Phillips 42" plasma42pf5321d-35

Question

problem started by the tv taking forever to come on - then got 4 blinking red led lights - was told to download software upgrade - got this done - sometimes it will work after unplugging and plugging back in but still takes forever to come on - after downloading software dont get the led lights but comes on about 1 out 10 tries - Is it even worth spending the money to fix? It is only 2 years old but dont want the same problem in another week / month
