    Re: LG 42PT350R clicking problem fixed but still doesn't turn on

    When I plugged everything together and turned the tv on, I heared a buzzing noise out of Z-SUS and Y-SUS boards.

    Once I heared that buzzing sound out of one of the IGBTs or transistors on the z-sus and then I found out that a couple of them were shorted.

    yesterday, before I plugged everything in, I checked for shorts and there weren't any shorts but I heared the buzzing sound.

        LG 60PV450 Possible Bad YSUS Need help confirming Diagnosis
        by PlasMatt
        I have an LG plasma that after reading through a bunch of posts and doing some testing I believe has a bad YSUS board. The problem is that that doesn't make sense to me for some of the symptoms. The problem started yesterday. While watching a movie the TV just shut down like I pressed power. I have it hooked to a PC and use RS232 to turn it off and on so I thought maybe something had glitched there. I turned it back on and finished the movie with no problems. The same thing happened today so I checked logs to see if something in the control glitched and sent an off command but it didn't, After...

        Samsung UE49KS7000SXXH - fast clicking sound in standby mode
        by B0r1s
        PSU - BN44-00878A

        Symptoms:

        The TV turned itself off, and I haven't been able to turn it back on. The standby voltage was unstable and lower than it should be.
        A weak clicking sound was coming from the transformer.

        Video with clicking sound:https://www.youtube.com/watch?v=lAduhjNtqCA

        Progress:

        After the transformer, I measured four Schottky diodes. DM862C and DM864C diodes readings were 003 in both directions. After detaching them from the circuit and measuring them, DM864C was the shorted one. These Schottky diodes are SB550.I...

        LG 42PC3 buffer output doesn't follow YSUS
        by legg
        LG42PC3D -UD originally with green lamp but no display or audio.
        Owner says was working, then went 'pop'.
        All 5V caps bulging. replaced.
        All PSU output voltages within spec but -Vy is low on YSUS.
        One of three parallel fets between SUS_OUT and SUS_DN is zenering,
        eventually shorts DG. Replaced all 3 - -Vy now OK.

        Y scan buffer test point does not follow YSUS output below -50V

        Note: This unit seems to expect YSUS output to park at -Vy in between
        drive signal pattern periods. A replacement drive signal board confirms this....

        Samsung UN55NU7300F Curved TV. Half side backlight out. Fixed by just removing the rear snap cover
        by howardc64
        TV was fixed just after removing Samsung's rear snap cover.

        This curved TV's construction is rather interesting. When the snapped on back is removed, rest of the TV will relax the curvature. Top of LCD panel is loose as it wants to straighten out against the slightly curved bezel. Snapped back provide most of the curvature shape. So just simple disassembly of rear cover will allow the rest of the TV frame to relax its curvature. Thats probably what fixed it but no idea which connection. 4x LEDs are edge lit.

        Maybe PSU->backlight connector didn't have a good contact?...

        [SOLVED] M1 MacBook Pro clicking sound logic board 5V no power on A2338 820-02020
        by slimmy182
        Hello, I bought this Mac from a friend, he said that it simply stop working. The MacBook looks very clean but does not power on, stuck on 5v 0.42A, and sometimes display 5V and 0A (then 0.071A and again 0A).

        I opened it looking for some problem, it was not touched before for sure and the board is very clena, no spot of corrosion at all from what I can see. Voltage on multimeter of the board off the case it's the same, 5V 0.42A. But then I noticed this "clicking sound" come from the board ( I attached here the audio file).

        Looking on google I found this:...
