In the service manual it describes the beep codes. THese are used when no video is present to help in troubleshooting when you can not see the screen. Unfortunately, there are no codes with 4 beeps. Try to listen carefully for short beeps, pause, long beeps and get the sequence for more troubleshooting from the manual.
