Title: Samsung PN50A450 Plasma
Post by: topfli8979 on February 24, 2013,16:22:38

New here, picked a 50 samsung plasma PN50A450.  Originally would not power up just cycle from start then shut off imediately.  Found some shorted fet's on y main, purchased new y main.  Powers on, stays on. Just no picture, I do have sound.
