I have a 50" Samsung PN50A550 plasma that i have been riding for a long time now. I have had it fixed several times and once again it has gone out. Main board again I believe. Is this set worth keeping? or should I just let it die and get a new TV? Fixing it will cost around $100 but I've already repaired this thing like 4 times. This is my bedroom TV so I'm not spending $$ to get a new one. Less than $500.
