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: horizontal lines and colored snow

HI,
There are three likely causes for horizontal lines on your plasma TV.

1) A bad incoming signal. Do you see the lines on every channel, and from every source? If you play a DVD or videotape and the lines are still there, then that rules out your cable television or satellite box if you have one. However, if you find that the lines disappear when you play a DVD, I would contact the support desk for your cable or satellite provider.

2) A burn-in. This is caused by things like excessive use of video games or watching TV programs that have static (unchanging elements) like icons or scores or even lines. Have you tried using the built-in burn-in cleanup utility that is part of most Samsung plasma sets? Even if you suspect that the problem is not caused by burn-in i would recommend you try this just to see if it has an effect.

3) A problem with the electronics. Here you have to asnwer the following: is your set still under warranty? Most plasmas come with a one- or two-year warranty. If you paid for the set with certain types of credit cards, your warranty may be extended by a year or so: call your credit card.

If the set is still under warranty, immediately arrange for a repair and keep a record of all dates, names, phone numbers, and promises made. Don't accept any statement that five horizontal lines is "acceptable" to the maker; a pixel here or there may be excused but not a serious problem like yours.

Finally, if your set is NOT under warranty, consider carefully whether to make a repair or buy a new set. New set prices have dropped sharply, and the difference between a repair and a new set may not be significant. Of course, you can wait until the set fails.

thank you,
vijay

SOURCE: I have a Samsung Plasma 4252 and i have red horizontal lines.

I have the same problem on my set. I had a repair technician out today and they wanted to replace the circuit board that the buffers are connected to and the adjacent board that drives the buffers. If you remove the back panel the buffers that are in line with the distorted areas on the screen are running super hot. Estimated price with labor was $700.

Hello,

All plasma an lcd TV 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 resetting the connection will fix it, if the ribbon cable has been nicked there could be a severed connection. They an sometimes be fixed, but it is a pain. An yes I have done it, but 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.

Why my canon G12 present black display or horizontal lines overexposed?


It's common on the G12. This is the place fixing these: www.CamerasAndParts.com They have a specific service package for this $89, parts and labor come included, plus they do the internal fix so it doesn't keep occurring on the camera. They are the best place for help with the Canon Powershots. Best of luck with it.

I have a 2" black line at the top of the tv. And also smaller black lines across the middle of the tv.


Dear Jeff,
It seems like the Horizontal IC in your TV is dying. This and the Vertical IC is responsible for displaying images on your TV. (Look at your TV through your Phone Camera and you will see upward scrolling lines.This is the Horizontal IC in action.)
I would strongly advise you to get your TV repaired immediately.

Black screen with horizontal green lines


Hello yoyoxide.


from my experience can be something related with the video card. I recommend you the followig (Hardware diagnostics):

-Look for one of the discs that came with your computer, it should say (Drivers & utilities).
-Boot from the CD. If you don't know how to do it do the following:
1.Insert the Drivers&Utilities Disk.
2.Restart teh computer.
3. When you get the Dell logo, press F12
4.Select Boot from CD/CDRW-DVD (something like that).
-You will get a prompt to run the diagnosics.
-Just follow the wizard
-I recommend you to run diagnostics for everything.
-You will see if you have any problems with your hardware.

It seems that you have a pretty new laptop, so probably it's under warranty.
