SAMSUNG UE43AU7020K BACKLIGHTS BUT NO PICTURE

[sordids999]

Hi
Really stuck on this TV
I'm thinking it's a bad screen ?
Voltages all seems good
Tcon 12v ok
Remove one tcon cable at a time no half image on the screen just backlight and no picture
even tried the tape trick still no luck

Thanks

If I disconnect lvds cable one at a time on the tcon
CLK1 to CKL10 is 9.8v
If both lvds cables are connected then
CKL1 to CKL10 is 0.00v

maybe the spi flash on the tcon bad, they are prone to be polluted, try at least a replacement board..
