Re: Sceptre32 MegMeet mp116 Solved

I recently had this power-supply board repaired.
When I first got it PFC transistor was blown Q2 (MDF13N50), fuse and resistor from mosfet to ground R42 (1 ohm). Replaced all of them and it didn't work. The problem was when you turn the tv on, back-light was flickering, it would power on, stay on for a second, then turn (back-light) off for 2 seconds and repeat. I thought capacitors were bad. Replaced them all. Still the same problem, then I saw that board was warped (probably form prolonged heating), I suspected some cold joints and resolder...
