I hadn't used my PS3 for about three months and when I tried starting it a few days back, it didn't give any display. So I did a hard reset and the usual screen showed up asking if I want to use the HDMI output. When I I select yes, the screen goes blank and nothing happens. If I select not to use the HDMI, I still do not get any display but I can hear the startup sound and if I use my controller, I could also hear the menu sounds. I have tried both the options quite a few number of times with the same result. Sometimes when the screen asking if I want to use the HDMI output shows up, it is very spotty and there is tearing.
I have tried using a different HDMI cable. I even tried it on a different TV with a different HDMI cable but got the same result. I also unplugged all the wires and then put them back in.
Are there any other troubleshooting tips before I take my PS3 to a hardware guy?
My PS3 is n CFW 3.55
