Displaybacklight doesn't work, how to fix it.

Hey there,

My TV just stoped working after 4 year. I still got sound and after lighting up the display with a lamp in front of it I was able to see the picture back again but it was very dark.

So my conclusion was that the backlight is broken. After a bit of reseach I opened the TV. But I can't see any broken parts or loose cable.

I added some picture of the TV's back.

Hope you guys and girls got some ideas how to fix it.

Thanks for every idea you got.

Btw the model nr. DVB-113201HCAS
