Tovis-MTG-2901CN Monitor Died After Power Surge
« on: September 05, 2013, 10:30:30 am »
My 2005 Tovis-MTG-2901CN 19" died after a power surge from a thunderstorm. Pulled the flyback (suspecting it went open, fuse is good) and the schematics for the MCK-20A036 flyback here (http://poweronix.com/Files/MTG-1901CN-1301CN-Schematic.pdf) seem to be incorrect. I realize the PDF says 1901 not 2901 but its the only one I could find. Reason why I think it's incorrect is I tested across pins 8 and 10 on the flyback and got a short. Schematic also says it as 14 pins but I only see 13. I know it's not shorted because the chassis fuse is good. Where to go from here? A shorted flyback would most definitely blow the fuse correct?

power surge would have killed components in primary psu,guessing its a modern switch mode you should be looking at bridge rectifier and ntc,possibly any regulator ic
