MY MG5170 has B200 error. I have tried many things on the internet including the replaced printhead(2-->1). it is an old printhead(1) that yellow cloged up and I replaced with the other one(2). and 3days pass it comes back on again. I have bought a new printhead but refuse to get it on because I thing the logic board is gone. Any suggestion without going to service center? Trash this and buy a new one? or Just point out the thing that could gone wrong at this state? Thank you in advance.
