What should I do if the green light on the LEXIBOOK CHESSMAN PRO electronic chess set does not turn on or move?

Question

Accepted Answer

If the green light on your LEXIBOOK CHESSMAN PRO does not turn on or move, it may be due to a power issue or a malfunction. Here are the steps to diagnose and resolve the problem.

First, check the power supply. The CHESSMAN PRO operates with 4 alkaline LR6 1.5V batteries (AA format) or a 9V 300mA center-positive adapter. Open the battery compartment located under the board and check that the 4 batteries are correctly installed, respecting the polarities indicated at the bottom of the compartment. The batteries should be new or still in good condition: if they are used or weak, they will not provide enough power to turn on the lights. Replace them immediately with new batteries. Make sure not to use rechargeable batteries, as they provide insufficient voltage.

Test a complete reset. Properly close the battery compartment. When closing, you should hear a little melody indicating a new game. If you hear nothing, open the compartment again and check that the batteries are making good contact with both ends of each compartment. A poor connection is often the cause of the problem.

Understand how the lights work. At the beginning of a game (after pressing NEW GAME), a green light will turn on at the bottom left (light for row 1) indicating that it is White's turn to play. During the computer's thinking time, the green light at the top left (row 8) will blink. If you do not see any reaction after 1 to 2 seconds, the problem is most likely with the batteries or a poor electrical connection.

Clean the electrical contacts. Unplug the adapter if it is being used. Remove the batteries, then gently wipe the metal ends of the batteries and the spring contacts in the battery compartment with a slightly damp cloth (no detergents) to remove any oxidation or dust. Reinstall the batteries by pushing them in firmly.

Test with the mains adapter. If you have a 9V 300mA center-positive adapter, try plugging the device directly into the mains instead of using the batteries. If the lights turn on with the adapter, this confirms that the problem lies with the batteries or their installation.

If after all these checks the lights still do not turn on and you do not hear any melody at startup, a technical defect in the circuit or the LCD screen may be the cause. Please consult LEXIBOOK customer service or an authorized dealer for repair or replacement.
