Question about Televison & Video

2 Answers

I have a 46' Polariod flat screen purchased from Walmart about 4 years ago. It started having picture issues in the upper right hand corner about 6 months ago. It appeared like the picture was zoomed in compared to the rest of the screen. It corrected itself the longer the TV was on. It has now progressed to being a dark hazy vertical line in the center of the screen, What is wrong and how can I correct this?

Hello,

All flat 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.....

Hope this help in solving the problem......

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...

I have a Sanyo 46 inch flat screen hdtv purchased from walmart aug. 31rst, 2008. Sure enough, 13 months later my tv is having picture problems and getting worse. It started having portions of the screen...


I have the same problem, my television is faded black on the left side with lines on the left top side. I have had the 46 inch unit for 1 year and 7 months. I am planning to write a demand letter to Sanyo and then taking them to small claims court woth evidence that this is a common problem with their units that they know about and is not trying to remedy. Also the Attorney general in Texas should have an interest in them (Walmart and Sanyo) selling these defective proucts in the state.

Had this problem also when I rebooted my Time Warner Cable box. Unplug everything from the wall including power strip and wait 60 seconds then plug back in and turn everything back on. Worked for me and havent had a problem since. Time Warner does not know what causes this yet.

Light green and pink spots on my hd tv!!!


Tiny particles of dust on the light engine lens can cause this (and was a service call for me about a month ago), or possibly the expensive light engine.

Rolling Screen


Does it do this on any other of its various inputs?
It is indicating that the signal is weak and we need to varify if it is just this one (whatever you currently have it hooked to).

I had the same problem w/ the same TV about 6 months ago. You need a new optical engine. Hopefully you are still under warranty. Once that was replaced, the tv looks great.
