TV has sound but no picture
Fix a TV with audio but a black screen: run the menu and flashlight tests to tell a failed backlight from a bad input, then check HDMI cables, ports, power resets, and picture settings.
Netflix NW-2-5
NW-2-5 means your device took too long to connect to Netflix, which Netflix attributes to the internet connection on the device or the home network rather than to your account or the app.
Canon error B200
Canon publishes two different answers for B200. On printers with two cartridges the print head is inside the cartridge and replacing them can fix it; on printers with individual ink tanks, Canon says the printer requires service.
AirPods not connecting
Fix AirPods that won’t connect: the Bluetooth list splits the fault in two — missing entirely means pairing mode, listed as Not Connected means a stale pairing or another device holding them. Includes model-specific pairing and reset steps.
