Quick diagnostic answers for common issues observed by our technicians in Bilaspur:
Why does the TV have sound but no picture?
Sound with no picture usually indicates that the LED backlight strips or the backlight inverter driver has failed, while the main motherboard and audio processing circuits remain functional. A technician can replace the faulty LED backlight array on-site.
Why is the TV not turning on (no standby light)?
A completely dead TV with no standby indicator light is typically caused by a blown fuse, failed rectifier diodes, or damaged capacitors in the switched-mode power supply (SMPS) board due to power voltage spikes.
Why are there horizontal or vertical lines on the screen?
Screen lines usually stem from loose or corroded LVDS/FPC ribbon cables, or degraded Chip-on-Film (COF) bonding. In severe cases, it can indicate physical panel gate driver failure.
