Re: Samsung 46" LCD LN46A750 colored vertical lines no image



Seeing that you replaced so much of the tv without success in fixing it, seems almost not worth the effort seeing the drop in price of TVs these days. Figuring that even if you we did get them working again it would be apt to fail again in the next 2-3 years with the pos quality in manufacturing they put into these things. Cost and effort start outweighing the benefits.

The only saving grace in this industry is the falling price of technology, I recall back in 2003 when a good 42 plasma...

That's pretty much what I've heard about their TVs from 2006-10, not sure if they've improved quality since based on the lawsuits. That being said if there's any easy enough fix to revive this tv for a few more years I'm game, since i did get it for free

Is there a way I can test and isolate the TCON vs power supply knowing this info? I read the SMD fuses on the TCON could be a problem too. I was thinking about bridging the F1 fuse to see if that would help, then bridge the F2 fuse.Re: Samsung 46" LCD LN46A750 colored vertical lines...

Hi All, 1st post. Got a TV from a friend which went bad. It has colored vertical lines/bands running down it on power up. Seems to power up fine with no problem however.

I took it apart and found that out when the TV is on and I pop one of the ribbon cables attached to the TCON out jiggle it around a bit and pop it back in that the screen is working perfectly and is stable for as long as the TV is powered up.

As soon as I turn it off and power it back up the vertical lines are back. Good thing I know the panel is good, seems like the ribbon cables are fine...
