Last week we received a 32PFL5604H/12 in our repair centre. Everything was working fine, except No Picture at all.
We replaced the mainboard PCB with a new one that we received from our parts- distibutor.
After replacment of the mainboard we have a picture again, but the set is asking for Firmware.
De system starts up with the Software Upgrade Application Q5431- Current software version is empty. By local upgrade it gives the message "No software found on Media"
I've tried the last version downloaded from the Philips website, also tried an older software version. But with both the same message.
Also used multiple USB Flash disk's. (large, small, all formatted FAT)
What am i doing wrong? Did i receive a wrong (new) mainboard? (313926864712)
