LG 32LV3400 T-Con problem??
A customer brought a LGLV3400 32" LED tv to my workshop for repairs...not a model sold in my region(India).. getting hazy picture with venetian blindness effect. Is it a T-Con problem?? following is the t-con board on it
will it be possible to get circuit diagram of this?

Re: Viewsonic LCD VA1703wb
thanks budm... I think i have confused you. Came to say even when a good set of lamps are connected to the board, problem persists. I came to say it is NOT problem with lamps. It should be problem with the inverter board. Will upload photos little laterLeave a comment:

Re: Viewsonic LCD VA1703wb
oh thanks again budm... Is there a chance to eliminate the current sensing?? I have confirmed the lamps are ok by connecting different lamps.Leave a comment:

Viewsonic LCD VA1703wb
[B]Viewsonic LCD VA1703wb[/B] : opened one va1703wb model viewsonic monitor for the problem [B]'backlight turns off in 2 seconds'[/B]. Replaced all the capacitors still problem persists. It uses [B]MP1008ES[/B] in the inverter board. When I downloaded the diagram it says the inverter contains OZ series chip on it!! Can anyone suggest where is the current sensing / ovpt for MP1008ES chip and how can I disable the ovpt??[B]Viewsonic LCD VA1703wb[/B] : opened one va1703wb model viewsonic monitor for the problem [B]'backlight turns off in 2 seconds'[/B].
