Re: westinghouse LVM-47w1

no around 1200v - 1600v DC to power the tubes

only with a known working inverter

Re: westinghouse LVM-47w1

the ribbon that i unplug to make the tv stay on, goes across to the master board, i can unplug either and the TV will power on, (i tested for continuity)

also when i test for voltage on the copper pads on the slave board i get nothing, when i test on the master board the TV shuts off ?? sounds like a bad slave board ?

Did. You check the fuse on the slave inverter ?

Re: westinghouse LVM-47w1

might work,can you disconnect slave and vise versa,one at a time,and see if mainboard,and psu still power up? and remain so,something is dragging everything down on them inverters
im leaning towards faulty tubes now

Re: westinghouse LVM-47w1

i moved the master inverter board to the location of the slave plugged in all the tubes etc, it powered right up and remained on, so the fault has to be in the slave board, i re examined it everything looks fine so one of the components must be shorting out on the inside

Re: westinghouse LVM-47w1

update i ordered an inverter board and had the same result turns out while plugged in when i move this (see pic) ribbon around it will either turn on the rest of the tubes and stay on, leave right side tubes off and stay on or do what it was originally doing lights off and a creek (audible noise)

so im taking a guess that the ribbon is bad ? but i cant seem to find that part anywhere

any thoughts on locating one or what the problem might actually be ?

thanks
