BTL 4920 Smart Magnet Therapy only shows sandglass and then goes back to the yellow power button.
I can make it to go to service screen and play with options, but it still doesnt go to the normal screen when restarted.
The support battery is intact. All electrolytic capacitors are intact.
Does anyone know what to do?
Perhaps someone has the most up to date software so I could upload it from USB?
Any service manuals?
Thanks in advance

If the power supply is ok, then
You need FW update.......
Contact BTL office in your country..
Otherwise,
Replace the masterboard.
