GS1501 Pantograms/Avance Control Panel LED

I have a 2014 GS1501 Embroidery machine that has never given me any issues until last month. The LED Control Panel quit. I've replaced the battery & tested the power switch, power supply, etc... all is well - the control panel screen nor any of the buttons work.
Besides for Coldesi (outrageous cost!!) I cannot find a replacement control panel anywhere online.
Anyone with experience know how to get one that's not thousands of dollars?
I'm located in Hardee County Florida (Central Florida)

Location: 
United States

Connector with red,black,brown,yellow wires.

If you check with an voltmeter between black(normally must be -minus) and red,brown,yellow,is any voltage ?
I will ask an friend of mine from China about panel.

The machine was produced by Ricoma,customer requested to be produced without RICOMA logo on identification plate,or panel.
