[TV] Re: Insigna INP4219 plasma does not power on
Peggs , I have check the resistance to ground at P5 connector (you had suggested connector PS, I can't find it).
Resistance looks shorted to ground. I have check VS pin to Grnd.
But the fuse is good , removing the fuse , tv stays on (blue led) but nothing .
Putting the fuse back , I can hear a faint buzz from power supply , and led return to red , and cycle again.
Thus removing the big connector going to Ysus , no more faint buzz of the power supply.
By the way ,this Insignia has all LG boards and stuff inside.
Thanks
