Question

They told me it's a power supply. I just noticed, that we communicate on two postings. The part # you gave me is right. I even have a picture that I can e-mail to you. I hate to change it and find it was a mistake. Can the power supply be repaired? I'm not trying to be cheap, but I'm tired to be fixing new things. It seems to be happening more often nowadays. THIS TV IS 2 YRS OLD AND A FEW DAYS AGO I GO TO TURN IT ON AND NOTHING HAPPENS.....NO POWER I HAVE CHECKED THE FUSE...IT'S FINE. ANY SUGESTIONS
