
    plugged in after being off for quite some time. No OPC lights. Tried flashlight test for backlight check, nada.
    Pulled the PS and checked all diodes including the 5w(?) D7908 that was the issue last time. All diodes check OK in circuit with DVM diode test.
    No caps look unhappy. It is 17 years old. Was gonna fix and give to my brother.
    But is there anything else to try or is it likely met its match.?...

    Sharp LC-40FG2241KF dead
    by Judderman69
    Hello and greetings from the United Kingdom, I'm looking for some help in repairing my grand daughters 'dead' Sharp LC-40FG2241KF smart tv. I have replaced the following damaged parts on the main PCB (TP.MS6486.PB711) :- fuse FB1, switch mode chip UB101, MOSFET QB101,capacitor CB116, resistor RB106, RB148 and a track from UB101 pin 6 to QB102.

    Unfortunately resistors RB105 and RB108 are also open circuit and because of their size (0201) I don't know their value. Could some kind soul please tell me or point me toward a schematic with a parts list, a very big ask but for this I would...

    How can I be sure that my EC chip is dead?
    by double_DD
    Hi all,

    As the title suggests, how can I be sure that my EC chip is really dead?

    I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

    Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...
