Re: every channel is static, no sound

I had the same problem, static but no sound. I took the TV apart and vacuumed all dust from it. There was some pretty heavy dust in there. Once I put it back together and turned on, all worked great.

Re: every channel is static, no sound

Unplug the tv set for 30 seconds, plug back in and turn set on. if this does not return your audio you need and you're NOT still under warrantee you should at least open the TV and check the board where the components are mounted and resoled any that look bad. In your case it could caused by a blown fuse, a leaky diodes or a bad solder joint. All can be replaced at a local electronic or hardware store and they're easy to replace good luck

How do I watch a DVD with this tv. It seems like it is connected right but just showing static

Hi. By static, do you mean 'snow' image ? DVD players must be connected to AV inputs and selected as an AV signal, either by using the remote control, either using the local controls in the set itself. If you see, what you call static, means that your TV is on "a" channel without areal input. (antenna inputsignal).
You can use the local TV channel button (-), go all the way down below channel 1. There the AV inputs are located. Good luck.

When using cable input video is good but sound has fuzzy static

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.

Static on all cable channels

The tuner is questionable The problem lies inside the isolation box. Ask a repairman to open this isolation box and resolder the small board. There are two small resistors that need resoldered. This also has the rf connector on it. And you may have him resolder the tuner if this does not fix it. Have him inspect any and all grounds on the main board as well. Good Luck

Suddenly no sound & no picture overnight: is my TV dead?

If you have static siugnal, sure TV is not dead.

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.

Hi Suezie,

The problem is most likely your SAP being turned On.

SAP was created for audio programing including translations into a 2nd language. On nearly all sets, the SAP being ON will essentially select an alternate audio stream and will de-select or mute the main audio from the channel your are viewing. However not all TV stations have SAP enabled.

I am the Chief Engineer of a TV station in Denver, CO. We are not using SAP so if you selected SAP while watching my station you would get noise or static. There would not be any audio there.

Go to the front panel of your TV and select the "MENU" function. Step through the menus to Audio features and De-select SAP or Enable your main audio and this should take care of the problem. Alternatively you might be able to unplug your set for a period of time and it would reset itself. I used to get calls from elderly viewers when the set wouldn't pick up the UHF TV stations anymore. These were always after a power failure and the set had defualted to factory settings,

Different set manufacturers use different menu schemes and withou a password feature, these menus are so simple a small child playing with those fascinating buttons can change them for you to something you really don't want.

Good luck and write back if you can't find it. The set manufacturer and model number would help me look up a menu tree for your TV set.

Thak you,
Bernarr Howell

White Noise Sound

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. Stargazer
