Re: LG Flatron L17NT-A no power
could it be that i dont have it hooked up to the screen?
and i also dont have the back lights hooked up.
i do have a question shouldnt i be getting some kind of power out of the back light terminals?
i also looked at the thread you sent to me and im not sure what you want me to see?
thank you anyway for your help.

Re: LG Flatron L17NT-A no power
Ok Plainbill,
if i knew what i was doing i wouldn't be on here..:-) <bk>
i will try to be more precise from here on out <bk>
i crossed the filter @ junction C101 and got 160.8 dcv <bk>
@ connector CW201 pin6 =5 dcv. and pin7= 5 dcv , pin10=13.78 ,pin 11=13.78. <bk>
8pin ic @ U101 i jumped pin 1 and 5 and got 115 dcv. <bk>
thats how i determined the power board was in good shape. <bk>
now for the logic board the parts you circled.<bk>
U202= 3 TERMINAL...Last edited by fsearcy2; 03-30-2010, 08:35 PM.

Re: LG Flatron L17NT-A no power
yeah i pulled the cards out and disconnected the cables but that was after i did all of my testing to see if the power supply was working i wanted to check the boards out really well to see if i could notice anything that didnt look right.

Re: LG Flatron L17NT-A no power
Thanks Plainbill i found this thread then since it was the same exact board i followed the directions you gave in the post to Elmojoe and i have power at the points you pointed out so i didn't see anything else because that fixed his problem but not mine so i need some education. so here is a couple of pic's to get us started....
