Thanks for your replies. Firstly the Majestic would not power up and no pilot light was on. It is the overhead tv in the salon and not the one down in the cabin and is 7 years old and rarely used in the past, which is a bit frustrating. Power is on at the dc cable to it. We took the back off the unit, looking for a fuse but nothing seemed replaceable, then I checked with Port Boathouse the Ranger dealer on Vancouver Island and was told that they have replaced several of these tvs which do not get very good ratings in reviews.
I am on the boat at present and we just took a small regular 18" tv from home, hooked up an Amazon Firestick and get Netflix, Amazon Prime etc. Set it up on the chart table plugged it in under the dinette table and we are in business for now.
Port Boathouse recommended a 19" Jensen (JTV19DC 19' Led TV, 12Vdc) which has a dc input plug and would likely work just fine but the cost is $300CAN so quite a bit more than a 110volt regular tv would be. I am undecided whether to just use a 110v and store it away when not in use or just get the Jensen.
