Needs either a power supply board replaced or a home board replaced. Not sure which one has gone bad but they cost, US and not CHINA, btwen 70-90 dollars each. Odds are almost certain that it is an either or board.
I had it for years and it has a really beautiful look and picture.
Very heavy, about 80 lbs.
You will need 2 stronger young men, not your son or wife, to be able to carry and move it.
It is on the second floor and after that it is just a short walk to the curb.
It is big, so don't bring your compact car to try and fit it into.
