My printer's display shows an arrow only...means it's not warming up.

Hi, I have HP Laserjet All in One 3055 model. (Almost 10-12 year old)

My printer is not starting..the display panel shows only one arrow only (warming up process)..previously arrows were keep growing and then printer starts working in 1 minute.

I doubt that formatted board is faulty…..however formatter board was replaced 4 months back with an old working formatter board.

Can any one advise?
