Hi, I've recently purchased a CECHC03 backwards compatible PS3, it was effectively dead. I've de-lidded both CPU/GPU and reflowed them and its now working beautifully, temps are cool across the board and I've been gaming on it trouble-free for a couple weeks...except for one issue.
When I switch it on (either via the power button or dualshock) it boots fine but there's no signal (on HDMI might I add), if I power down and boot using the double-beep safe-mode the picture then appears, I select option 1 to restart the PS3 and it boots and I play normally without any problems for as long as I want, no artifacting or anything. If I switch it off and reboot it, it also comes back on without problems, but if I leave it for an hour or more its back with the black screen no signal and I have to perform the double beep again.
First I thought the GPU needed reflowing as I may not have done it for long enough initially, however surely if the GPU was the problem going into safe-mode wouldn't help, but the double-beep method brings the HDMI picture back EVERY.SINGLE.TIME!
Somehow it seems to forget the HDMI settings when powered down for a while. I'm thinking it's something to do with the power rail, this is supported by the fact the settings are retained if powered back on after a few mins or left on standby, but if I let the board drain of power it needs to boot via safe-mode again. Is the CMOS chip responsible for remembering such things? I have replaced the battery but the chip itself might be busted?
Has anyone else come across this at all or know what would cause it? Its not a major issue, I have no intention of selling it or anything and its a fully functional backwards compatible PS3 at the end of the day that just takes about 90 seconds longer than normal to boot. But if it can be fixed I'd certainly like to get it perfect.
