    I have a 42" Samsung Plasma, less than 2 years old. This black vertical line in the middle right about 4-5" wide showed up. It's always there, the only change that I see with it is that after a few minutes with the TV on a thin red line will appear inside the black one. I've read that it could have something to do with the address board but I don't have no clue what that means. Has anyone had this issue resolved and is it costly?

    i have the sony bravia 42"(?). black vertical line appears at the right edge of where the "normal" screen view meets the blank portion of the full screen. i only see the black vertical line when i use the full or wide screen mode. is there a cure for this?

    My screen has a vertical arched black line to the right of the middle with sometimes smaller lighter appearing corresponding lines beside it. You can't see it on all pictures but it looks like a tornado coming out of the sky on pictures with a big portion of sky. The line looks "burnt into" the screen and is not on the surface. Help, its only 16 months old, out of warranty of course. Is it cheaper to try to fix or buy another?

    Same problem with the vertical black line just to the right of middle on screen. Comes and goes with no apparent rhyme or reason.

All plasma an lcd tvs have boards that control vertical and horizontal output to their respective areas. They are connected to the screen by ribbon cables. If one of these boards fails all together, has a failed chip, a bad connection, or a bad ground somewhere it will result in a black line in the area of that board. A bad ribbon cable connection on the bottom will result in a vertical black bar though the screen. Many times reseating the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They can sometimes be fixed, but it is a pain. An yes I have done it, and the bar is gone. The same will happen if the chip that outputs to that area opens. The connectors are the first place to look paying close attention to the cable, they are extremely delicate so great care must be taken if you decide to tinker with em, the usually have lift locks that release them, but it is very easy to wreck em. Good luck.

If it is a single line top to bottom?? sounds like a bad panel. the reason is if it were a buffer module it would run only half way. this is a no repair problem as panels cost more than the plasma. also this is common on a plasma. 3-5 years.

If audio is OK, the fault is with its backlight section. If audio too is absent, the fault is with its digital main board. If you wish to get more details visit the site linked here. Pull up older posts.

Sansui sv29281 has a top foldover. I have replaced a faulty 1uf electrolytic cap in the vertical circuit but still have a problem.


Check and replace all the electrolytic capacitors at the vertical scan output section circuit at one time. Check the all the solder terminals to the vertical scan output IC for loose soldering.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electro-medical.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have sound but no picture on my tv


This is a popular question. Most of the time you either need to make sure all connections are not loose or just need to turn off your tv and receiver and unplug. Wait for 1 minute then reboot.
I recommend this short video as it walks you through some diagnostics for other possible problems.
