35 Troubleshooting
35.1 Software Version
Before troubleshooting be sure all components of the COM3000 are running current software.
Software can be found on the Technicolor website or from your distributor.
35.2 Verify RF
Before troubleshooting the COM3000 verify satellite signal passes EIV check on the DIRECTV
AIM meter at the COM51 input.
Use a test TV and field strength meter to test picture quality directly from the COM3000 QAM
output.
➢ Signal from the QAM will need to be attenuated to correct levels
➢ A DCI401MCS set back box is a good troubleshooting tool to verify picture quality.
35.3 COM51 Reset Button
Figure 77 below shows the COM51 reset button, accessed via a small hole in the front of the
card below the AT&T logo.
The button serves three purposes:
➢ Momentarily depressing the button results in a COM51 reset, like a power cycle or a software
reset
➢ Depressing the reset button for 30 seconds will result in a factor reset
o All settings will revert to factory
o IP address will revert to default for chassis / slot
o License files will revert to HD Streamout
➢ Holding the reset button for 60 seconds will result in a factory reset and force a recovery to
download an image from an external TFTP server. Server must run on a PC with an IP of
192.168.1.254.
➢ File should be the latest COM51 software with the filename changed to “COM51.bin”
