I own a Mitsubishi HD 1080 series HD TV;

I own a Mitsubishi HD 1080 series HD TV; MODEL#VS-50111. Recently the TV shut itself off after a few minutes of operation. I unplugged it and after a few hours, plugged it in and it came on for about 5 minutes then shut off again. I ran the Diagnostic check and came up with a error code of 2-3. Through other postings this error code should be either a Horizontal Deflection failure or an error with the Deflection protect. Is this a major repair/worth fixing? Love this TV and it's only 5 years old. Thanks
