    I am having the same problem. I don't even have to turn it on. As soon as it's plugged in, popping noise comes from the speakers and the blue power light flashes. Please help!!!!

    Its not that expensive tard. I see why your still an apprentice. Its a convergence board issue. The stk's were $50.00 on ebay and the resistors were under $3.00. Better yet, if I didn't want to solder them in and replace them myself, the convergence board costs around $150 new. Instead of posting something as stupid as that comment next time post something helpful. That is what this site was intended to be, a help forum for people with technical problems. If anyone has issues with this model tv email me at Ill be glad to help anyway I can.
