160: Old Computer Diagnostics. Is it really worth fixing?
Channel: The Tech Doctor Network
Date: 23/05/2021

In this episode, we look through some possible causes of a dead computer starting with an old HP Desktop that on closer inspection had a burnt-out pin between the Power Supply Unit (PSU) and the auxiliary power connector on the motherboard. Rather than dig any further on a machine that was clearly past it, I made the decision to pull the plug, back up the data and send the machine to e-waste.

Other similar issues shown include a burnt-out 24 pin motherboard connector, Capacitors that have spewed out their electrolytic insides (or almost have), scorched resistors, burnt chips and cabling and even graphics cards.

Most of these are not worth fixing, but individual components can after be replaced if the overall system is worth keeping.

The exception might be systems that really expensive and often built for purpose, or something with some sort of sentimental attachment, like my CoCo: 083 Tandy Color Computer (CoCo) from 1980: A trip down memory lane back to where it all started: https://youtu.be/nPqgAEpKzro

Stay tuned for an upcoming episode all about e-waste.
