Re: VESTEL 17IPS20 in 48" Tosh LED, dead...

Hi everybody! Been around the forum for awhile (very helpul, thanks ) but this is my first post. I think I have the same fault that Alastair. The set is a 40" Vestel with 17IPS20 Psu. No fuse blown, no shorted transistors, no shorted diodes but no out voltage . I only have a pulsating voltage on the secondary diodes that goes this way:

With main board connected: Fast pulse, 11V-3V
With mainboard disconnected:: 11.8V then slowly falling down to 7V, then up again,the down,then up...

You can...
