Strange BPPC happenings....

[Brian Hoskins]

I have never heard of this problem with BPPC cards.  What exactly happens when the card goes faulty?

We do get general problems with Flash memory chips in some models of TVs we service at work, where a reflash will temporarily cure the problem.  This is not necessarily "heat damage", sometimes these devices just get damaged through general use.  They don't normally get hot on their own, and I'm not sure of the location of them on a BPPC board.

I have a BPPC Board here - I'll see if I can find out which is the flash IC! If the Flash is faulty, normally a replacement will restore normal operation

Ryu,

I think I may have found the Flash Mem IC.  I just had a quick look on the board, and I recognised an AM29F040 Flash Mem IC on there.  Looked it up on my IC database and returned the following results:

Am29F040

 4 Megabit (524,288 x 8-Bit) CMOS 5.0 Volt-only,

 Sector Erase Flash Memory

 DISTINCTIVE CHARACTERISTICS

 s

 5.0 V

 Â±

 10% for read and write operations

 â¤" Minimizes system level power requirements

 s

 Compatible with JEDEC-standards

 â¤" Pinout and software compatible with single-

 power-supply Flash



------------------

This IC is a slim, rectangular shaped device located on the RAM side of the board, to the right of the PPC Fan.

It might be worth confirming with someone who is faimilar with the workings of a BPPC that this is the main flash mem for the BPPC board (I think so).  If so, it can easily be replaced by a trained person with experience in SMD soldering.

I assume that once a replacement was fitted, a reflash would be possible and hopefully problem solved!

Talk to me on #AmiHelp and we'll discuss it
