Backlight not working

[xusso]

Yes, it's true. My Wizard revived, but with a small problem: the backlight doesn't turn on not even after some Hard Resets and even on bootloader mode, the screen is dim all the time.
I've also changed the settings on the slider with no success and searched the forum and found no answers.

What can cause this and what is the "cure"?

Thanks in advance.

Thanks for the tip. Is there any way we can fix the light?
The screen works, the touch works, but it's far too dim to use it.

Anyone else?

You say you have hard reset it, but have you tried flashing a different original rom to it to see if that fixes it? It might be a hardware problem with the lcd but i did have an issue once on my himalaya after flashing a new rom and i couldnt get the backlight to work, but after flashing an original rom it worked again and then i reflashed a cooked rom and it still worked

I'll try that!
I've already flashed the original one...maybe flashing it with something else could fix it...
Thanks again

OK, just reflashed with a WM6 ROM (TNT.1933_Professional___HTC_Home_Wizard.rar) but it's the same. I can barely see what's on the screen. The screen works, the touch works, but it's too dim to use it.

So maybe it's not the backlight, I think it's the front light...

I also have dismantled it and cleaned out the contacts, re-assembled and flashed it again with no luck...

Help?

WM6 ROM (TNT.1933_Professional___HTC_Home_Wizard.rar) <---- that isnt an original rom, i am on about a operator rom that was officially released for your device, i.e. mine is an xda mini-s so my original provider would be o2, so i would use an o2 rom update that was released by them.

What you have basically done is install a cooked rom from itsright. Whoever the phone was released by try flashing their original wm5 rom to your device to see if it fixes it. THEN try flashing the tnt rom

Ok, some new developments. The LCD is fine and working and there's no problem with the backlight. I've manage to find that the issue was the mainboard all along.
I've used another LCD (a good one) and the backlight was still on, so the problem might be the mainboard is fried.

So, anyone can help me out? I just need a new mainboard (can be with the USB Connector in bad conditions, cause I have some solder skills).

Please help me out.

Edit: The Thing now doesn't charge properly. After some time, I get a flashing orange led and my Wizard heats up like it's going to blow...
