I came across a pioneer dvl919e player that doenst function anymore and only displays the word 'flash sum'. Anyone knows what this means and how to fix this? |

The flash ROM chip is corrupt, it needs to be reprogrammed. |

This sort of thing could eventually happen to anything that uses a Flash ROM. It takes many years usually, but it's a time bomb regardless. |

I have seen it and made mistakes on PC motherboards with the Bios Flashing gone wrong  Especially with Gigabyte MB and hence why they had dual Bios for a Backup later in early 2000.  Even the \../ makes Big Errors!!

I have a 909 player with the same fault. The Flash ROM is IC603 and part number is VYW1601-A. I have researched and it seems that these Eproms are the MBM29F400TA-70PF. I was just wondering if it would be possible to copy the data from a working one and then program it onto a new MBM29F400TA-70PF. |

Yes that should work fine. |

O.k., that sounds good. I only have to find someone who is able to do this and find a MBM29F400TA-70PF. Does anybody know if another Eprom would work? I just checked and I cannot find anything on the original one except the Pineer part number. |

Almost certainly not very helpful but Amazon Japan (not a random reseller either) has it... https://www.amazon.co.jp/FUJITSU-MBM29F ... B018FVGIGK |

Thanks for checking, but it is not the right one. This one is the "PFTN" version and the players need the "PF" Version. The "PFTN" would not fit. |

I ran across this error by mixing up the DVD boards. Pioneer revved the DVDM board in later players which have "(1)" on the back. I believe if you mix a newer DVDM with the older front panel assemblies, you get this. Flashing the ROM might fix it - I solved the problem by not mixing the boards. |

It's not so easy to fix in a 919. They have the chip soldered onto the board. The 909 has a socketed chip. There it's easy to swap. |

Does anyone have a complete dump of a DVL-919 or DVL-91 flash? |
