Question about Televison & Video
Hi, I Have a problem with vertical black lines appearing on my screen, when i turn the screen on it generally takes about 30mins before they appear, sometimes its one sometimes 2 & very rarely 3, if i leave the tv on, again normally it drops back to just the 1 line after a short period of time (if i'm really lucky they all go away), the lines are roughly an inch thick and keep changing places!! Any suggestions would be much appriciated! P.S: was reading a thread on AVForum and people having the same problem with a Hyundai model said it was a dry joint problem & could be fixed by a little soldering, could it be the same problem?
IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........
ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

I had a similar problem on a panasonic unit. It turned out to be a ribbon cable just above the affected area that had become loose during shipping. A tech came out and reseated it and it has been fine ever since.

Very likely same problem. I have a Hitachi that was up to 5 of those annoying lines. Found the AVForum thread and took it apart. (Figured might as well try!) Anyway, soldering and fixed...No more lines!

I had the same problem with my LG. It turned out that 2 PCB's needed to be replaced inside. It was an easy repair for thoes who know their way around electronics. It was the "Control Board" assembly, however your TV SHOULD be calibrated after the replacement of these PCB's. I have been unable to find a service manual to do the calibration myself and do not have the expensive equipment to do the calibration so I would suggest calling a certified calibration shop to do this part of the repair.

Yes, could be fixed by a little soldering but you need some electronic skills and cautions. remember that tv sets always remain charged with mortal voltages even after switched off.
