When ever the picture freezes intermittendly the problem is usually poor connection on the signal line (antenna or connection on tv) or poor reception. Could be the tuner if the tv has one.To eliminate the tuner possibility try anther tv set if possible.
If you still cannot figure out the problem,let me know what kind of set up you have connected to your tv set.
Do you have a satellite or cable box and if you have splitters.

Picture breaks down on some stations saying no signal or signal weak.


2 possible solutions, 1. If you have any type of dish network, go into the service part of the menu and check the signal strength usually a signal on any of the transponders less than 70 will cause this on some channels due to thier own signal. You can have either a tech come out,( sometimes for free, or you can adjust the dish very i reat very small increments so as not to diviate from the correct izmuth setting originally aimed at. to do this, you can do it yourself by selecting signal strentgh meters on the menu and raising the volume so you can hear the repeated blips while adjusting the dish. The sound your looking for is like the old Pong game on atari. The faster the blips, the stronger the signal. Slower blips mean your aligning the dish in the wrong direction.

2. Check your coax cables. If their old, they may not support the bandwidth being sent through it. Check at connections, ( All of Them) they wear with age. Is the cable itself at the connection protruding enough to enter the receiving female part. When you unscrew a coax at the connection, it should have about 1/8" to 1/4" copper cable past the connector and in clean, good, straight condition. make sure they are tight, and good luck

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,

You need to try and isolate the piece of equipment which is causing the problem.

You've already tried the aerial lead direct to the TV and this is OK.

Disconnect all scart leads and try the RF on its own.

Try the Aerial lead to video, then video to TV.

Try aerial direct to Sky box, then to TV.

Try just connecting the RF out from the Sky box to the TV (no aerial input), can you tune into a good channel 68 picture from the Sky box.

Then Try the VCR to the Sky box (no aerial input), see if you can tune into the VCR and Sky channel.
Hope that helps.......

Can you tell me how to tune in a channel when ppreparing to use a freeview box on a onyx sw 1536 ld


Unless you've got an "expensive" Freeview box that modulates its output on to the RF (Aerial) connector then you can't. Most Freeview boxes have 2 aerial connectors - 1 IN from the Aerial itself and 1 OUT to connect to the TV - BUT this is ONLY a PASS-THROUGH connection. This means that the digital Freeview signal which is decoded from the aerial signals is NOT output on the OUT connector and sent down the co-axial cable to your TV. Only the "old" ANALOGUE (not Freeview NON DIGITAL) comes down that co-ax. What you should do is connect the Freeview box to your TV with a SCART cable via the SCART connectors on both. You need to select the AV input on the TV using the remote.
Even if you do have an "expensive" box that does modulate the digital decoded programmes and output these of the RF OUT connector, you should still use a SCART cable as the picture produced will be far better
Hope this helps

Picture and sound problem


If your getting your signal via a satelite receiver or HD cable box, its likely that the sound dropouts and picture freeze are the result of marginal signal strength. Does the TV ever do this when using a DVD player? If not, its certainly the quality of the signal.

If the TV is at fault, the problem will be on the digital board.

New aerial wont pick up digital reception and fuzzy picture on terrestrial channels


Hi.

If you put aerial up your self was it wide band aerial ?
Is it in the atic or on the roof ?
Have you used decent quality cable (not the cheap stuff)
How long is cable run from aerial ?
Have you checked that when you fitted rf plugs that none of the braid strands are touching solid copper inner core ?
Ask an earial installer or Tv shop what the signal strength is like in your area.

WS-65807 picture goes black when using HiDef Signal


Tank, If the unit operates correctly on DVD then we can assume that the signal chain and display is operational. Can you substitute the Directv receiver to rule the box out as part of the problem? I know they came out and checked but how exhausting was the testing? Have you checked signal strength on the directv on screen setup? Low or marginal signal strength could cause intermittent blanking. When the screen goes dark does the audio continue? please let us know..
