Very poor picture quality on LG 42" SMART TV 18 months old


This is probably due to poor quality cable or connections from the aerial. Digital TV needs better quality in both (F connectors and quad shield cable) than analogue TV did.

If all that is good then you may need a better aerial or even a signal amp.

TV comes on but will not recieve channel. It displays no signal & the code65535. The cable is working here so it is in the TV. It is a 37" dynex flat screen bought 2 yrs plus 4 months.


Hello
Try the resetting the TV. To do this unplug the power chord from power socket, and wait for atleast 45 minute. TV will reset itself. The try to get signals.
If your TV receive poor quality telivision signals, captioning may contain errors, or there might be no captioning at all. Some possible reasons for poor quality are automobile ignition noise, electic motor noise, weak signal reception or multiplex signal reception like ghosts etc.
If reset also didn't help you, the tuner inside your TV is defective, or weak. It should be replaced with same type and number. OK.

TV is brand new out of the box. Watching television last night and noticed horizontal green line "blips" flash periodically throughout the night. Why is a brand new television doing this? These...


It could be localised interference, try different modes. Maybe it is a poor quality connection on a cable?
If all else fails www.toshiba.com will get you to the technical team for assistance.
You could always take it back for an exchange of course.

Poor picture quality & audio reception


If the input to a HD tv is not in HD format the tv won't display an image very well. Be sure your input to the tv is compatible with the tv's technology for optimum performance quality Also re-check the input source (such as converter box, dvd player, etc..) and be sure you have the correct input/output ports connected properly. Try to reset all yout tv settings back to manufacturers defult specs. When an input signal is sent to the tv most modern tv's have software built in to select the proper format to display the input image. There may have been a mismatch communication error when your tv software tried to "handshake" with your converter box input signals from its firmware. So try a reset solution and re-connect the tv without the converter and see if that helps. If not e-mail me and I'll determine if the tv needs technical servicing.

Red pixels on white images on screen


This sounds like the digital equivalent of 'snow,' a random noise that can come from poor signal quality or poor or not firmly attached cables. I'd try exchanging the cable that is now in place from whatever signal source you have (cable/cable box, satellite receiver, etc.) with another either new or temporarily borrowed one from another device. 
If this doesn't help, consider the other modern devices you have in your home such as light dimmers, fluorescent bulbs, digital clocks, home theatre equipment, etc. Pull the plug on any of those, one at a time and observe the TV to see if any of them are affecting it. Those named items are common sources of high frequency noise that can contribute to the kind of problem you are having. They have gotten better but can still produce unwanted sources of interference signals.

  1. Check the cables and connections: Make sure that cable connections are securely fastened to the connectors and try reseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degradation (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.
  2. 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.


  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.

Hello,

 

Picture quality problems (such as lines, fuzzy image, or wrong colors)

  1. Check the cables and connections: 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. 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.
  2. Check the  display issue with  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. Try to Reset the TV ( LCD) quality options. Please look in to User Guide to make the TV to factory Defaults..
  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.

I hope that this should resolve the issue. However, if the issue still persists then please contact LCD manufacturer for further more on the issue.

 

Bye.
