As the player is stuck at ‘HELLO’, it is a clear sign that its loaded firmware is damaged. There are several things that may have resulted in this, such as if the disc did not write correctly, the firmware file itself was damaged, etc. When downloading firmware, do not use any sort of download accelerator and also avoid using a proxy if possible (if your browser uses one). If a proxy based connection is lost, the browser will automatically show ‘Download complete’, even if only a partial download has taken place. When burning the firmware disc, make sure verification is enabled as this will make sure what is written to the disc matches the source exactly.
If you are lucky, the DVD recorder may have a recovery mode where if it detects a firmware disc in the drive upon powering up, it will attempt to load this. However, this also assumes you can eject the tray. If you can get the tray to eject, first re-download the firmware, burn this to another CD with verification enabled, pop this into the recorder, switch it off, then try powering it back up and see if anything shows on the screen besides ‘HELLO’ or if anything else happens over the next couple of minutes.
If your DVD recorder cannot eject its tray, it would be worth holding down the recorderâ€™s ‘Power’, ‘Eject’, etc. buttons for several seconds while plugging in the DVD recorder. Unfortunately, if there is no way of ejecting the tray or getting the player to recognise a firmware disc, you will need to get it sent back for repair, since the actual Flash chip may need to be removed and programmed directly, something that can only do with specialised equipment.
Assuming you were not trying to load a modified firmware, you should be able to get your recorder repaired or replaced under warranty, assuming you bought it within the past year. The best thing to mention to the store is that the recorder will no longer turn on, as it will be easy enough for them to check. Don’t mention anything about firmware update unless they ask. Then again, as there is nothing stating that a user cannot do their own firmware update, this shouldn’t void the warranty, although this is less likely the case if you have used modified firmware and they discover this.
