Black/Green Distortion - Picture Quality - Wharfedale

I have a Wharfedale LCD 26 HDMI TV. After owning the TV for 18 months the picture quality on all channels has suddenly started to show all black/shaded areas as green distorted images, a kind of green fuzz. All other colours on the picture are fine. Peoples faces and bright colours are all perfect, just dark/black areas now replaced by this green distortion.

I have checked all connections/scarts, tried adjusting all picture quality settings such as brightness, contrast, sharpness etc. TV is running through Sky Digital box but other tv's in house are fine using same Sky connection.

Any ideas???

    I have the exact same problem on an Emprex 32" LCD TV. This problem has appeared in a few forums around the web but I have not yet found a single explanation.

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

I need info on a particular TV


Resolution is 1080P (1920x1080). It is 3D ready, and has very good reviews from owners regarding picture quality and overall value. One limitation you will encounter, is that it is more difficult to see the screen from the side, than it is with LCD or plasma. Also, due to lamp warmup times, it takes longer for the TV to turn on. However, you will save a lot of money by purchasing a DLP versus LCD/LED/plasma.

Hello rqromero2,

I found this on HP's website. I hope it helps

Picture quality problems (such as lines, fuzzy image, or wrong colors)Check the cables and connections:
  1. Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
  2. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
    Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal.
    For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
    If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
    If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Open OSD to adjust the picture:
    Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed. 
    If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.

If this dosent solve your problem, letus know and we will find another solution,

Poor viewing quality


By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

Hi,

Below are some troubleshooting tips for a TV that has a fuzzy or blurry picture;

If your Plasma or LCD TV picture is blurry or fuzzy there are several things that may be causing the problem. It's worth running through the following list before seeking service. You may find yourself saving the full cost of a TV repair.

Make sure you are using the appropriate cable box for your TV. If you have a high-definition TV you should also be using a high-def channel box from your cable provider. Watching standard definition channels on a high-def TV can make the picture look distorted and fuzzy.

Not all cable channels are broadcast in high-definition. When you stretch a standard definition picture to fill the full frame of your wide-screen TV it may look distorted. You can try changing your TV display settings to show standard-def channels at their native resolution. This will create black or gray bands on either side of your picture.

Ideally all of your video components will be connected to your TV with HDMI cables. Your next best option will be component video cables. If your cable box does not have HDMI capabilities, contact your cable company about upgrading your box to one that does include HDMI.

Make sure there is no glare on your TV from a window or other strong light source. This can significantly degrade the quality of the image you are watching.

If your TV has digital noise reduction, try turning that feature on.

You can adjust your TV's sharpness and picture modes to see if that improves picture quality.

Try plugging the power cord into a different electrical outlet and/or surge protector. You may be receiving electrical interference through your power cord.

Trying moving any nearby electrical devices away from the TV. They may be creating interference that can degrade the picture quality.

Let me know if the above helps or not, so that I can direct you further on what do next.....

Best regards.

Hi,

Is it a Duplicate Question....Wonder why?

Same reply :0


This is an internal Fault. Diagnosis is required to make sure whether it is Failed T Con Board or Light Engine. I do not think that it would really help by changing the TV settings. This was a Common Problem with Old LCD's where you got Blurry Spots specially while Playing Real Fast Movies or Games. On Few Occasions, it as Corrupted Firmware.

As i cannot see the Video or Screen from here, more likely what i could guess it is an Internal Fault as you have tried using HDMI, Use different Setting Combination's and you got the same Picture Quality with DVD as well.

So, what i could suggest, get back to the Seller and Lodge an Official Complain and get it Replaced. There is no point in Opening and TV and Inspecting it and Replacing Components when it was less than a month ago.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Just purchased tv and the quality of the picture is still fuzzy tried to mess around with the resolution but it still isnt very sharp at all


Hi,
The TVs produce picture using entirely different methods. Usually the colors and especially level of black color are better on plasma, LCD will have some trouble various shades of gray and black especially shading on peoples faces etc.. This is not a defect in the LCD just a limitation in current technology.

If you haven't already bought a nice set of HDMI cables, go ahead and do so (just dont fall for the "gold plated" cables as they are a gimmick). Unfortunately, while we all want that HD quality, there seems to be some problems with the ln46a530 when switching from RCA to HDMI. On the bright side, they have been resolved in this forum post.

Poor picture quality on my samsung HD TV


Hey xf1racer,

Based on the description that you provided, it sounds like you are using a bundled composite video cable to connect your cable box and TV. Composite video cables generally consist of three color-coded cables: one yellow, one red and one white. While the yellow cable is typically used to transmit the video signal to your TV, the red and white cables transmit the right and left audio channels respectively.

Red/green/blue bundled cables however, are often referred to as component video cables - each of the three colored cables is used to transmit a different portion of the same video image from one device to another, and require a second separate cable (typically red/white) to transmit an audio signal.

The primary benefit of using component over composite cabling is that many users may report a cleaner, more brilliant image on their TV as a result. Please keep in mind however that this is not a guarantee that changing from your current set-up to component cables will improve the picture quality on your TV, as picture quality is often based as much on personal preference as it is the actual configuration and settings of the equipment used.

Additionally, many retailers may suggest changing your current configuration to one using HDMI cables instead to improve picture quality even further. Unlike composite and component cables, standard coaxial cables, and S-Video cables which transmit analog signals, HDMI cables are designed to instead transmit uncompressed digital signals. This typically means that more information is available for your TV to process in terms of color hue, color intensity, as well as image resolution. Again, remember that any perceived improvements will be based on both personal preference as well as your home theater configuration.

Should you have any questions or lingering doubts, I would strongly suggest speaking with a Magnolia Home Theater agent at your local Best Buy™ store for more information. Most stores will have similar TV's on display using more than one type of connection, and sales associates are always able to provide additional suggestions if desired.

Hope this helps you out.

Sincerely,
Aaron

Sounds like you either have a bad card or a bad HDMI cable. Scarts are not the most dependable when it come to HD imaging there is alot of converting going on espically if the TV isnt NTSC standard to begin.
