DMC500C - Help

[vinyx]

Guys, 2 days ago when I turned o n my set, the front panel light (yellow) was on but the TV showed nothing. Then I realized that the set did not response to the remote control. I tried to on/off using the front panel button, it did not work as well. It seems that the box has hung or something else. Anybody can help? The set is only used for a month. Thanks

On/Off the main power switch.
Should reboot & be ok.

on/off still the same. Have tried to flash once, it now responds to the remote control i.e. when pressing the keys of the remote, the yellow light at the front panel is blinking. However, still no output to the TV. Was given another img to flash. Will be trying today and see how it goes. Otherwise has to sent back to the manufacturer. Anyone has similar experience? Thanks !!
