    Zenith SY2768S.

    I replaced the HOT, voltage reg, a switching transistor and a resistor in this
    Zenith television, and it worked beautifully for 3 days.The fuse was also replaced and after 3 days the components which were replaced failed again.
    The tv has been repaired again,but it will only power up if the yoke is unpluged.I have examined and tested the yoke and it appears to be ok.
    Can anyone offer any suggestions?

    MSI MS-16W1 no power, EC replaced by other.
    by MicroSMD Lab
    Hi, I'm working on a MSI laptop, Motherboard number MS-16W11, GF-65 Thin 10SDR-459US. Went to another shop because the screen was flickering, but it was working well on an external monitor. The LCD was ordered and the laptop was returned to the customer and it no longer worked. It was then sent to another tech (by the shop who ordered the LCD) and the EC (ENE KB9028Q) was replaced with a donor from another MSI board with different board number and no programming was done. It looks like work was done on PU6 (TPS51225) as well as one of the GPU mosfets was burnt (I removed all three GPU mosfets)....

    Zenith Z50PJ240 - White Screen with 'Power Only' displayed
    by cmonkey
    Turned on my lovely plasma and after about 30 seconds the screen below showed up. None of the inputs are responsive, just the red light flashes when I push it. Remote doesn't work either. To turn it off I need to unplug it and when I plug it in again it turns back on to this screen.

    I only found one reference to this issue with a different model but it didn't look super reliable. Only mentioned a 'main board fault'. The main board for this one is on ebay for $34 so might need to go with that.

    Anyone seen this before?

    Thinking about it some more, it happened...

    by thesame
    I have a dead FX505D, motherboard FX505DD REV 2.0 , the owner replaced the cmos using a screwdriver and he touched something on the board, since then the laptop its not starting, i have managed to see that U8800 (BQ24780SRUYR) charging IC is getting hot under a thermal camera , i have desoldered it but the laptop still doesn't power on, i also have no voltage at power connector on the board. I also replaced the U8800 but still no power. What should i check next?

    HP Probook 640 G5 - replaced blown components, getting power led, fan full, 5-flashes on CAPS Lock and NUM lock, black screen
    by zlr8r
    Hey guys, bit stumped with this laptop after replacing 2 blown components i.e., MP86493, MP2979A.

    To begin with, this laptop was dead-dead.

    Now with replaced (visibly) blown components, i do get some progress; after connecting battery or main cable;
    • am getting white power led
    • 5-long-flashes on CAPS Lock and NUM lock
    • then, fan full speed
    • CPU heats up some (smaller die PCH, does not)
    • always constant black screen no matter what's tried
    • no USB recognition
    • no HDMI output
    this is as far as I can get with it and not sure where to inspect next ?

    I tried...
