Try holding on the tv volume down-channel up and power, see if you hear a click and tv starts.

here's a try on your theory a little earlier.
first disconnected one flat cable.
error equals black screen light flashing. 2 slow 5x short
then i plugged the flat cable back in and unplugged the next, same error black screen light flashes....
so the led panel is ok?

is this "observation" correct.... note "light flahses..."

what do you want your comment to say ??

Yes

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

anyone know how to force the LCD panel to turn on the LED lights on TV only whit PowerBoard ??
Thanks

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

here i managed to force the powerboard to turn on the led lights
i think they all work.
the voltage gives 178V on each line

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

you have an issue on the right side of the set. It is likely a problem with signals getting to that side. Look at the tabs along that side. IF you input a signal, you will likely see the issue better.

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

This is, of course, not the reason for the TV not to turn on
I forced the lights LED only with the power board.

What do you think about the lights? do you think they are burned out?
on the upper right

When you forced the power supply ON, what is the voltage on EACH pin of L1

Pin1 LED1+
Pin2 LED1-
Pin4 LED2-
Pin6 LED3-
Pin8 LED4-

And Yes, I think you have burnt out led's on the right side of the panel.

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

Look at the pictures. So I forced him to turn on the LED power

I have 180V power on each + wire
hence 4x 180V

Pin1 LED1+ =180V
Pin2 LED1-
Pin3 LED2+ =180V
Pin4 LED3-
Pin5 LED4+ =180V
Pin6 LED2-
Pin7 LED3+ =180V
Pin8 LED4-

Do you think I turned on the lights?
I got that kind of thing that lightning damaged him
storm.

No Voltage reading on all four LED - pins?

[R_J]

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

What part of EACH pin of L1 did you not understand?

[markolino]

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

obviously we didn't get along well.
I have 180V on every positive pin
if you were interested in that?

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

led minus pin voltage i think we need too thanks

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

First of all, you have to explain to me how to measure LCD bodies properly.
I'm not a trained electronics major.
my savvy mind knows how to measure current + ter - with a voltmeter ..
How to measure if the LED bar is working properly, I don't know.
If you explain to me, he will be able to answer you.

I apologize for my English
I'm writing with the google translate.

Re: TV Sharp AQUOS LC-60LE635E TV not power ON

in post 52 you have measured the + voltages and missed the - voltages can you test these

You must have:
Pin1 LED1+ =80-90V
Pin2 LED1-
Pin3 LED2+ =80-90V
Pin4 LED3-
Pin5 LED4+ =80-90V
Pin6 LED2-
Pin7 LED3+ =80-90V
Pin8 LED4-

each led backlight strip is formed from two lines of 17 leds in paralel .....

leds have Vf=5.4-5.6V ..... this is a leds backlight stripe https://www.aliexpress.com/item/3302...3ff94c4duF6nD3

For LED TV Backlight you need a tester https://www.aliexpress.com/item/3302...68da2bcf2RsGqz
