I am assuming you have a Jet 7 with a VSI controller (manufactured by Penny and Giles) with a steady flash of all the speed and profile LEDs (lights). This is a no drive away feature of the VSI if the charger is plugged in. The older Penny and Giles controllers indicate the same flash code.

If you have an on- board charger check to see if it is plugged into the wall. If it is, unplug it and see if the chair runs. Sometimes, you have to remove the back cover and unplug the charger haress at the output of the charger inside the electronics housing (much more difficult). A failed on-board charger can inhibit the VSI controller (no drive away) even if it unplugged from the wall outlet. There is also a charger inhibit harness with a fuse that might have failed. A qualified technician can jumper this harness to bypass and test.

If you have an off-board charger unplug it from the wall or unplug it from the charging port in the front of the VSI. If the chair runs in either case you have a bad charger.

You may also have a bad VSI controller which can be rebuilt or replaced. Start with the basic charger unplug tests and then work your way to the VSI controller. Hope this helps.
