Re: Sharp LC-60LE600U turns off after turning on
So most likely there is a failure on that LED strip? Does it sound like the power board is alright?

It ramps up to 3.29V then stays steady until the backlight flashes on and then the tv turns off.Leave a comment:

Re: Sharp LC-60LE600U turns off after turning on
I'm not sure of the history before I got it so I don't know if it was hooked up to a surge protector. I had this plugged into the outlet directly before adding the surge as a means to turn if off and on easily. It's doing the same thing the people I got it from were reporting that it would light up and turn back off.Leave a comment:

Re: Sharp LC-60LE600U turns off after turning on
I must have not made good contact on some of the readings. I was backprobing the female connector.
1) PD24 STB hits 3.06V then the backlight flashes on for a second.
2) I have the LED pinout backwards Should be:
L1-15 LED4- 11V 0V
L1-13 LED4+ 83V 0V
L1-11 LED3- 11V 0V
L1-9 LED3+ 83V 0V
L1-7 LED2- 11V 0V
L1-5 LED2+ 76V 0V
L1-3 LED1- 11V 0V
L1-1 LED1+ 83V 0V
3) None of the LED+ read over 83V
4) PD16 PNL_POW jumps up to 3.26V...Last edited by mikeroq; 09-18-2019, 08:12 AM.Leave a comment:

Re: Sharp LC-60LE600U turns off after turning on
I tried with the cable unplugged from the main board. I don't think anything turned on the only voltage I saw was 5V on the BU5V. Do I need to jumper the power board on?
All I know is that it was working normally until it started doing this.Leave a comment:

Sharp LC-60LE600U turns off after turning on
I have a Sharp LC-60LE600U TV. So far I haven't found a service manual for it.
The LED indicator will light up white and then turn off after about 10 seconds.
I noticed when probing the voltages right before the indicator would go off there would be a short buzz and I could see the LEDs light up for a second at the edge of the panel.
PIN VOLTAGE ON VOLTAGE AFTER LED TURNS OFF
PD1 – PNL12V 12V 0V
PD2 – PNL12V 12V 0V
PD3 – GND 0V 0V
PD4 – GND 0V 0V
PD5 – UR13.2V 0V 0V
PD6 - UR13.2V 13.2V 0V
PD7...Last edited by mikeroq; 09-17-2019, 02:59 PM. -

Hi. I signed up years ago but never went any further. Pretty much forgot about this place. Somewhat new to working on the component level. Been working on computers and such since I was a kid.Leave a comment:
