Hello,
tv model LG 42lh4000
mainboard EAX60686902 (0)
t-con EAX58017201 (9)
psu model EAX55357701/32 (rev 1.3)
The picture got dark from top right to bottom left while using and then it didn't show anything again. I can turn it on and the back light comes up, sound works, but no picture, OSD, ...
There's a soft hum (perhaps electric arc sound) around the two LIF42-inverters on the psu, but perhaps that's normal.
I tried to follow some material from LG Training Center for the 42LH50, but the 42LH4000 has some differences, e.g. there's no fuse or led on the t-con board.
Thanks for your help!
