Black screen - E3 Flasher and NOR replace

Hey

At first i want to apologize for my english (its not good). I have problem with E3. I have PS3 with RSOD. I have made a valid dump of NOR (soft 3.56) and downgrad it to 3.55. After that i have instaled NOTHEROS cfw but still RSOD. I can install any cfw but cant go into XMB (RSOD).

I decided to replace nor. After program nor with my backup i have black screen, hdd is blinking, usb working (i can install any pup file, i can enter and exit service mode) but i still have black screen on HDMI and composite.

I put my old NOR back and ... still black screen :O Any ideas ?

P.S: im useing e3 linker
