The apps by themselves crash, the TV reboots or even overheats. You have lines or flicker on your screen. Storage remains full even though you remove apps. The TV refuses system updates. This one indicates faulty memory, a bad main board, bad power--it is not a bug in one single application.

Bring the model number, rendition of software and list of your symptoms. This helps the tech to confirm parts more effectively and pay a visit to the subcontractor without return.
Get fast help with a query such as the TV repair near me. In case it is a broken screen, call an LCD screen repair store. When it comes to problems with apps/boards, request a local TV repair expert who deals with smart TVs and is able to test storage, power, and network modules.
