My PC didn’t boot. I thought the logic board (Mather board) was damaged, maybe it is the condensers. I’ve replaced the logic board with another one, now my PC is working again.

This repair has become a practice to compose my PC with parts I trust and select.

And I replaced my iPhone’s battery, achieved. But this work is very risky, the iPhone will be lost forever with a single smallest mistake.

I repaired also DVD player and CD player. These are working now very well.

And …

… I bought condensers for the mother board (logic board), about $18, but …

… the melting point may be higher than my soldering iron’s heat.

I couldn’t replace the condensers.

If my PC’s mother board breaks down, I’ll buy another mother board into which Windows 11 can be installed. I’m using two PCs, Linux and Windows.

I bought a second-hand PSP. Its work made a noise. I used a chain lube, it’s semi-dry type and not contained abrasive.

To a gear of the optical drive. When I sprayed the chain lubricant, I covered PSP’s optical lens with a lens cleaning cloth for camera. I sprayed very small amount, and waited the permeation to deep placed parts for 10 times reboots.
The PSP is working quietly now.

All above is self-help with my own responsibility.
