Dm 24 doesn't start "dsp boot error"

[Macross]

HELLO TO ALL, I WISH TO ASK THEM IF SOME OF YOU KNOW ABOUT A PROBLEM WHEN STARTING THE CONSOLE WHERE IT IS BLOCKED AND NOTHING APPEARS ON THE MONITOR THE IMAGE OF THE CONSOLE; IN THE DIAGNOSTIC MODE APPEARS AN IMAGE WITH THE "DSP BOOT ERROR" MESSAGE, THANK YOUR ATTENTION EXPECTING TO COULD COUNT ON YOUR GUIDANCE THANKS

Looks like the DSP chipset have failed. Maybe open up and try to re-seat the DSP board (assumption here). On the DM3200/4800 there is a different error associated with the DPS chipset where re-seating and blowing out the DPS board connectors is the first suggestion. Again, not sure if that is the problem. Other searches for this issue also hint it may be a power supply issue.

Also found this about DSP errors on DM24.

Aberrant data is detected in the audio signal in the DSP. ● Remedy: Run the SRAM Initialization. If this does not fix the problem, check U6 on the MAIN PCB for signs of poor contact and if necessary replace U6 or further check U71-U93 for signs of bad soldering.

Friend many thanks for your interest and help, I will proceed to verify the inside of the circuit board according to the manual that kindly provided me, if I have any extra questions I could count on your help? thank you very much

I would run the SRAM initialization first as it suggests since it doesn't require opening the machine.

My friend, I did the SRAM initialization, and I was not lucky, the equipment is still the same, then I opened the computer and realized that in the main pbc there are some cables that connect from one integrated circuit to another, as if they had been put later And I think it is not correct that they appear, I'll send you some photos of how they look; I have also verified the u6 chip that is in its position and has no problems of false contact; After that I imagine that one of the 3 eproms is damaged and I believe that they no longer sell those refacings for what I have been investigating, the only thing I have found are the chips but you have to program the information coprrecta according to I think, I appreciate your help valorio much Greetings!!! thanks and blessings
