I have a ps3 CECH2006A. The problem i have is when i turn on the ps3 it wont directly show up to the xmb. I have to wait around 1.5 to 2 minutes then it appears. When i adjust the display to HDMI it just black screen in AV mode is normal every thing is normal I try to put it in recovery mode it wont let me, it just on then 1.5 minute later off (no beep for adjust display or twice beep to recovery mode just on or off) i think the problem was the main board, just don't know how to fix it.
If any one have experience this kind of situation and know how to fix it please share your info.
