All your video shows is that the panel 12 volts was turned off.

Don't heaton main CPU....from SM- high-speed blinking-Flashes 5 times mean -Panel power supply error....check LCD Power Controller....

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

It is not possibile to repear this board !
Too demanding. I'll try to find a new one.
I look on the internet but I can't find anything .. it's crazy!

Awaiting review from R_J and BUDM

Excuse me I do not understand well represented what you wanted to say with the right side of the T-Com board?

redo the test of removing one cable from the tcon to panel. Your observations don't appear good. Post a picture of the display that you get. Further, IF the set is in "error mode", you might have to follow a "force sequence" to get the set to start up correctly.

So, if I understand you correctly, did you say that I should disconnect the flat cable from T-Com again first and then the other, and that I should watch the light blink?

If I disconnect the T-Com kit from the Tv main board, it flashes the same 2 x long 5x short regardless of whether or not the T-com board is connected.

BUDM: this is ok power board ??

ok now i measured the voltage a little more carefully.
when i turn on the tv in 220v
the first 5 seconds I have a voltage on the following pins like this

PIN 1, 2 PNL12V = 12V
PIN 3 = 0V GND
PIN 4 = 0V GND
PIN 5 =12,89V
PIN 6 =12,89V
PIN 7 =12,89V
PIN 8 =12,89V
PIN 9 =0V GND
PIN 10 =0V GND
PIN 11 =0V GND
PIN 12 =0V GND
PIN 13 AC-DET = 3,33V
PIN 14 PS-ON = 2,86V
PIN 15 BU5V = 5,05V
PIN 16 PNL-POW = 3.30V
PIN 17 = 0V
PIN 18 = 0,40V
PIN 19 DIMMER = 0V
PIN 20 = 0,45V
PIN 21 OFL = 0V
PIN 22 ERROR = 0V
PIN 23 = 0V
PIN 24 STB = 0V

here are the results of measuring the first 5 seconds when I plug the cable into the electricity. (Main board conectet whit power board)!
after 5 seconds i have voltage only on PIN 15 / BU5V = 5V
that's it

PIN 21 OFL = 0V
PIN 22 ERROR = 0V (generated by backlights circuit)

PIN 24 STB = 0V This is BL-ON signal generated by Main board

Are you saying after 5 seconds you do not even have Voltage at AC-DET pin? Are you 100% sure of that?
Also you do not have BL-ON, DIM, ERROR.. Voltages.
See typical Voltages on PD pin.
Are you still getting the same blink code?
Are you 1005 sure about your Voltage measurement?
Do you notice if the backlights even come on for seconds? You may want to monitor the STB pin and the Error pin when TV is first turned on each time.
Also already try resting using the remote, I do not remember the exact key combination.

BUDM:
Yes
everything I wrote is real. and I'm 200% sure. i mesure 5x
the code is always the same 2x long 5x short

no lighting comes on I'm 100% sure.
it does not light up for 1 second

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

Put the old power supply board back in and check the AC-DET pin.

BTW, did you actually disconnect the cables between T-CON board and the LCD panel as suggested? You only indicated that you disconnect the cable between T-CON and the main board.

i'm doing what you told me to do.
I unplugged the flat cable first side A and nothing happened. then I unplugged page B.
all the same.

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

Put the old power supply board back in and check the AC-DET pin.

Ok check in 5 minit...
Wait thanks.

[markolino]

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

Ok im Back.

i gave back the old original power board and the case is the same.

Okay. For the first 5 seconds I get a 3.30V to AC-DET pin
then it drops to 0V
