HDD070/05 philips go gear

The flickering screen would indicate that the unit is not faulty. Nor is the battery. This happens when the battery is fully discharged. The player does not recognise that the battery is there. Philips released a firmware update to fix this.

Download the update from here:

Ideally you need a spare battery so the player can be started up to update the firmware. To remove the battery, undo the screw at the top right of the player and unclick the end cap. The battery plugs into the PCB so is easy to remove.

If you don't have a battery, sometimes unplugging / plugging in the charger & battery can get the player started. Alternatively, you can obtain a battery to update the firmware from www.cheapestelectrical.co.uk

Although they are not on the website, they have a compatible battery (for an HDD1620) which can be used to power up the player to perform the update to v5.2. Then you can switch back to the original.

Go to the "about us" page and contact them directly. I know they have them in stock.

Ask for a HDD1620 battery.
