Question about Samsung SP-R4232 42 in. Plasma HDTV

1 Answer

Samsung PS42S5hX - Bottom half of screen flashing black sometimes permanent, does not do this all the time.

Thanks for the solution recently sent, having read a few more problems I have tryed tapping the side of the TV and this removes and brings back the black lower part of the screen, could this mean that it is probably a loose connection/solder joint and would this be on one of the boards that was mentioned, either the Y main board or lower buffer board?

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.

Samsung HPR-5052X Plasma issues. Recently started

If the picture os goint to lines right from the midpoint downward then most likely you will have to replace the lower y-buffer board part number BN96-02027A. The board is mounted on the left side of the plasma panel when you take the back off. The upper y-buffer board sounds like it is failing as well and this was a very common issue on the older Samsung plasmas. The part number for it is BN96-02026A. Please take a moment and rate my answer. Thanks...

Bottom half of picture cuts out?

This is most likely a "cold" solder joint on one of the components, i.e. capacitor, inductor, ect. If you are handy with a solderiing iron and disassembly and more important reassembly, then you could reflow the cold joints. I hope this helps. Good luck :)

Top half of screen blacks out

Today, after speaking to the Sansui Manufacturer representative from Japan. He stated that all you need to do is to turn off the closed caption from the TV remote and not the DVR remote. Black screen can occur at the top half or the bottom half of the screen depending on how it was originally setup during installation. Try this and hopefully this fixes the problem.

This could be caused by the Y-main board or the lower buffer board going bad

Blue/black vertical line in the middle of screen

Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck
