I have a faulty samsung LE32R72BX/XEC.Horizontal lines across the screen in both the menu and the signal mode for a while, so reducing the interference in menu mode but still in signal mode. I have checked the power supply ok even disconnected the vo controller board and backlight lights up normally sending picture of it!

anyone know of any common faults
thanks

Hakan

Hi,
This is common problem in Samsungs, main board faulty (poor BGA soldering on pcb)...

Thanks for info!

Is it possible to solder again? or have to buy a new mainboard?
