Default Re: Sharp LC70LE747 Flickering - darkening gradually to the right side

Bad news. The problem returned.
Backlight
- BL voltage on the 3 strings are identical, 190VDC and stable
- Looking from the back the backlight illumination is steady
I can't get my head around the following: when the TV starts without symptoms it will probably stay without problems (24h or more if you like), when it starts troublesome it won't recover, whatever I do. It's like something interferes with the boot sequence.
