Panasonic PT-47WXC43G TV, Turns on but I get 5 blinking lights

I own a Panasonic PT-47WXC43G Rear Projection TV that is around 5 years old.

Around 6-8 months ago I had to get it fixed for a convergence problem. After that it was running just fine up until just recently. When I went to turn the TV on the other day the TV sounded as if it was turning on but then I started to hear a clicking sound for a few seconds and then it stopped. The led power light blinks 5 times then pauses and blinks 5 more times, and so on, this continues on until I unplug the TV from the outlet.

I would just like to know if this problem is fixable, and if so how.

Any help would be most appreciated. Thanks in advance.
