All,
Having an issue with the backlight of a family members Television.
TV turns on fine and works fine. Around 2hrs into operation the backlights are shutdown. On the power supply board the LED in the board flashes 4 times. Then repeats.
I have checked all outputs as per service manual and they are spot on. The LED+ GND tes points measures around 76v when operating, but once the backlight drops out it measures 71.3v.
I originally thought it was a dry solder on the power board, but after replacing with a new board its still playing up. Faulty backlight LEDs?
Any ideas?
Thanks.
