Xmb blue squares
So I got a 120gb slim, model is CECH-2001A, used. It appears to have light use, warranty sticker was still intact.
While on the xmb, I get some weird looking blue lines that make squares in the upper half of the screen. They r not too big, and kinda flicker.
The weird thing is that they r not there when playing blu-rays or games. If I pause a movie, I will get some horizontal blue lines, but then when I play the movie they go away. Games look fine.
I tried doing a full restore on it, and reloaded the firmware.
I also did open it up and replace the thermal compound with mx4, and cleaned out the dust.
I have also tried hdmi, component, and composite cables on 2 tvs. I also replaced the hard drive, everything stayed the same.
With the composite cable, the squares are bigger, since the lower resolution.
Any ideas? I thought gpu reflow would be needed, but games and blu-rays look great, so I am confused.
