Friends,
It appears I've accidentally applied 19VDC to a PCB that should only run 12VDC.
The board now does not power on, even with 12VDC..
Using a thermal camera shows entire board remains COLD except one component (near power plug) that heats to 120C and higher!!
Suspected component is marked with "T" (slanted) and "BE", think/hope it is some kind of fuse, in photo just ABOVE the green power terminals and LEFT of the 16V capacitor (on right of photo)
Interesting part is measuring continuity across that component shows 0-reistance...

Hi,
I have a Dell Inspiron P157G004 here which does everything except turn on the screen. I see a lot of activity on the bios chip's pin 5 but just a high signal on pin 2. Therefore I suspect the content of the chip.
Could somebody take a look at the attached dump?
The info from the sticker:
Reg Model: P157G
Reg Type No.: P157G004
ZU10247-21009
R-R-E2K-P157G004
DP/N: CC6TY A00
ST: JF64DS3
EX: 42276139203
Thanks in advance... -
