Title: Toshiba 39L4353D - No go.
Post by: Turnip on November 04, 2015,09:06:01

Hi Folks,

Have one in where after a reported power cut while set was working, it stopped. Plugged it in and found after a few seconds the LED backlights came on but with no picture or OSG.

Green led on main board initially flashed twice repeatedly then after a few minutes flashed three times continually.

Neither set buttons nor RCU have any effect - Any thoughts ? - Thanks - Chris.

Hi Cat,

Did as you suggested - Surprised at a 150Mb firmware download but it did the biz - Many thanks - Chris.
