The protect message indicates that the output section has a problem. The protection state prevents further damage. If you have no experience in electronics repair, any service shop should be able to help. If the output transistors have failed, figure on $8 for each one (will need at least 2). Supporting part may be needed as well so the total parts cost will probably run between $25-$35. Add in your local labor rate for the total repair cost.
