Re: Toshiba tv problem
This looks like a problem either with the powers supply to the video signal processor and with thr power supply to the horizontal section (lack of complete horizontal deflection. This was caused by the voltage and current spikes of the power coming back on rapidly. Now to fix this problem involves coming into contact with hazardous voltages, I would suggest that you not attempt this repair on your own if you do not have a background in electronics. Please take this set to a qualified electronics repair shop

hi all .ive had the same problem,a thick black line down
screen.sometimes it flickers from top to bottom and other permantly in
view.but i have solved it.forget your ic boards and taking apart tv.have
you got either a ps3 or wii connected to tv.if so unplug power lead
from socket and relocate in seperate socket.make sure the lead is
completely free of any other leads and you might just find this works.i
think the power lead creates some sort of frequency that the tv picks up
.good luck hope it works
Most likely there are electrolytic capacitors in the power supply, video path, and scan amplifiers that are starting to fail from age. This is common in many of these sets. In consideration of the age of the set, this may not be worth having it serviced.
I have same problem. Toshiba 42' hl196 purchased 4/07 line appeared 1 year and 9 months researched on Toshiba thread. Bad LCD screen. Repair cost more than tv-have to replace lcd screen. I didn't get the extended warranty. If still under warranty get hold of toshiba. Lot of people having same problem. Should get aclass action lawsuit started selling defective LCD screens.
