Needs a service adjustment that is a procedure that the service person does when they service your TV. This TV the sequence of steps and taking data sometimes takes hours. It involves unplugging the TV and hitting keys in sequence, usually Mute, Action, and the ARROW keys. Once the service adjustment is done the TV be comes fine tuned.

    Check and see if the channel is digital or analog. You may have to go to the original format analog. Then again because of the change in digital signaling may have got upgraded and need reset to it.

How long is a piece of string?

There are 2 boards called sustain boards inside the set. Either one of them or both could be the culprit. Unless you have electronic skill, the right tools and know how to retune the set, I would siuggest this is not a DIY job. Some willsay it is just a matter of unplugging the boards and replacing them, howver that is a short lived fix in a majority of the cases i read on here.

Yes it does work for a while, then other problems arise.. conergence drops out, power fails and a myriad of other things happen that would normally be measured and checked by a good repair technician. It ends up costing 2-3 times more than if it was done professionally. The decision is yours, but i can only advise you NOT to.

Thanks for using FIXYA

Horizontal lines plasma screen


The details you provided here is not enough to provide a solution to this problem. Check http://electronicshelponline.blogspot.com/ This link. Pull up older posts there. Defective screen shots to plasma TVs are given. Compare them with your TV, and try to understand the fault. Most plasma screens will have similar circuit configuration, irrespective of brands and models. The only difference will be the number of circuit boards it contains according to its screen size.

Plasma TV has a black uneven splotch in the middle of the screen


hmmm. sounds like the screen might be damaged. You might have to get a new one. But before you do that I would try leaving it off for a while maybe a few hours or so and see if that helps.

I have a 5 yr old Samsung HP-R5012 Plasma Display Television. A display model. Last night, horizontal lines appeared, then, the top half of the screen went black, with color pink and blue surrounding the...


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.

They didn't fix the issue this last time. The most common failure in these models is the upper and lower Y buffer boards. There are updated versions and both must be replaced as a pair. The part numbers are as follows: BN96-03361A for upper Y board and BN96-03362A for the lower Y board. Please take a few moments to rate my answer. Thanks...

42 sony wega plama veritcal line


The PDP ( plasma display panel) is defect.You can look for badly soldered SMD resistors on the COF panels wich are located at the bottom of the screen.
Beware,the flatcables wich the resistors are located on are verry fragile!

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

1/2 screen blacked out


There is a couple of problems that will cause this symptom. The lower y-buffer board, y-sustain board, or the z/x-sustain board, on rare occasions the power supply. Most manufacturers tech support recommend replacing the buffer and the sustain boards, because there is no easy to isolate the problem. The easiest way is to swap boards till you find which one is bad, and this gets expensive. The buffers range from $75 and up, and the sustaines from $250 up to $400 each.
