I should've worded that last question differently, because everything
is reparable... it's really just a matter of cost, and this might
be cost effective to have repaired.
I can tell you it's definitely not the fuse. If it were, that red LED wouldn't illuminate. That being said, you either have a faulty power supply board, or a faulty main board. Either one of these could cause this, and both are replaceable.
If you can track down a multimeter and know how to use it to measure
live circuits, let me know and I'll help you narrow this down. Otherwise, you'll need to have a technician run some diagnostics to pinpoint this. The good news is that it's probably the power board (more likely than the main board), and the power board is inexpensive... about $65. The main board is about $165.
If you need help finding a repairman, just give me your zip code.
