Title: 42LG5010 sound no picture.
Post by: pan on April 20, 2011,12:53:40

Hi
I’ve Located the fault on the master inverter panel (VIT71053.50 Rev3).
F1 is o/c (no 24 volts) it’s a SMD with 20 written on the top.
When I bridge the device the backlight / picture comes on and all seems fine.
Not sure what the value is (I’ve not got a diagram).
Any help much appreciated.

Thanks
Pan

Hi

ignore my last post (this is the right forum).
Update as I might have not made myself clear, Fuse F1 which is o/c the SMD has 20 written on its top I think it’s a 2 amp, I temporally bridged it with a 2 amp wickman it worked.
Can any of you guys help with any info.
Thanks
Pan
