blue LEDs @ ~10k hours on LG 49UJ6500-UB and 75UM8070PUA

03-23-2023, 09:45 PM

Recently fixed a couple of LGs with blue backlight (yellow phosphor worn) by replacing LED backlight

2017 49UJ6500 with 10.5k hours (all LEDs turned blue)
2019 75UM8070PUA with 12k hours (>75% of LEDs turned blue)

So the 2019 was averaging 8hr/+day and 2017 probably 5hr+/day

Just some stats for future repairs.
