The TV shows a distorted picture

Possible causes of a distorted TV picture may include loose cables, incorrect resolution settings, faulty hardware components or signal interference. If the problem is related to the connections, check that all cables are securely connected. If this does not solve the problem, you may need to adjust the resolution settings in the TV menu. Some TVs also have Picture-in-Picture (PIP) or other features that can cause distortion when switched on. If you've already checked the cables and settings, it's possible that one of the internal components is damaged or not working properly. In this case, you may need to contact a specialist for assistance. Finally, signal interference from external sources can also cause a distorted picture. Make sure there are no other devices using the same frequency as the TV and consider moving the TV to an area with fewer electronic devices.

If none of these solutions solves the problem, contact a qualified repair technician who will help you identify and repair all the faulty parts. They can also suggest other solutions if the problem persists. With proper diagnosis and repair, you should soon be able to see a clear picture of your TV again.
