No picture no sound. I had a tech come out and he said I needed a new main board so I ordered a replacement and installed it. But it still doing the same thing. Turn it on. The red light blinks three times then goes out and the screen is blank.

Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, there are several versions of this model using different engine/chassis. Is the replacement main board identically numbered as the old board?
