Re: K3405 mosfet pdf

Well, got my caps.
redid psu and mobo.(used gun on mobo, not fun, but no damage.)
fans spin now but no pic and HDD light always on.(had light problem once before on a system.)
- all hardware is good, system ran fine till it just wouldn't turn on anymore.
- voltages look fine.
will take out mobo and triple check for shorts, oh and must do wiggle test first, incase a cap leg didn't get solder right.
(on psu which used normal solder, using the sucker before taking cap out made a nice clean hole.)

added: did try another video card, no go.

removed all caps, checked capacitance with mmeter, replaced all with a nice 55w iron I found(Imperial pencil), still a no go.
- no video & HDD light always on, no floppy activity to do the auto-bios-flash at boot time.(new floppy, tested in this computer.)
- checked for voltage on all caps, seems ok.(just some odd voltages i wasn't ready to see, like: 3.7v, when others do have the 3.33v)
- 2 of the vrm chips have 0v on one leg, 7v on another, but a normal 4.85 on the tab/middle leg.

Looks like I missed the boat on saving this one.(GA-7VT600-L)

Anyone have similar experience with no video and hdd light on, after recap?
(i know i've had that problem before on another board, before I knew about recapping stuff; just don't remember the problem/fix.)

thanks for any feedback.

Re: K3405 mosfet pdf

also, is there a key, for a desktop computer, to hold before power on, to start/force anything?
- just cause some older laptops had that, ibm thinkpad i think.
