🔍 Identifying Your TV’s Symptoms
Before diving into repairs, it’s important to correctly diagnose what’s wrong. Here’s a quick checklist:
-
Display Issues: Pixelation, discoloration, or flickering? These could be caused by a faulty screen, T-Con board, or LED driver.
-
Sound Problems: Muffled audio or delay? Check your audio settings, speakers, or external sound systems.
-
Connectivity Glitches: Can’t connect to Wi-Fi or HDMI not working? It could be software-related or a hardware issue.
-
Power Trouble: No power at all? Time to inspect cords, outlets, or the power supply board.
-
Remote Unresponsive: A simple battery change or re-syncing may solve the problem.
