Element ELEFW503 Backlights work No picture

[tvfixer007]

Turns on and backlights work, but can't get a picture. I went ahead and replaced the mainboard/power supply since they are both on the same board. TV does the same thing with the new board.

I believe there's a fault in the timing control but this TV doesn't have a separate t-con board. Anyone familiar with this model TV, or other models with same parts?

Is there only one board ? Post a pic of the back of the set.

Had the set outside, got some daylight now. There's only one board that is interchangeable.

on the same pcb as the fuse if you disconect the white ribbon cables do you get anything on one half of the screen? im not sure if this test will work or not but maybe worth a try also do you know the back ground of the tv? it looks like the tab bonds are on the bottom of the lcd do any look burnt etc as some people use screen cleaner which runs down the lcd panel and damages the tab bonds etc.

I do not know anything about the TV. I tried disconnecting the ribbon cables but still nothing shows on the screen. The tab bonds do not even get warm, but I can try to get some close up pictures of those boards. Nothing looks burnt at all.

I was able to get more images. In the second image what is PWRON GVOFF?

The arrows pointing to where I tested voltage in the included image. The voltage reads 11mv with TV on, and when I power off the TV it ramps up to 8v and climbs back down.
