Treadmill Not Running?

When I power up the Treadmill, Everything is Normal... the HV BUSS Light comes on, on the Control Board, but when I press a speed, the treadmill Kicks on for a Second, but then stops... The Gate Ligt turns on quickly, but then turns off... & the SIG Light turns quickly on and off like a strobe light. I've asked a few treadmill sites in regards to this Power Output, & they are stating that the Control Board is No Good... I Just purchased a New Control Board, but the Same Thing Happends... Please Advise, Thank You.
