Hi this lg has a rediculously small 16 pin ic on mainboard cooking
causing brief flash of sby led then dead its the one next to a coil 2r2
reference ic2403 i cant make it out looks like:
5419
0rAA
A36X
this tv had bad b/l leds and i replaced all the strips with new
they tested fine with led tester ,ifound the b/l controller ic s/c bl0202b and q803 s/c these were replaced but leds just flashed on for one second .
to save time (big mistake) i ordered replacement psu from e bay
when fitted it caused the mainboard problem grrr!
now even my original psu wont start up
ive tried to find cct for main board i can only find psu cct
if someone can help me identify the ic or suggest why the rogue psu has caused the problem it would be a great help
the rogue psu is:EAX65423801(2.1)REV 2.0
the original psu is:EAX65423801(2.2)REV 2.1
