Atv display

My guess would be that there is some start-up sequence that should happen automatically when the ignition is turned on. That start-up sequence stops working due to age, and then you manually perform the start-up sequence with the fuse.

It's possible that there is an electrolytic capacitor that is too old that affects the start-up timing, that could be replaced.

Also there is no end of different issues that can be caused by poor battery states and poor connections. I wouldn't be surprised if the problem is a symptom of a weak battery or a bad connection somewhere.

There are lots of guesses in what I've just written. l would try to find a circuit diagram of the display unit before going any further. Also if it's as common a problem as the video suggests, there may be a fix if you search for it.

Thanks yes battery is good. I have 12 volts going to the display and 14 volts when running. So all power to the display is good. And has a brand new battery. I have been looking for a fix There are a few companies that will fix it for you but I like to do things myself. I have not been able to find the schematic of the board yet. Just the schematic of the whole machine so it does not really break the display down.
