there is sinal interferences from laser products pc mobile transmitters or video games get high quality vcr and cable tv cables move or switch off any video games cd players energy saving lamps or pc and microwaves n motors like pumps change the position of installation of cable and antenna to avoid path of interference
Your TVs tuner tuned a little off frequency. It could be as simple as having cable box on where you have good picture but fuzzy sound, use the TVs remote to change the channel and then change it back to proper channel. If that doesn't fix you may have wrong tuning type selected in channel set up menu.
Check the aerial cable, ensure it is well plugged in and getting signal.
If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.
Test the TV on standalone , connecting it to an external antenna. Tune again the channels, and save the preset. If still no signal then the antenna socket on the TV may be defective.
Try using the TV with a DVD.
If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.
Call the phone number listed on tv user manual to get support, and eventually repair it.
well tuners are being made smaller (and there is more cold solder in some points due to heat) so i would look up a new tuner for that tv...and if you know how to solder ,do it yourself it will be cheaper
Hi, it sounds like ya most probably gonna haveta resolder the Cable Connection Socket internally.. they often fracture, OR perhaps it is the Actual Cable Connection Plug itself?.. maybe you need to remake this input connection? Indeed it sounds as if the Earth Shielding is making bad contact...
Your problem is somewhere between the tuner and video detector circuit.
The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess!
After the audio passes through all this, it is detected and sent to the audio processor.
If any frequency has drifted away from it's value then you loose the sound.
SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem.
You can possibly diagnose the problem by trying a different speaker,it does not have to be the same shape as the original but it has to have the same amount of resistance (ohms),radio shack might have one that you can try or one from a broken radio ,if you use one with different value it might not sound as loud but we are trying to see if you hear the static or is gone.You need to unplug the unit from the wall,remove the back cover and locate the speaker,disconect the wires and reconect the one to try then plug the set and turn it on,the antenna will need to be reconected too.Is the most simple test you can do without getting in too deep.Let Us know how it goes by a way of a new question or if you need more information.
