Pg-fp5 programmer self-Test fails

Hi forum,

I've got a pg-fp5 programmer. Unfortunately, when I turn it on, it doesn't show anything on the LCD. When I connect it to pc with usb, it's recognized and I can do all the functions such as changing hex file and so on. But in self-Test, power supply test fails. Could you please tell how I can fix it? I know it is very old programmer and is not supported by Renesas anymore. Thanks in advance
