i have 6months old jvc stereo system, i encoutered with it this problem. Whenever i plugg in power it writes on the disply screen UPGRD DISC.It ejects the disc automatically even if i don"t press open butoon.it has even locked the radio and tape systems.I took it to technician near by who first told me the reading lens is dead, two days later tells me the IC is blown off what could be the exact problem?
