Yeh pretty hard to get that panel off and with minimal components and tracks on it, would have liked to have had access to it initially, my test readings were spurious and so i did'nt think it was there
.
With electo's they can dry out over time especially where they get hot, like in power supplies
I found a computer thrown out, supply was switchmode and protected, would'nt switch on, tested motherboard it was low.
Connected regulated supply to board,at the board voltage, wound up the current till problem, stuffed old electro smoked.
Nothing like cooking a stuffed old component or land bridge short to find it quick, good old trick.
Modern FET'S have the protection diode too, yeh the gate on them seems to take some handling abuse, we use to joke in the when i worked in the industry, 80's, that gremlins caused ic's to fail, static killing components was just a myth.
Especially when we were chained to a test bench with an anti stat strap all day.
