V15 Graphic glitches doesn't load games
I have a problem with my ps2 slim
V15 77004 PAL
And there was no modding tryouts in the past
ps2 will not start up with a memory card inside (tryed many cards). It will only show black screen.
When i remove the memcard, it starts up, then the sound goes bad after the sony logo comes up and the menu appears with some graphic glitches.
When I put any PS2 game it reads it then shows the "PlayStation 2" logo and nothing happens only black screen.
I suspect there is a problem either in BIOS or NVRAM I have another ps2 that I can use for parts so please anyone tell me where I can find NVRAM or BIOS.
