I work at an authorized service center and I can tell if a manual is as it should be. This one is. It may be a scan, but a very good one at that. The interesting part for me was the curcuit diagram which was scanned at high quality, making it as good as the original. I will definitely be back as a customer. I need not say this, but I will: the price was the best. Thank you owner-manuals.com .

Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.

Very good manual with clear electrical diagrams. Thanks owner-manuals.

TROUBLE SHOOTING TABLE (Continued)
A
Check the LEDs (D5001, D5002) on the main PWB. Does the D5002 light up in green? YES A DTV signal (available in the selected channel) is locked.
NO
There is no DTV signal for the selected channel. Some troubles exist on tuner and/or VSB (IC5002).
Does the D5001 (red) go out? YES The tuner and VSB function well. Check IC5201 and IC5211~IC5213 for trouble.
NO
If D5025 starts flashing or stays on in red, it means the reception condition is bad with many errors.
* Because of poor reception condition, DTV programs may be affected by the VSB out of lock (D5002 off) or reception error (D5001 on or flashing). Possible causes include: that signals being received by the antenna are too weak or too strong. that received signals contain remarkable ghost and other interference.
Make sure the video cable is properly connected. Make sure the video output mode corresponds to a monitor being hooked up.
No video output (audio output available)
Check the Video decoder (IC5401) and SDRAM (IC5402,IC5403)
