Re: LG 50PB560B completely dead
I'd suggest using the thread you created as your TV is 1080p and this is 720p.
It's a similar layout to this TV however there are many differences.
It's confusing for other folk looking in.
Anyway I've asked you a question in your other thread.Comment

Re: LG 50PB560B completely dead
Thanks a lot for your support.
z-bias = 66-67V
vy = 0, cant find test point for vsc on Y-sus board.
I'm just not sure if there is a problem with Y-sus or Z-sus.
With disconnected Y-sus or both (Y-sus and Z-sus) still no signs of life, no standby, no reaction on remote etc...Comment

Hi, I disassemble my laptop to replace the speakers, to access them, you have to remove everything including the heat sink and fan, unscrew the motherboard, lift it up a bit to access the speaker wire.
that was not the first time I dissasemble it, i did replace the same speaker a few year ago and I repaste it last year, so I had nothing to worry about. but when I put everything back together, its completely dead.
After a bit of investigating, i found one pin of the status led ribbon cable that was unglued from the cable and bend touching another pin, I bend it back at his place... -
Hello Gurus,
I got a ThinkPad T480s. It was running fine but suddenly started random shut down. When it turned off, I had to push the reset pin to bring it back to life. But it got aggressively worse and became completely dead. No charging light, no life.
I did some initial diagnostics with just the board (no battery, nothing attached, and no CMOS battery as well)
Initial testing of the coil resistance seems to indicate no dead short. The only low resistance I measured was at PL701. It reads 38 ohms.
charger gave - 20V - ok

Trying to troubleshoot MSI z490 tomahawk board and would appreciate your help. The board is completely dead and shows no activity when the power button is pressed.
I have tried to look at the Superio, the PSIN signal seems to be correct (goes from 3.3V to 0 on button press) but the voltage on PSOUT pin is quite low. I
t is only 0.8V which seems to be incorrect but goes to 0 when the button is pressed.
Can you please let me know if this is indeed incorrect and what else should I look at next?
Thanks! -
Hello.
I received a T14s Gen1 ( NM-C891 motherboard ) that is completely dead, no indication of life at all.
I tried hard reset without RTC battery and short both pins of it for 1 minute but no luck.
Since it's type C connector i have no idea what to measure or where to inject voltage, so any advice are welcomed
Thank you in advance!

Hi everyone!
Three years ago I got a ZD-915 desoldering station which failed just after a few months of light use. During a short desoldering session, the station simply shut down, and since then it has been completely dead and unresponsive. The failure was silent, without any pops.
Due to a lack of time, I set it aside and didn't look at it.
Yesterday, I took it apart and did some basic measurements. The 18v terminal shows 0v. In addition, there is no visible damage to the board itself.
According to replies in 18VDC PSU has dropped to...
