Hi.
I have a damaged Toshiba notebook that doesn't turn on.
Checked the board for burnned marks. Found nothing, measured resistors, diodes, capacitors arround the PSU area, all fine.
If i turn the board on without the CPU it works and gives a led error stating missing CPU, found the led codes somewhere on the internet.
The only marks I see are on the transistors around the bottom part of the CPU, it appears to be a discoloration on the transistors.
The same transistros brand new are black glossy, these are really black, some of then are half back and half glossy, some are grey.
This discoloration tells me overheating and maybe they are damaged.
They are Toshiba transistors made by Toshiba for Toshiba notebooks.
I have the Datasheet for them.
Also they are quite cheap but I would like more opinions before I replaced them, not for the money, but for the trouble and time i'l waste.
Please look at the photos and give opinion.
Thanks
