The JB-199 player does not reacts on the front panel buttons pressing as well as on the remote control buttons.

If your JB-199 player front panel buttons stoped work as well as the remote control buttons, you need to check few things.

 

Step One. You have to go to the Windows desktop, make a right click on \”My Computer\”, then click on \”Properties\” -> \”Hardware\” -> \”Device Manager\”, and in the \”Ports (COM & LPT)\” item check, that 2 x \”Communication ports\” are present (COM1 & COM2). They a re also must be enabled. If one of them is missing, you have to turn it on in \”BIOS\”.

 

Step Two. If both communication ports are present in the \”Ports (COM & LPT)\” item of the \”Device Manager\”, you have to take the top cover off from the JB-199 and check the wires connection. Check the wires, marked on the attached pictures. They are must be connected.
