JVC-32C675 Backlights on but blank screen

[4thommo]

Hi all,i have this problem and so far I have visually checked the main board and flashed the main board with the files in the first picture. The flash seemed to go ok,first the front red LED flashed quickly and then slowed up before the TV turned itself off and on but it is still the same. I see there are exact matching main boards available but I don't want to commit to that incase it's something else. Any help would be greatly appreciated.

Can you post good straight on focused pictures of each whole board and one of the whole back as to see how everything is connected.

Thanks for replying, hopefully these are good enough

Ok, I thought it was a vestel from the description in first post, to me it seems like a mainboard issue but honestly I very seldom even see vestel tvs here. Best to let the vestel guys help, wish I knew more about them.

You rewrote software for another type of screen and you no longer have an image. You have an HD panel and I think you wrote software for FHD. I have software for what is on the TV but it is for a different TV model. You try at your own risk. If the remote control no longer works, you can use a programmable one. There are 2 software in the archive. If the OK key on the remote control is no longer active, you cannot rewrite the software.

Hi,thanks for getting back to me.
I have never had an image on this TV since it was given to me,just the backlights on and a blank screen.
Thanks for those files,I have tried them both on different USB drives but the TV just acts as if I'm turning it on.
I went back to the file that I flashed originally to make sure the ok button was still working,the front led flashes fast then slower without the backlights on,it seems like it's taking the firmware but there is nothing on the screen.
I guess it may not be a firmware issue and could be an issue with the board, maybe.
