Re: Toshiba LED TV, blank screen
I have the Toshiba 46L5200U, Manufacturer Date Feb 2012.
Disconnecting DIM didn't work for me (neither the 14 pin on the power board nor the 15 pin on the control board; yes, I read that is basically the same thing, but I wanted to be sure). Not even intermittently. Having read this entire thread (and several others), pulling a pin is clearly a fix for some of the TV's - just not mine.
Since my symptom is intermittent (but easy to replicate), I was able to adjust the Backlight setting (Menu --> Picture --> Picture Settings, Backlight) to keep the TV running.
Setting Backlight to 0 (zero) kept it going all morning. Setting Backlight to 40 killed it right away. I'm now about 1.5hrs into Backlight setting at 30, and it has stayed on. The default factory setting is 70 (both before and after the firmware update, which I have applied: http://support.toshiba.com/support/m...eeText=3308679 ).
To me, this is still a temporary fix.
My hypothesis:
Remove the LCD panel and replace the Toshiba 2012SGS46 LED Light Strip Bar & it will be like new. (at which time, I would probably change my Backlight setting to 50, not 70, the default).
Any thoughts?
Feedback welcome and wanted.
