at this case you need to feed the TV with HDMI Signal and you should hear sound,,, then the problem will be clear

Diah Since each led show 3v with Led Tester i measure it with a multimeter and there a small difference between the old and the new ones but i do not know if it is relevant :
New :2.504 v
Old : 2.526 v
do you think it can matter ?

No, this is normal depending on Manufacture and age.. do the test with HDMI signal... you should hear sound

You are really Positif i like that way . ok i ll do it but please about that Audio test how would you do it without access to the TV setting ? and if you get Sound what would be the Fault? because you say in post 41 " feed the TV with HDMI Signal and you should hear sound,,, then the problem will be clear" thank you

you wrote at first no Picture no sound... then we did know you saw Picture but no report about sound... may be because you take out the speaker from system..
so put speaker back feed the set with yours laptop and play movie with sound... plug the HDMI Cable at TV HDMI with label ARC, yours laptop will register the Tv as second Monitor , if no sound just play with RC Source , yours BL will shine and you will hear sound... this all if no screen on TV... but if it installed will be easy for you and even there are any issue will be not LED... so can be fixed while screen installed
