PH55X57DAG

Calls and writes philco and erases the philco logo and nothing else works, neither the remote nor the keyboard. | In my case I updated via pen drive and it accepted the update, tsound was that blue screen of updating up to 100% but it stayed the same. I noticed that sometimes after the logo was erased, tsound would be interference vertically and sometimes it didn't happen at all. I suspected the data clock line, but before seeing that, I remembered the reset and when I changed the capacitor c536 on the underside of the board the equipment started working again, as tsound is the reset circuit, I also resoldered it and cleaned it afterwards. So how did you solve it and I believe that in my case it was that. | Check reset circuit c556, n515, both underside of the board. Because as we know, the Philco logo is in the room and not in the firmware, which is why the update did not solve the problem. somehow after the logo occurred, the equipment would have to start reading the firmware memory and it didn't happen, so I thought about data clock, but maybe the reset somehow didn't happen perfectly and this prevented the correct initialization or command lines of memory. | MIGUELTV |
