I have being using this K40 with SM7 for 2 months whitout problems. I left the truck rest on my shelf for about 1 month and I could not get it to work again.
The menu does not work, only a row of red dots, 2 dots or sometimes nothing lights on the display.
The steering and gear servo ports are getting energy (servos self center when conected) but there is no response from the receiver or from the menu switch.
SM7 Is conected on the sound port of K40 and SM7 does not respond to the aceleration. If I connect the SM7 directly to the receiver it responds to the aceleration.
SM7 is working fine and receiver ports too when servos are conected directly.
Can you please help me to identify the problem?
Thank you
