I9505 LCD working only for second at start - GSM-Forum

Hello,
At first sorry for my poor English, i hope You will understand me

I have a problem with my Samsung S4 I9505. When i'm trying to start up phone, LCD shows image only for half a second, like flash. After that it's black, but phone start up normally, touch works, vibration too.

I tried factory reset, it didn't change anything. I also tried new software by Odin, it didn't changed anything.
I also dissasemblied phone and cleaned a plug and a socket from lcd, but LCD is still black.

There's something weird with it, because when phone is working and i pull out battery, LCD shows image for half a second like when the phone is starting.

Phone have never dropped, wasn't flooded etc. It looks like new one

I think it's some hardware failure, but it would be good to be sure what part i have to buy.

Thanks for help
