Hello community
I have a Sharp LC60LE830 TV down.
Symptom:
It does not start, the chevron flashes 1 time.
Pressing the menu button on the remote control gives 1 slow flash followed by a fast one.
It corresponds to an error of lamp or driver led error.
The power supply is a RUNTKA799WJQZ (DPS-183-3A).
Can not start the TV with the remote control or the control panel.
I tried a reset with Chanel - and imputed by reconnecting the mains power.
The relay does not slap and nothing happens.
Measurements on the secondary Pd connector connected to the motherboard
PD connector
(PD-1-2) PNL12V = 0V
(PD-5-6) S13.2 = 0V
(PD-7-8) UR13.2 = 0V
(PD-13) AC-DET = 0V
(PD-14) PS-ON = 0V
(PD-15) BU5V = 5.07V
(PD-16) PNL-POW = 0V
(PD-17) PWM1
(PD-18-20-21) = No connect
(PD-19) Dimmer = 0v
(PD-20) Error = 0V
(PD-23) PWM2 = 0V
(PD-24) STB = 0V
If I unplug the connector of the motherboard and connect BU5V with PS-ON, I hear the relay slammed
At the primary capacity terminal, I go from a voltage of 317 volts to 407 volts.
PD connector
(PD-1-2) PNL12V = 0V
(PD-5-6) S13.2 = 13Volt
(PD-7-8) UR13.2 = 13Volt
(PD-13) AC-DET = 3.3V
(PD-14) PS-ON = 5.07V
(PD-15) BU5V = 5.07V
(PD-16) PNL-POW = 0V
(PD-17) PWM1
(PD-18-20-21) = No connect
(PD-19) Dimmer = 0V
(PD-20) Error = 0V
(PD-23) PWM2 = 0V
(PD-24) STB = 0V
If I connect or disconnect the power of the led ramps changes nothing, I have zero volts on the drivers.
Why the motherboard does not return the wakeful output
PS-On on the power supply?
Whatever the attempts of exit of watches.
Volume - and imput or volume + and channel - there is never a high PS_one command of a short duration.
I do not know what to do to advance my problem.
