HELP !
Unfortunately it seems that the Flash ROM memory that contains the player's firmware is going bad (has a bad integrated circuit chip). The firmware contents most often have a calculated checksum stored with the code/data in ROM. The player at startup compares the read checksum with what it calculates from reading all the ROM contents. When the read versus calculated sums do not match, then it knows, and is alerting you, that some ROM location is going bad and not to trust the player to operate right.I got a Pioneer Elite DV-38A Player (DVD-A 196khz/24bits D/A converter - Progressive scan DVD) that does not work ans only shows "Flash sum" on the display.
I got that problem in the past, but after some times (hours) it was ok. But this time, it does no work for a week and only displays "FLASH SUM".
What this could be ?
It says in the manual to reset it, you must unplug the DVD player, plug it back in the receptacle, press and hold the STOP button as you press and hold the STANDBY/ON button for 5 seconds. See what happens!I read that if you unplug the player it may reset itself. You could give that a try.
