Getting Black Screen after thermal repaste

[realzootcat]

I have installed ps3hen on this ps3 super slim and it was kept freezing after opening multiman, so i decided to clean the ps3 by repasting the thermal paste and now it is showing black screen, it powers on normally and controller also connects.

Maybe you did not well Applied your thermal past so the cpu/rsx are overheating ?
