Hi all,
I while ago somebody donated a Compaq Portable 486. On the first try it turned on and started booting Windows 95. Yay!
But then....
A loud bang and some smoke! And a dead machine...
I took it apart and found out that on the Power supply, a few capacitors had exploded along with a VDR and the fuse.
"No big deal" is what I thought. And it woud have been.
I desoldered all the bad components, looked them up on-line, wrote everything down and cleaned up the PCB.
Since I was quite busy at the time, I stored everything in my collection room until I finally had some spare time to order the parts and
go on with the repair.
But now I've stumbled upon a problem:
I forgot the write down where which capacitor should go
For the major part it is not a problem because I ordered all the parts in exactly the same dimensions as original.
But there are a few capacitors on the secundary side of the board which i'm afraid to mix up.
My question to you guys is:
Does anyone have a schematic diagram or some high-res pictures of this PSU-board?
Or maybe someone can tell me which values should C23, C27, C28, C44, C63 be?
Thanks!
