Default LG 55UN6955ZUF. Help

Hi
I recently acquired an LG55 UN6955ZUF
When I cycle it on it has backlights and audio.
No video just the light blue hue of the backlights.
Iíve replaced the main board hoping it would take care of the problem but, same outcome.
Iíve started taking some reading from the buffer strips on the panel itself but Iím not sure what the reading should be.
Hereís the current readings

LEFT SIDE BUFFER
VCC33. 3.35 VDC
CLK 70 ohms
DI 130 ohms
GND. gnd
CS 3.27 VDC
DO. open
WP. OPEN

RIGHT SIDE BUFFER
VCC33. Open
SCL. Open
SDA open
GND GND

Has anyone had issues like this.
The tv is only around 4 months old

Thanks in advance
