Re: Sharp LC-50LB481 Two fast blinks Backlight Turns Off No Picture

I have similar problem, except by top LED String blinks, bottom is OFF all the time.

Right after plugging power source my VLED = 63V VLED1=15V VLED2=15V
After Pressing Power button: VLED jumps 91/83V -- top LED string goes on and off every second, VLED1/2=jumps all the time, my meter can't catch any stable value.
I see picture and can hear sound

Should I remove bottom LED string and test each...
