anyone have a link for this manual?tried the usual places but no joy,i need to check the control lines(BL_ON) for there correct voltages that goes from main board to the master inverter (also there is a slave inverter),bit more info,this set when plugged in powerd on had no backlight(not even a flash),sound working,menu visable with flash light,further testing found a blown smd fuse(0.25A) (prefixed "d")on the master inverter,no other blown fuses on master or slave,all duel fets tested good for shorts,regulators tested good,24v to inverters good,inverter transformer secondarys and primarys all around 4kohm on secondarys,good,,all psu voltages good,removed the blown smd 0.25A fuse,checked for short across the fuse pads ,no short,replaced with the same(new) fuse,powering back on the set changed the symptoms,this time the backlights flashed on then off,im pretty certain there is a problem with the master inverter,but want to check wether the control lines have correct voltages,oh,and ive checked the ccfls one by one with a known good working ccfl (20 in#) and set still displays the same symptom,1 sec to black.still cant put up any pics as i still havent got my sodding camera yet !!

Re: toshiba 42wlt68
^Please don't post like that, it makes it very hard to read - break it up where possible.
Here's a manual for the 32WLG66 which is a similar TV to the 42WLT68. I also worked on a 42WLT66 but that's long gone.

I'll search around for my 32WLT66 manual I downloaded at some point - may upload that too.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
