    My Toshiba 27D46 "flatlines" too! The Picture disappears leaving only the sound and a thin white line across the screen. The TV is two years only old.. The manual said it was a weak cable signal.

    The cable guy came and said the signal was strong. No help! For a while I could fix it temporarily by turning it off and on again, but now it's completely gone. Anyone know what to do? Puzzled.

Check its horizontal output section circuit for any loose solder terminals. Resolder all suspected solder terminals by applying little more fresh solder. Replace the horizontal output transistor. If this transistor have some leak, it will overheat within minutes will shut down the picture.

When I turn on the TV with the remote or on the front, it comes on for a second and then shuts off. I was able to keep it on once, and all I got was a horizontal white and colored line across the TV, but...


horizontal lines indicates that the vertical section is most likely the defect..a defective deflection yoke could cause this and eventually damage the vertical output ic causing an overloading in the power supply then can caused to shut down

Unit has sound, no vertical deflection. caps and output ic ok. have b+ to output. nothing at pin 2 of output ic.


If there's an audio,,it might be the defective Vertical IC...but check first if there's 24v-26vdc supply coming from FBT going to Vcc of Vertical IC.

If there's no Audio,and only white horizontal line in the screen,check the Vertical out of Jungle IC.

Good luck!

Intense white & coloured horizontal line on black background on startup


I wouldn't attempt as the capacitors on a tv store around 25000 volts this is more than enough to kill you and they keep there charge even when the tv is off. Either take it to a repair shop or put that money towards buying a new tv - Do not even attempt to open the tv. (It sounds like maybe a tube has gone or the electromagnet that makes the beam move vertically is gone.

Pulling in from the sides usually results from poor regulation or width problems related to the horizontal circiut. These are not usually repaireable by a non technician.

Intermittent loss of picture


You'll have to locate the vertical output IC which should be mounted onto a heatsink, then take out a good magnifier under the printed circuit board and examine the solder connections on the pins of that IC and resolder the ones that are cracked.
