TV not displaying picture

hi. i’ve bought damaged tv philips 50PUS6262, upon checking inside the fuse was blown, i put another one in and it immediately blown aswell so i ordered new power supply board. i changed it and now the tv turns on but no logo only backlight is glowing. inside there are 2 green lights on the motherboard. and i can’t turn off tv with remote,it just doesnt respond. i also tried connecting all 3 hdmi ports to a laptop and pc ..no picture whatsoever. what could it be?

Hi,

could you solve the problem? I think I have the same one. The TV goes on but there is no picture visible. The backlight in on, you can see how the tv gets brighter.
