It seems to me that you are watchin an analog signal on a digital HD TV, the analog signal is has a standard resolution of 720x576 for NTSC (American Signal) and 720x480 for PAL (European Signal).

It could be worth to go contact your cable company, they can hook you up with a digital receiver which gives a better signal and might even have a HD Signal (this means it has a HD-Ready 1280x720 of Full HD 1920x1080 resolution).

If you really want to use your LCD TV on his max this is really worth considering

If the video is shaking, zig zag looking, etc your hypermodule has failed. This is common on your model. Some peeople call it hyper board, hyper module, etc..all the same.

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,

HD channel picture is clear, but regular digital picture scramble


o.k. check all your connections
if you have a newer house check to see if you have a main hub in a closet somewhere and check all connections. Check your hd receiver and you may be able to chage the DPI the receiver receives in.

I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.

Things to ask also ? are you using cable or satellite.

If satellite T.V. there are other reasons you could be experiencing problems.

hope this helps!

Dlp tv has smattering of white (and just a few black) squares in upper right hand corner. Thick at corner then thining as spreads. Covers1/4 of picture. The rest of the picture is perfect.


You have a bad DMD board. It is easily replaced but not easily aligned. I would suggest having a technician look at the TV. The DMD board is the board with the million little mirros on it. The white squares indicate a few mirrors sticking in the on position reflecting the light from the lamp constantly. The black are just the opposite reflecting no light at all.

The tv seems really dark.57in theatrewide hd toshiba


Go into the tv menu and select the Preferences menu and set your picutre preference from Theater to Normal. The TV is currently in Theater mode, wich is for viewing with no lights on in the room. Switching it to normal lightens the pictue a lot.

The light engine bulb might be bad or going bad. Check it first. Then check its power source. These are you two most likely problems. I would suggest you having a TV technician perform this task.

I hope this helps,

I have an LCD TV. All of a sudden the picture colour has gone wierd. The best way to describe it is that it is similar to either a colour negative or one of those scientific 'false colour' images. This...


TFTs can produce a wide array of colors, but it takes an enormous number of transistors to make up a display, and a problem with any one of them creates a defective pixel on the screen. Typically this shows up as a bright spot on a dark background, caused by a damaged TFT failing to turn off a pixel. Most active matrix displays contain a few bad pixels, but a few bad pixels are not going to have much of an impact on the overall picture.
The properties of liquid crystal material can create problems with viewing angle effects, causing the image to darken, disappear, or reverse the dark and light tones when the viewer is not directly in front of the display (kind of like looking at the negative of a photo). The light bulbs make LCDs heavier than the plasma TVs (though they are still lightweights compared to CRT televisions.
Benefits of LCD TVs include a picture that can't burn in and doesn't deteriorate over time. Because of their flat-panel nature, placement options are plentiful, optimizing the cool factor over standard TVs

TV picture scrambled and getting worse


This can be a fault in the tuner, IF, or primary part of the video processing. With age and use some of the parts, and especialy capacitors, in these sets can become thermo sensitive and unstable.

To service these types of faults can be very time consuming. On top of this would be the cost of the parts.

Considering the age and type of set that you have, I would suggest that it is time to be looking for a new set.
