HP38E repair, any advice welcome !

[albertofenini]

Hi everyone,

we tried to proceed in replacing the damaged flat cable with a series of thin wires.
We followed the scheme we posted yesterday, and after a couple of tries we were able to bring this
HP38E back to life.
The first attempt failed because there not an exact correspondence between the "pinout" of the PSU
and the "pinout" of the motherboard.
In fact the first pin left of the PSU just bring the charger cable to the PSU and is not connected to the motherboard, as the pin number 5 from left.
This we failed twice because we were fooled from the fact that this pin has a trace on the motherboard
but no correspondence on the PSU so we soldered all of the following with an offset of 1.
That's why you will see in the picture a green wire connected to the motherboard and floating free.
We removed this at the end.
Chassis has been cleaned and it is in good shape although it shows some wear around the keys where the metallic face plate has worn off a little.
We will probably cut the flat ribbon cable as no longer necessary, in the pictures is still attached.
As always, any comment is more than welcome !
Take care !!
