I have a FAT 60GB BC TEST PS3 that has been acting weird lately. I'm not sure if it's about to give up on me or there is something I can do. I have been using it over HDMI fine for the past 6 yrs but now it will only displays black screen whenever I turn it on. There is signal from the PS3 to the TV as the TV showing '1080p/60Hz input'. If there is no signal, the TV will show 'no signal'. If I do a reset by holding the Power button for 5s, the screen will come up again and everything will work just fine. However, when I turn it off and turn it back on, the black screen will continue unless I do another 5s reset. I have done the following without luck: 1) changing the HDMI cable, I used 4 different cables 2) using Composite and Component cables 3) updating the FW 4) replacing the HDD 5) changing the display resolution to 480p, 720p, and 1080i 6) factory restore 7) use a different TV additional info: after doing the 5s reset, the system works just fine. Playing games like GOW3, U2, U3 and Beyond: Two Souls doesn't have freezing or image artifact issue. UPDATED: I tried basically every FW that I have (from 1.00 to 4.50) and the ONLY fw that it boots every time is 1.00. This is so weird. lol any help is appreciated. thanks 2ND UPDATE: After a day wrestling with it. I can't figure out how to fix the issue. To avoid more time wasting and after confirming that it's still under Sony's support, I submitted a ticket for repair/replacement. It'd should be good from now. Thanks everyone for the suggestions. Mod can close this thread if needed. FINAL UPDATE: The problem causes by a defect video encoder chip according to Sony.
