Tell the page what broke. It flags anything unsafe, reads error codes and works out how much a repair is worth at this age - free. Then get a yes/no flowchart to walk with the thing in front of you, cheapest and safest checks first, and a straight call: fix it yourself, call a pro, replace it, or stop.
