    LG Plasma ZSUS Flashing Screen, No Booting! - 50PB690V
    by reessi
    Replaced Zsus beginning of year as most transistors were short stopping tv powering up.

    Now screen flashes on off continually and ZSUS ticks. Looking like replacement maybe faulty or could something else cause it to shut down.

    If I remove both tabs from ZSUS to screen but keep all other connectors to ZSUS on then TV boots properly but screen very dark without ZSUS output, no ticking from ZSUS. So it only shuts down when under load from screen.

    If it is ZSUS then how to fault find, I already looked for shorts. No transistors shorted or caps and its...

    Lenovo YOGA 2 13 (20344) hot cpu when plugging
    by Garibean
    Hi

    I'm a beginner in laptop repair, a friend of mine gave me his laptop to repair, a Lenovo Yoga 2 13 (20344), he said that when he plug the laptop, he hears a buzzing noise.
    I checked, this is a coil next to the cpu. When plugging the laptop, the cpu start getting hot and the coil next to it too and that without even touching the power button.
    My guess is that the cpu is simply fried and he can now toss it in the bin.
    (I also could not find schematic for this laptop so i will create a thread about it)

    Do you have any idea about what it can...

    Hi,

    Try to repair a Thinkpad P72 EP720 NM-B723 MB with I7-8850H processor and N18E-Q1-KB-A1 (P3200) GPU with 6GB memory. Unfortunately there is noinfo what happened to the laptop. I got it disassembled with parts missing, like keyboard, battery.

    Unfortunately I have no schematic available for me (requested in the sub porum) but got the boardview file.

    Symptom: after connecting to the charger the power led light up for one-two second and switch off. After a couple secons the power led light up for half a second and switch off. No battery, no IO board, no...
