INSTRUCTIONS FOR RECOVERING FROM CRASH
The receiver will crash from time to time and lock up, no picture just black screen, the front panel maybe stuck on MAIN or flashing 8888 or something along that line. You may think its toast but it’s not. I am going to explain the easiest way to fix. Follow these steps:
You will need these files: There should be a SonicView loader, S/W SonicView clean file, S/W factory firmware and your channel list.
1. Unzip the files and save the extracted files to a USB flash memory stick.
2. Power off the receiver from switch in the back, and insert the USB stick to the front port. The FRONT USB port is the DEFAULT port. When the system is buggered, it will default to look here for data.
3. Press and hold the OK button on the front of the receiver while you power-on the receiver using the rear switch until you get USB info to show on screen.
4. It will say no USB detected for a few seconds and then it will find it. Select the S/W clean-file, and load it. You do this using the OK button on front panel to select and the black ring around the OK button to scroll up/down right and left. Follow the instructions on the screen and wait for several minutes after the load completes and then repeat steps 2, 3, but this time select either the factory firmware or your 3rd party firmware and load it from the USB stick.
5. After factory or 3rd party firmware loads just select English as language or wait a few minutes and this is an automatic default language. Then reload your saved channels from the USB stick and your back up and running.
You definitely need the clean file as it wipes out any corrupted file, do not try reloading firmware unless a clean file swipe has been done first.
You may thank Walrus for the information. Some additional files are attached, you should already have the loader and the cleaner file etc., but there is more information in these attached files.
