Probably LED string issue but wanted to check any more easy testing before ordering the LED strips.
Inspection/Probing
Disconnected PWM_BLU between main and PSU
LED Tester
Anything else to check before ordering LED strips?
All pics shown are with PWM_BLU disconnected
Inspection/Probing
- No shorts around caps on main
- No bulging caps on PSU, no evidence of any damage
Disconnected PWM_BLU between main and PSU
- Backlight powers on when PSU gets power. Doesn't wait for main board power on.
- Remote turn on TV, display is perfect. White screen test shows no dark spots
- Remote turn off TV, backlight stays on until PSU power pulled
- Both LED strings reads 124+V. 14x 3v LED / strip x 3 strips for each string
- PWM_BLU line on PSU reads 3.1v
LED Tester
- LED strings disconnected from PSU. Tester only drive up to 109v. One string ramps up to 109 a little slower when powered off for awhile.
