Ravenheat pcb

[mickyyoungplumb]

I had a Raven Heat that when turned on the red temperature light would flash red. o manual so I rang technical. I by passed the overheat stat, still done it, I by passed the flow switch, still done it. So I was informed it was the board.

So I have replaced the board. The red light has stopped flashing but when I switch the boiler on the only light that comes on is a green light near the timer display. The main power on button to the left does not come on??
