An update --- sorry it will be quite long and detailed, but help and advice are seriously needed.
On Friday I had the desk going for most of the day (about 6hrs) and all seemed to be working perfectly then at about 10.30pm I decided to give it one last HD24 play (the desk had not been touched/altered since the previous successful play). Hit play on the HD24 and immediately there was audio amd the meters were moving in sync with the recorder, then at 30secs in the desk froze --- why when it had been working correctly for about 6hrs. Shutdown and rebooted and again played the HD24, this time it froze at about 18secs. Shutdown and went to bed very frustrated .
Saturday I decided to bite the bullet and install the purchased DSP board. Soldered on the missing 22UF electro and installed the board. On booting the board showed only the Red LED (perfect as the old board had both the Red and Green LEDs). Again the desk worked OK for a number of hrs, then it froze. Rebooted and tried again and again it froze at about 12secs.
I then decided to disconnect (ie pull out of the socket --- not completely remove from the desk) all of the boards from the Back Pane (apart from the Mackie clock card ). I then installed the 1st 12 analogue TRS plugs from the HD24's Line Outs into the HD24 and the desk's inputs 13 - 24. Booted the desk and played the song --- perfect --- did this shutdown/boot process about 4 times and each time it played perfectly, so I decided to see if one of the cards was faulty, so removed the analogue inputs and pushed in OPT-8 No. 1 card (ie tks 1 - 8) and played the Hd24 --perfect. Then did the same individually for the other two OPT-8 cards --- all Ok. Then repeated until I had done all possible combinations, including all three cards --- all perfect. Then repeated the entire process with the card installed in the Alt in/out slot and then with only the card in the Dig In/Out slot, and then with all three OPT-8 cards and both extra cards --- all perfect. Then waited about an hr during which time I had switched off the HD24 at its main switch (it has a main switch on the rear and a standby type switch on the front). I then tried the mic again --- still good signal --- and while still talking into the mic I again turned on the HD24's main switch. Immediately the desk froze --- all that was connected between the HD24 and the desk was the two MIDI cables and the six optical cables --- why did simply turning on the HD24 cause the desk to freeze !!!!!
After that I could not get the desk to boot up with the DSP board having a Red LED (hence no audio --- I did not retry the analogue Line inputs to see if they worked --- my mistake !!!), so I decided to put the bottom plate back on and flip the desk in reddiness to take it to the tip. However during the day I decided to give it one last chance and booted up, but got no sound (I now could not see the LEDs but guessing that the DSP card that had been working perfectly on booting since installed was now showing only the Green LED.
Then stupidly I re inserted the MFX and UFX cards and wondered if the UFX card had ever gone through its upgrading process, so proceed to do this, It got to the part where it stated that the desk had to be re-booted, selected the re-boot option and on booting I got the below notification:
PMI Function = 0001
INVALID SECTOR = 001C
PMI Function = 0006
INVALID SECTOR = 002C
PMI Function = 0006
INVALID SECTOR = 0034
PMI Function = 0599
INVALID HANDLE = 0027F420
The desk did not reboot and I could not shut it down all that I could do was to manually turn of the Rack Unit. Now on booting there is no audio but on a few reboots I got the VUs showing full or near full and I still can't recall what that condition signified or its possible fix !!!!!
Do I now have to re-install the OS and if so do I need to reinstall the Hack 2 software ---if so will I need to again discover how to install the hack2 as the piece of paper with the instructions has long since been thrown out !!!
As the freezing problem seems to mainly occur when I am playing back a song through the OPT-8 cards, could there be something wrong within the Back Pane board that plays up especially after the desk has been running for some time (rembering that I think all but one ribbon cable coming from the Back Pane go to the DSP board) and if so is it considered worthwhile spending about another $180 to buy and ship another Back Pane board, or could the problem be somewhere within the Rack Unit and/or the motherboard (eg a faulty memory board ot RAM chip or similar. OR am I simply wasting my money and simply remove the plugin cards as possible spares for my own desk and take the desk to the tip, because unless I get some very good advice I really have no idea what to do next apart from re installing the OS and discovering how to do the Hack 2.
Any advise within about the next three days will be VERY greatly appreciated even if it is negative advice (ie dump the desk --- something that I really do not want to do !!!!!!)
