Re: HP DV6 issue ?
In my motherboard, that have a bad GPU chip, I read in diode mode: 0.99 - 1 on pad 1 (see image) and 0.001 on pad 2. since after you have removed PL12 , the short remain, probably one of these mosfet (pq25-24-60-61) are in short or PU13 is damaged. To investigate, remove one by one these mosfets.
Start from PQ25 and repeat the reading in diode mode where you have reading 0.006 V (pad 1 on the pictures) post result. If the short remain remove PQ24 if the short remain remove PQ60 if the short remain remove PQ61 At this point the short should be disappears and we can consider to replace mosfet or remove all circuit related VGA power.
