There’s nothing more frustrating than sitting at home trying to watch television when the image is blurry and keeps cutting out. Calling the experts isn’t always convenient, especially if you’re in a hurry to get your signal back. Luckily, not all issues require the attention of a specialist. In fact, you can probably fix the majority of problems yourself. The steps, however, may vary depending on your setup and whether or not you can troubleshoot the problem.
When experiencing a loss of Digital Freeview signal, turn off the device and check that all of the leads are secure. If everything is okay, turn it back on; but turn off any other nearby electrical devices, such as lamps. Your system could be subject to an electrical interference.
If you’re screen is covered by a solid block of green or a rainbow-like formation, you probably have a loose or faulty SCART cable. Simply reconnect or replace the cable and retune your television. If, however, you encounter regular signal errors you should consult a professional. They will be able to determine where the transmitter is located, and re-align your aerial using the right equipment and safety precautions.
It’s easier than you think for a satellite dish to get knocked out of position. If this occurs then your dish could be facing an obstruction – usually a building or tree – and not getting the optimum level of signal. Firstly, try retuning your television. If this doesn’t solve the problem then you’ll have to get an engineer to realign your dish.
Unfortunately, satellites and heavy rain do not mix as the signal could struggle to get through all of the water obstructions. This can significantly decrease the signal power and could cause your television to cut out altogether. If the problem occurs every time it rains, then you may need to move the entire dish to a more weather-proof area.
The problem with digital cables is that when glitches occur they can be very difficult to pinpoint. The cabling is often the last place that’ll be thoroughly assessed, but can cause symptoms similar to misalignment.
If all of your cables are secure and well connected, check your splitter (if you have one) by removing it and directly attaching your satellite cable to a television. If you receive the right amount of signal, then you’ll probably need to replace your splitter. As with any setup, cables can suffer from weathering and slowly deteriorate. When this occurs they will need to be changed immediately.
Dysfunctional signal and blurry picture quality is a common problem. If you still encounter issues after making these quick fixes, you might need to change a major component, such as the satellite or Freeview box. Never attempt to undertake any dangerous re-installation procedures yourself; you should always call an expert. Without the proper training and equipment, repairing a television setup can be a very hazardous.
