SOURCE: vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

SOURCE: Vertical Line started on left side of HDTV, and now

This problem is down to the actual LCD or plasma screen, if this shows as the screen warms up and stays on then the screen will need to be replaced, you should go back to your retailer (not manufacturer) and report this problem, depending on the store and how long you have had the tv, the tv can be replaced for a like for like tv at store as this is not a cheap standard repair.

Vertical and horizontal lines on screen


Check all connections that goes to panel from T'Con board for any loose connections. Re-seat them once and check. If the fault still persists, contact the authorized service center. T'Con as well as panel should be suspected. If you wish to get some idea about these kind of faults to LCD TVs, check this link. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

Check and replace all electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them to replace. Replace all at one time. The fault you describes here is technically known as 'vertical retrace lines'. Visit the site named 'Electro-help' for more details. Click this link.

The single horizontal line in the center indicates a problem with the vertical circuit. WIthout the make and model of your set, there is little I can do. In most sets, there is a vertical IC which is a small flat IC attached to a heatsink with around 9-11 pins. Resolder those pins. If that does not resolve the problem, replace the IC and report your results here. If you post the make and model, I'll be able to provide additional details,

Ps 27123 have sound, tuning etc only small horizontal color band


Hello bdedrick708,

If what you are trying to say is that you have a 1/4 inch horizontal line across your screen, this means that something in your vertical deflection circuit has failed. This could be the vertical oscillator, the vertical output processor, the vertical coupling capacitor, or the vertical section of the yoke transformer.

If what you are talking about is a vertical line from top to bottom then you are possibly talking about a failed horizontal section of the yoke transformer.

Why so little about the horizontal section of the yoke? That is because if the horizontal section fails completely then you would lose high voltage and no line would be present because you would not have raster (screen light).

In any even check the yoke transformer first. Then work back from there.

I hope this helps,

Thank you,
