SOURCE: how do I fix bad static?
Yes,loud static usually comes from bad isolation of sound signal path so it's probably a frayed cable or a loose jack. Or if you're unlucky some parts inside have failed.

The LED normally blinks--indicates the digital/main board is powered up.
Look for other fuses----Boards for these are rather expensive, maybe too expensive.
Google the model number with the word boards or parts after it to research it.
