Hi Steve,
Not a nice set, met a few, mostly now recycled hoping something better.
Had the 'stuck in s/by' issue so got the programmed Eeprom. Then found I had the 'backlight cycling' issue when it fired up.
Folks who supplied the Eeprom suggested 'Don't bother replace if you have a backlight cycling issue' as the M/Proc is duff.
Not yet a winner - Anyway, copied the new Eeprom, also the one for the 40 inch version, but that didn't work either. Attach your screen version - Best of luck - Chris.
