PS3 retail CECHB00 backwards compatible PS1 and PS2 Japan 20BG not working

Product Name: PS3 retail CECHB00 backwards compatible PS1 and PS2 Japan 20BG not working
PS3 CECHB00 backwards compatible PS1 and PS2 Japan not working . The console was completely taken apart and cleaned. No dust inside. Thermal paste was replaced. Cooler fans were also cleaned. The console power on, you even get picture but after some minutes it crashes and freezes. It's probably something on the GPU but I have no knowledge on fixing this so I'm passing to someone that knows. It is in cosmetic great condition. I tried to replace the hard drive but it's not that the problem. This console is intended to retail play Japanese games only. Again the console is not working. And it's console only, no controller or any cables. Please read all information and check pictures for details. Any questions fell free to ask. This sale is final. No returns.
