I own a Samsung HL61a750 rear projection DLP tv, just got it fixed and the tech stated it was a voltage circuit doubler. What is this and what does it do? I was expecting a bad power supply, led driver or main board after researching the errors i was receiving. He charged me $315 to fix, did i get robbed?
