Whenever i connects the tv to cable, the tv is telling me no signal.


well you either don't have rf signal to your cable box and you need to call your cable company or you need to switch the input or source on your t.v.

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,

When the cable company offers you digital cable, you typically need a cable box to unscramble the digital channels. Therefore you need to connect either a coaxial cable from the cable box's RF output, if it has one, or connect 3 RCA cables from the yellow, white and red jacks on the rear panel of the cable box to the TV. Analog channels only (if available) will go straight thru over the coaxial RF hookup. They are not scrambled. Select the proper input source on the TV for the cable box.

VISABLE LINES IN PICTURE


Bulb replacement will only repair reduced brightness or contrast problem. Sometimes shadows or lines (usually curved or circular) appear in the image if the bulb is weak or faulty. This will show with the color turned off and a black and white image displayed.

Most visible color faults are caused by optical engine failure. Big cost, as the complete assembly has to be replaced.

Occasionally there are video processing or tuner problems that require serious troubleshooting to determine what board has to be replaced.

If the fault is not visible on the customer menu and appears only with input signal viewed, you may have a cable box or other signal input problem. Check various input signals to see if the problem is visible with all inputs.

Running the channel scan with vhf input signals sometimes clears up a lot of problems. Your cable company may have changed or adjusted rf modulators or other equipment and the tv needs to be aligned to the changed signal. Auto tuner scans will take care of these problems.

Our first tv has a booster amplifier on the coaxial cable, i have purchase a new tv and need to know what product i need to us to attached the new tv's coaxial cable too. We have used a splitter box, but...


To have good picture quality you need zero DB (decibels) for one TV without a splitter. You can use and inline amplifier for each individual TV hooked up to the cable input with a output leg connected to each TV. If your house in wired in parallel (one main input hooked up to a splitter with all of the other TV's run off of the splitter) you can use a whole house amplifier hooked up inline between the input line and the splitter. If you house is wired in series (the input goes to the first outlet, then splitter to second outlet and so forth) each splitter knocks your signal levels down 50% each splitter. Amplifier placement depends on how the home is wired and how many TV's are in the home. Splitters can be either balanced (50/50 split) or imbalanced (75/25) etc. On a two way splitter 75% of the signal goes out one leg, while 25% goes out the other (usually for FM transmissions). If you have a three way splitter the signal is divided by the number of output legs. Splitters do go bad as well (sometimes only one leg). You can also buy an amp that is multi- port (which splits the signal and amplifies in one unit/ one input and 2,3,4 outputs). Amplifiers are electric and there is no way that the splitter can interrupt the power that would take all the signal away. If you meant that it drops the signal level so the picture is unacceptable, that's different. If you have another splitter in the house try using that one, the other might be bad. All in all you can purchase most anything you need at a Radio Shack and are very inexpensive. Amps can be purchased in different gains (boost). +10db, etc. I cannot believe that your cable company is giving you such minimal signal that 1. you need an amp?, and 2. that one splitter drops your picture to nothing? Your line extenders (amps for the lines that feed your neighborhood) might have problems or need adjustment by the lazy, cheap, cable co. also. I had problems with my cable company (when I had one) my modem would not stay online. 4 months later, they diagnosed the problem and my drop (RG56 cable line that feeds my home from their tap in the cable box outside) was bad. My friend could stay online and 2 months later comcast adjusted their amps (line extenders) in the neighborhood and then he was fine. I know this is a lot to digest, but I'm just trying to draw a clear picture so you can understand it all. I hope this helps and good luck!

Pixelation


This model has been known for problems with the Hyper module but the picture would be affected with any input source.HD or not.The cable converter box and the cable signal are the only culprits for pixilation.Pixalation is the result of missing digital information via signal.If it is only appears on the HD signal I would suspect the cable signal or the converter box.I assume you are using your component input on your TV or the HDMI input.As a technician I would suspect the cable box or cable for pixalation.

Problem w60 inch using hdtv cable box


i know this problem, happened to me with the comcast Motorola HD receiver box. The key is with the setting in the cable box. Switch on the TV. Set the channel to normal tuner channel 3 or HD input. Turn off the cable HD box. Press the Menu Button on the Cable box or the remote. You should see a Menu. Use the cursor keys to navigate The default setup is also one of the option, Right click on your cursor keys acts like the computer keyboard enter key and applies the change. The default setup is 16:9, the shacking would happen if you have set the picture type to "PAN SCAN". change it to either 16:9 or 4:3 Letter Box. The shacking should stop. Hope it helps.

Video and Sound Going Out


Your problem could be the cable: A. A weak signal coming from the cable company B. A bad cable or connector within the house. For the above, call the cable company and ask them to check the signal levels on your block. And, remove the plate where the cable comes out of the wall and look for shorted or bad wiring that may cause a weak signal. Also, if you have another set in the house, connect it to the same cable outlet to see if it has similar audio blackouts. Your problem could be the tv set itself, as well. C. Go into the on-screen-display and make sure you are on stereo audio and NOT SAP. SAP settings are not to be used unless you are using the second language or audio program feature. D. The sound detector inside the set could be defective. Which would require service. So, the first thing to do is to determine exactly where the fault lies; inside the set or outside the set. Then attack the problem at hand. If the set is defective internally, I think you will need a tv tech who can diagnose the problem; it must be tested and measured to find out the exact part (this set has over 3,000 compnent parts inside).
