A repeat pattern of 6 red light blinks indicates an over-current trip on the backlight inverter driver or an open circuit in the LED array. We install balanced LED string sets with original Sony heat sink mounts.
Five red flashes indicate an I2C communication handshake timeout between the main motherboard and the Timing Controller (T-Con) board. We repair T-Con power rails and level shifter ICs.
Four blinks point to an over-voltage or under-voltage condition on the main G-board power supply module. We replace standby voltage regulators and optocouplers on-site.
Bravia models experiencing vertical jumping or double ghosting images are repaired using precision clock line isolation on right or left COF channels, bypassing defective gate drivers without panel replacement.
If your Bravia XR gets stuck on the pulsating Google animation or fails to launch the home launcher, we perform eMMC chip reprogramming and update system software via service port tools.
For OLED Bravia TVs with screen-vibrating Acoustic Surface Audio actuators, our engineers repair vibration transducers and multi-channel Class-D audio amplifier circuits.
