Re: Sharp 70" model LC-70LE733U 2-5 blinks

Ok, I'm new to the forum, but I've been reading the posts and I'm still having issues with my Sharp LC-70LE733u with the 2 long/5 short lights. I have replaced the main board, the power supply board and the LED address board with no success. Also, when I attempt to get into the diagnostics menu by holding the volume down and input buttons, it doesn't work. It went in one time and then would not repeat. I have a t-con board coming, so I'm getting a bit harried with this thing. Any other suggestions? By the way, I'm pretty technically adept as I build, repair and maintain PC's and laptops. Thanks for any help you can provide.

any update on this? i have the same model and can't get it to turn on. Clear the 2-5 code and still nothing. Even with cable from Tcon disconnected.
