No there is no pattern to the blinking and the power light is the only light that blinks. the only other thing it dose is change color
I understand.Ok, so what's causing this? Things like this can be caused by a couple different things. The power supply board is the usual suspect here. More specifically, this model is actually pretty well known for having defective capacitors on the power supply which can cause this exact issue. However, the main board and the LCD panel (the screen) could also be causing this. The power supply and the main board would normally be cost effective to repair, and these are the most common issues. The panel would be far too expensive to consider replacing but that would also be much more rare, so the odds are on your side. Again, though, we won't know for sure until the technician gets inside to have a closer look.
This is definitely reparable. It will just boil down to cost, so the real question is: Will this be cost effective? The answer is... probably. The good news is that some hands on diagnostics wouldn't run you more than $50-$75 (in my area) and most of that would be put toward the repair labor should you decide to have it repaired.
If you'd like, feel free to post back here with the technician's findings and the repair estimate. I'd be happy to let you know what I think. A typical repair bill here can vary, but would usually range $250-$450 for the power supply or main board. Again, the panel would be cost prohibitive.
