When Troubleshooting, Test or Replace the Cheap Parts First

When troubleshooting connected hardware tech, you should test out which component is causing the problem before hastily buying a whole new system. Try replacing parts like the cables before moving on to monitors, receivers, computers, etc. If the problem can be identified as the cable/wires, it will be a relief to your wallet. As a rule of thumb: Start with the cheap stuff, then work your way on up to the more expensive items if necessary.
