I purchased LC102, tooked laptop PS (18V) and unit powers ON without any problems. As unit stays somewhere on dirt, behind foil, which is in front of display i decided to remove front and cleaned.
I did this and at the same time i found also that that 4 connectors, which have wires only pressed in...were ...hmm...not the best as some wires just fall out, so i replaced all 4. Must note, that i replaced wire by wire so no posibility to mix them between. After put all together unit not powers on. I didn't looked much just checked if voltage came to 317 and yes...on IN is 18V and on OUT is 14V.
I said before imstarting to invent warmeater will ask specialists here who knows well some well known issues with this unit...so guys...is there something which could be problem?
I have all documentations...also all schematic combined together...so i already prepared myself for the worse:)
Thank yoiu.

if i recall theses connectors are crimped, if one or many wires are not fully pushed into the connector ....
you need the proper tool not just an screwdriver trick to push the wires inside ...
