It has all the information you will need to fix it. The main circuit diagram is only A4 but being a PDF, you can print it to any size - I did it on two sheets of A3 and it didnt lose any detail - just made it readable when pinned up above the bench. I've found the fault, just need to buy some obscure bits to get it going again!
I cant fault the process, I paid for the manual in the morning and it was ready to download by lunch time.

Very good copy in a 54 pages PDF archive. This is my sixth purchase here. :)

Another excellent buy! File too clear and explanatory.

A manual hard to find. It was very helpful to restore my device.

I am very grateful for this manual. Without it could not repair my receiver.
MP440BX SPECIFICATION UPDATE
5.
System Will Not Format Unformatted 2.88 MB Diskette
PROBLEM: The BIOS does not support formatting unformatted 2.88 MB diskettes. The operation will terminate with the message, �Invalid Media or Track0 Bad. Disk not useable.� Previously formatted diskettes can be reformatted in the drive. IMPLICATION: Unformatted diskettes will have to be formatted in another system before they can be used. WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision.
6.
System BIOS Does Not Log ECC Memory Errors
PROBLEM: The system BIOS does not write a record to the DMI log stored in non-volatile memory when a single or double bit ECC memory error is identified by the memory controller. IMPLICATION: For single bit errors, the error will be corrected based on the memory checkbits. The corrected data will be passed to the system by the controller, but the error will not be recorded in the DMI log.
For double-bit errors identified during run time, the system will not be halted. The erroneous data will be passed to the system by the controller. The error will not be recorded in the DMI log. Because these errors are not recorded in the DMI log, the user will not receive information from this log that could be useful in isolating a failing memory module.
WORKAROUND: None. STATUS: This erratum will be fixed in a future BIOS revision.
7.
Onboard LAN Controller May Not Initialize Properly
PROBLEM: The onboard LAN controller intermittently fails to establish a network link at the time the system is started or rebooted. IMPLICATION: The user will not have access to network resources. WORKAROUND: None. STATUS: This erratum will be fixed in a future PBA revision.
