Re: LG RT42PZ45V standby ok no start

Seems I was a bit previous with this one. My friend put it back together after I got picture but that was only menus etc and no signal going around the screen. But when reconnected to input sources the screen shows what I think are electrical interference thin black stripes at about 30 degree angle to horizontal from right to left all down the screen and over the picture. Have checked and reset Va and Vs. Can hear slight buzzing near power inlet when signal being received from any source inc DVD but no buzz otherwise. Any thoughts??

Ahhh some success at last - very much like this pic with just more upward angle across the screen. The power board is made by another supplier to LG and no schematic but it is just overflowing with components. Three very big caps are 450v rating and other two which supply Vs Va are 250V and they all look OK. On the main board the set voltages are marked and adjacent are red lights which seem to indicate all ok too as check measured. Board also has about 5 green lights of which 3 remain on and two flash about each second.
