Hi Guys , have had trouble with these sets before but have got one with sound and no picture . Screen black no backlight at all . Is there a way of testing if the screen is faulty because it seems to be the same as the latest Toshiba where the equivalent of the inverter board is built inside the screen itself. Thanks for any advice

Hi, I have the same TV, but when powered up the led flashes 9 times and stays on but the TV doesn't come at all,  any advice will be highly appreciated.         
Thanks

Papisco ,all I can help you with is you should get 28V on the end of the 4 diodes . Have had the main board cause the same fault as you have

call me al:
Hi guys As this is a led backlight its proberly a fault with the led strips. You will need to strip down to the leds and apply 20v to each strip to see if they all light, good luck

Hi Cal Me Al ,problem is I had the same problem with a Toshiba . Stripped it all down but the lights are glued down
