Black Lines on Plasma Hyundia HP4240

Hi, I wondered if you could help, i have a black line going from top to bottom of the screen on an intermittent basis, there is no real pattern to when this happens, if the televison is on for say 4hrs the the black line is there for 3hrs. I am wondering if this is now beyond econimical repair and i should just take the hit and buy a new one, i have looked at the various forums and some of the fixes and have to say that i am not that technically gifted to borrow some iron from a soldier......Please advise/help. Regards Gary

Black vertical line on p42w34p plasma


The plasma display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.

Hi, I have an Insignia 50 in plasma television that all of a sudden went to nothing but vertical lines, then popped a cuople of times and went black. Sound is still ok.Enybody have an answer for me as to...


this is a buffer issue.

do the line go through the menu if you display the menu when the lines are visible?

do the lines go from the top to the bottom of the screen or stop halfway there?

do the lines change colors?

if the lines go over the menu and all the way down to the bottom of the screen, then its a buffer issue, top and bottom buffer.

hopefully it's just halfway then you only have to replace the top buffer, less money to spend.

Hitachi 50" hd TV displaying black lines on screen


Sounds like your YBL-Y Buffer lower board is going out. There are 3 boards here. The Y buffer upper which controls the top half of the display, The Y buffer lower controls the bottom half and the Y-SUS main control those two boards. They work in unison. Usually if one goes out you have to replace all. You can also get lucky and just repalce the YBL and all may be well. Now if they are vertical lines up and down the OSD-On screen display, then this is indicitive on dry solder joints on the D, G E, F boards. Hope this helps...

Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.

Black lines on plasma


The matrix controler or the matrix drive area is failing. The fix is to change the proper circuit boards, and then do the factory setup to match the board is necessary. In the worse case, it may be the display screen itself that has a failure occuring.

You will have to bring the set for factory service to have the work done. If the set is out of warranty, it may be expensive to service.
