CECHC04 beeps and blinks just after power on power supply

[Krzyhu]

Hello,

Im new here, so at the begining sorry if I ask for some basics (but I googled and I found nothing common to my issue)

So I bought not working CECHC04. It dosent work at all, no reacting on power cable, after some cleaning it started to work a little.

What could be a reason of this behavior?

It beeps & blinks just after switch main power button behind.
I tried diffrent PSU - nothing changed.

Thanks for help

Hi,

There are the same symptoms when unlocking the internal mode for the syscon (before fixing the checksum). So maybe an issue with the syscon (like a bad checksum)?

(I'm pretty new to ps3 debugging, so take that with care .

Thank You. I will buy FT232RL and try to connect. I hope it will work while all this blink happens.

My PS3 CECHC back to life, little more.
I connected with FT232RL in internal mode, fixed eepcsum, exit. Now it turns like it should, but after 10sec shutdown with double beep, so probably overheating. Last error was A0801200
Other errors: A0801103 , A0801701 , A0902203

So tomorrow I will delid IHS from CELL
