If you are getting a picture but no sound; or sound but no picture; or a fuzzy picture or sound, recheck cable connections to make sure they are tightened and that wires or connecting pieces are undamaged. Poor picture or sound is typically caused by one of three problems: poor wire connections, signal interference, or TV settings.

Going outside to make sure nothing is interfering with your signal will help with second problem. Of course, if you have underground cables there is not much you can do about making sure they are clear of interference (that’s read, “Your neighbor cut through it while gardening”). If you have a satellite dish, know that excessive rain or snow buildup on dish can cause signal interference. Use caution when checking your dish, especially if it is on your roof or some other hard-to-reach place around your house. The installer should have verified that no trees or other objects would interfere with your signal from satellites, but take a quick look around to see if new foliage is blocking signal. If it is not on your property, do not cut or remove anything without prior permission from property owner.

Finally, adjusting your TV settings can help when you are receiving a clear signal and all connections are fine. Horizontal and vertical settings are adjustments that most often need to be made, but consulting your owner’s manual can give you a better indication of other settings that can be tweaked.

Troubleshooting requires patience, so make some lemonade, roll up your sleeves, and get started. If none of these suggestions work (9 times out of 10 they will), contact your service provider. They may have additional troubleshooting steps or resources they can make available to you to get your cable or satellite TV up and running.

Even these cartridge fuses have 2 types - those with renewable fuse links and those one-time non-renewable types. The only advantage of renewable type - they are more economical because cartridge can be reused. However, more precautions are needed with regards to cleanliness of contacts, securing of cap bolts, and choice of current rating of link.

Whenever a fuse blows, it means there is already a big fault in circuit. Electricians must be especially careful during this time and take necessary precautions. The fuses blow up for safety. Don't cause another blow up!
