Re: Panasonic TH-42PZ85E --> Completely dead!
Found my PSU. It's definitely not usable as-is, missing lots of parts, but MC701 is untouched.
I had it wrong, this one is one someone before me butchered completely doing the MC201/MC301 repair. I tried, but ultimately failed to repair the damage they had done.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Panasonic TH-42PZ85E --> Completely dead!
Hi Tom , forgot to update this thread! Shame on me , now i cant help other people with this thread.
Got a new PS and the tv turned on. The problem was the CPU on the powersupply.
My girl accedently damaged the screen while cleaning it , it now was a small crack on the screen. The coating layer is damaged and unfortunately this panel does not have a glass front like earlier plasma's.
Will use this tv as a test machine.
So whoever has the same problem , a new PS did it for me.I only repair Panasonic plasma tv's! Currently owning a TX-P55VT50 and still searching for a ZT60!Comment

Re: Panasonic TH-42PZ85E --> Completely dead!
These panels -do- have a front protective glass. However the glass has an antireflective coating and so cannot be replaced with conventional glass.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

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! -
