Re: hisense ltdn46v68us service manual

ON/OFF is probably PSON on this set. Test all voltages along the pins.

psu - main = actual

gnd - gnd
gnd - gnd
stb - on/off = 2.2
5v - 5v = 5.2
5v - 5v = 5.2
12v - 12v= 11.86
12v - 12v= 11.86
gnd - gnd
br1 - dimm =0
sw - bl = 0.4
gnd - gnd
gnd - gnd
5vm - 5vin

Didn't see them in photo initially. Looks like PSU is good main board is bad.

Re: hisense ltdn46v68us service manual

any idea what? these tv's are crap!
off topic! best way to trace a lifted component or broken trace? the other main i have is quirky! could tap it an it would live! soldered everywhere i could an still does same!
