Just picked up a Sharp LC-40E67U.. I can get sound on all inputs tested but no pic.. The backlights come on and the screen is glowing bluish black. I would like to try to upgrade the firmware before I dig into this. But not sure how to do it since I cant get a pic to go into the menu... I have the firmware on a usb unziped to the root of the USb. Someone willing to tell me how to do this without being able to do it from the menu??

Re: Sharp LC-40E67U Sound NO PIC
DONT DELETE .. Got one more question.. I popped the back of and went right to the Tcon.. The TCON has 2 ribbon cables. If I undo the left one, I can get half screen to come up .But if both are connected the screen just glows dark blue/black and I have sound. I cleaned all the contacts and it didnt help. Do you all think its the TCON.. I have not worked on any TVs for awhile and my MM is still packed away in storage from a move.. If you all think its a tcon I will just order one since I can test any of the fuses or anything requiring a MM.

Re: Sharp LC-40E67U Sound NO PIC
If you can get half of the screen to come on with normal picture which just one for the cable connected between the T-CON and the LCD panel, then you do have problem in the LCD panel which is not much you can do to fix the panel.Never stop learning
