Need Help Fast! Ballast Died!!!

So My Ballast Just Crapped Out. Ive been keeping it bearly running through the use of "jimmying" the chord and placing it in rediculous angles to get it to work. but i woke up this morning and its fucked. My question is, should I take it to an electronics store or buy a new one. i feel the only problem is with the imput as the cable has fried and a peice is missing and theres like plastic residue in the imput.
