Dont know about the LEDs on the CPU.

But the "Trans mode" on the OP37 means that it is waiting for a program to be downloaded. It is also possible that the program is (was ?) on a flash card, and the card isnt properly seated.
In certain cases you had to abort the Transfer mode by pressing [ESC], only then would the program load.
If there is no flash card, and [ESC] does not help, then there is no program in the OP37 !

Dear Jesper

Esc key is fully damaged condition it will not work, instead of that can we use computer key board. Thanking you for your immediate reply

I am not sure. I know OP27 but not OP37.
If there is a keyboard port, then do try to connect a normal keyboard.
