My bad,
After check it, I saw the board I bought is from a 650 series too. "LE40C652".
The chip were is the firmware says 650 "VAL.650 10132 0531".
This changes the scenario right?

C630 has no internet tv, but c650 does. You can not just simply change firmware because of hw issues, particulary of smaler nand size etc. What do you expect from c650 firmware ? Only difference i could see is lack of internet tv (which is not supported anymore and functionality is very and very li...

After several tests, I´ve found the problem. PSU problems. I bought a used PSU, and the TV works. At the beginning the image was very bad, full of vertical lines. I removed the flat cable more that once, unscrew some screws, and the image is good now. (I only tested with the menu because I have not ...

Today I did the test of the spotlight.
In a dark room, I didn't see any ligth coming from the TV, but when I put the ligth in the screen I was able to see the menu (is not pluged to any device or to a antena).
What can it be the problem?
Thanks

This is what I will do.
Is the best option. Otherwise I can have the problem of smashing the rest of the TV.
This causes me some serious nervous.
THANK YOU

Yes, but the short circuit was only in the board, and I´ve changed the board by another, the one I´m using now.
But now I´m thinking that tried the TV with a short circuited board could damaged other thing (but I don´t remember if i did it.
I don´t know what can I do now.

I just found a Brazilian blog, that says something like this: Problem: The Tv turns ON, but the screen is black. [/b] Suggestion: Flash the firmware. Is this possible? How can I do this? I have updated already the firmware some yers ago, but always via USB mode, with a working TV. Is possible to fla...

Thank you, It´s strange, because the TV was working perfectly, the only problem was the main board HDMI port loose. I took out the board, at the same time I was using a 36V power adaptator, doing other stuffs, and by mistake I "laid" the 36V cable wire on to the board (I tough :Sh$%"#...
