R7750 and r7751 are both good, also which resistors are the pull ups, sorry for being an idiot. computer was liquid damaged, but looks as though someone ultrasoniced it already

I have an 820-4924 with no backlight, computer does get an image backlight is just not present. im getting the 12.5v all the way up to Q7700 but not after. No short to ground after the transistor .901 in diode mode both r7702 and r7701 are reading correct resistance also I am getting 5v on pin 5...

for some reason im thinking not all the balls on the chip melted, cuz i fluxed it up and just heated the hell out of it and it kind flowed a little bit into place, now its working fine, thanks for the help guys

all resistors reading under 1 ohm, all measurements were done with the cable plugged in

isen1 : .641 isen2: OL isen3: OL isen4 OL isen5: OL isen6: OL

okay so now i put a new chip on, and the backlight is flickering, still only the half of the screen though

im waiting on some more chips from louis, i used my last one that i just took off

ill solder on a different chip when i get home i have no idea if the displays good or not and dont have a test screen, thank you

So I have a 3437 board that i replaced the led driver on, and now i have backlight, but only half the backlight is working, one half of the screen is normal brightness but the other half is darker, is this a bad led strip or did i solder on the chip incorrectly

looks like I bought them from L2 computer in september of last year

I pulled an isl from a donor board, for some reason the new ones from the spool didnt work but that one did, computer sees the battery now, thanks for the help guys

pulled the isl again shorts gone again.... not sure what im doing wrong here

now i have a 1ohm short to ground on the same line again

when I put the isl back on it wasnt flat to the board, seems to be all fixed

okay so new problem, now when i plug in the charger it turns on, but then shuts back off about 3 seconds later and stays off

removed the isl short is gone

I cant see any liquid damage at all

wasnt the battery, ill pull u7100

d7050 looks perfect the SCL data line has a 1 ohm resistance to ground

I get 1.5 mv on SCL, SDA jumps around a lot. 2.5 ohms on R7151 .4 ohms on R7152 10 ohms on R7121 10 ohms on 7122, the board looks absolutely fine, no evidence of liquid anywhere
