[fester]

Hi friends,
i have problem with this TV,after pluging in,try to start-i see white light for some seconds ,after this only blinks,one short white blink,between blinks is red led lit.
I dont know what this means,cannot find some service manual or something about this problem.
Power board look ok,nothing visibly bad,voltages 12,5,5VSB are present.
I made some photos of boards,any help would be much appreciated..

That code is backlight failure. It's called a 1-1 code. One long flash followed by one short flash. The back light output pins from power, supply do you see a momentary voltage, and drop off?

1) TV is OFF, set the DC Volt meter to at least 200VDC scale.
2) Keep the black probe of the meter on the chassis, keep Red probe on the LED connector (do not remove the connector) where the RED wire is then turn the TV on while watching the meter to see how high the Voltage jumps up to and wait 10 seconds to see how low it goes down to, report the reading. Turn off the TV.
3) Repeat step 2 but this time you will move the red probe to where the white wire is on the LED connector.

Don't think this tv uses a fault code as none of it is made by sharp.

Cheap LG panel, megmeet PSB and UMC mainboard.

In other words a pile of steaming ****

These mainboards have issues with corrupt Nand (u3)

I dont think that this is the 1-1 code,is only one white blink repeated forever. I uploaded short video of this blink.
Also tried many key combinations for sharp tv but without any effect.

Yep. I second corrupt firmware. If Sharp has a firmware file for this particular TV load it on to a USB, plug it into the TV and plug the TV into the wall do not touch anything until finished.
