Dear All,

I am new to this forum and hope I can get some help here. I purchased a new Heng Long T90 pro version very recently. On the first day, everything was fine and the tank was able to demonstrate all the functionality. On day 2, when I turned on the tank, the tank front headlight was flashing, but I cannot activate the tank from the remote. Whenever I pressed the power button on the remote, I can hear the tank tried to make the engine startup sound and then both sound and front headlight went off. After a few seconds, the tank headlight started to flash again and if I press the power button on the remote, the same issue happened. I tried to charge the battery and even tried a different battery, but it did not resolve the issue. I also opened the tank and did not see an obvious loss wire connection. Did I miss anything? Is there anything else I shall check for troubleshooting? Thanks.
