I bought a DSM-510 in January of 2007 with firmware version 1.01 if I remember correctly.
I connected it to a LCD TV and used the HDMI connection.
I successfully upgraded to firmware 1.02 and it continued to work well.
Unfortunately, after I upgraded to firmware 1.03, everytime I turn off the DSM-510 and then turn it back on, it takes me to the initial setup screen.
It is not saving any of my settings, especially annoying is that I have to connect the composite video to see the setup and then set it to HDMI and it works with the HDMI output until I turn it off or lose power to it.
I contacted tech support and case DLK398813692 was assigned. I tried using the "reset" option in the menu to reset to factory defaults and then configure it with my desired settings and the settings were still not saved after a power off and power on cycle.
I kept hoping another firmware upgrade would solve my problem, but even after doing available firmware upgrades in order, including version 1.07 I still have a problem.
After firmware 1.07, it seems to be saving most of my configuration settings, but most noticeable is that it NEVER keeps the setting for video to the HDMI port, and I always have to connect the composite video temporarily to select the HDMI output.
I have called the 877-453-5465 on 3 different days and stayed on the line waiting for a representative for an hour or more each time until the support system disconnected me.
Should the DSM-510 keep all user configuration settings through a loss of power and also though turning the unit off and on with the remote control?
My 1 year warranty is about to expire and I need some resolution to fix mine or get a replacement.
I'll try any suggestions for getting mine to save settings!
