Question about Televison & Video

1 Answer

My plasma screen gets horizontal lines running through it, and sometimes the screen is split in half. It is fine when first turned on, but a few minutes later gets those wavy lines then the screen splits. Sometimes the lines are so bad you can't tell what you are looking at at all.

    If it is the system board is this something that can "fix" itself?  I ask because this is the second time this happened..the first time it just all of a sudden started working fine..now it's over a year later and the problem is back.

This problem is due to either a fualty system board which is quite common in the plasmas. If you have good wires and good connections, than that means the convergance is off and you may have to have new IC's installed.

    It will be difficult to replace without repair schematic, testing light, ohmmeter, voltmeter and knowledge of electronics repair. If you have the knowledge and the schematic and tools, it should be an intermidiate difficulty level.

    It sounds like it may be to loose capacitor or diode, mabey even a loose wire if the problem goes away and comes back. The only way is to test all the capacitors.

    :Look for any loose wires, capacitors, or loose solder joints.first.
    If nothing is found, I would have a tech look at it and perform further testing.

When you turn the TV on the screen splits in two,


it sounds like one of your buffer boards are going bad. these are the boards that help put the picture on the screen. there are 2 boards an upper and a lower board. if you remove one and turn the tv on you will get half a screen. see then if you get the lines. please leave rating after you check.

Screen Problem


hi....Your tv picture is managed by several boards, the two specific ones are the ysus and the xsus. The Y controlls the horizontal pixelation and the X the verticle, if you are having horizontal problems then its the Ysus thats faulty, on this particular set, the Ysus board has two accompaning buffers that are particularly troublesome. I've had more than one of these sets in the shop recently with the same ailment.Sounds like your buffers are starting to go out. The screen is split horizontally by the two long skinny buffers attatched to the Y main, if the bottom one has one leg in the grave you'll be getting a partially black screen or no picture at all. The colored lines running through the screen are more typical of a failing buffer. Are you interested in taking this set apart and putting a couple hundred into fixing it?  When buffers go they usually take the Y main too. Worse case scenario you're gonna be out about $350 dollars to fix it yourself. Best case, a ribbon is loose on the bottom buffer and with a dismantle you'll be able to connect it again..

thank u rate me!!

AKAI LCT2662N screen problems -distorted


that sounds like your LCD controller, since the LCD screen is so big, they will "split" the screen into 2 smaller screens, otherwise it would be so outrageously expensive to have one big massive lcd controller. Your lcd controller is most likely a two-in-one card though, meaning that there are 2 controllers on one board. You'll more than likely need a new controller card for your tv.

Horizontal lines obstructing the second half of the ti 83 calculator screen, anyone know repair tips?


I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.

Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.
