Agree with vid, you have to count the flashes on the MPU board. Battery damage is often bad on these boards. If your not getting any flashes it could be anything from lack of power, bad chips, bad chip sockets, bad reset sections, broken traces, bad cables, or a combination of all of the above. If you are not willing to work on it yourself it will probably be too expensive to get it fixed to be worth it. If you are willing to work on it yourself then I would take it at a good price. I just bought 2 pins using almost the same boards and neither one would boot. I got a good package deal on them and got them booting. But I had to repair broken traces, bad ribbon cables, bad chip sockets, bad chips and bad power cables before they would boot. Once I got them booting I had to fix switch problems and lamp problems. If I hired someone to fix it I'm sure the price would have been way more than they are worth. But doing the work myself made it a good deal. If you consider all the time I put in then I probably got paid a couple cents an hour but I had fun and it was worth it to me. Again if I hired someone I'm sure I would have lost a lot of money and it would be much cheaper to just buy them in good condition. So if your willing to learn and do the work yourself you can get a really good deal and have fun learning how to fix it. But if you are going to pay someone to fix then I would pass on them and buy one in good condition.
