Question about Sanyo HT32744 32" TV

Audio has a lot of static

I am a cable user and recently this tv has lots of static noise. All other tv's work fine. Static level not affected by volume control. I unhook cable and still have the same static level with sound on mute. The only way to stop static noise other than turning tv off is to let tv autoprogram channels but once that process is over it starts up.

Re: Audio has a lot of static

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.

TV was fine, now just static but works with DVD

Try using AV cable the same way you do when you hook up the DVD (- hook the cable box in place of the DVD) This will determine if you have problem with the tuner of the tv.

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.

Appreciate the direct "Ask Me".

Technically, when a TV signal is said to be snowy, it indicates that the incoming RF signal is weak; on the other hand, when a TV signal has static, this refers to electrical noise that goes with the TV signal.

Having said that, then to your concern:
  • for snowy signal, it is the cable providers problem. They have to change where your incoming cable is tapped from, check/replace the feedin cable itself or worst case scenario, replace the line amp/distribution amplifier feeding your cable input;
  • for static noise, what is required is to check possible sources which could include (but not be limited to) electronic ballasts of florescent lamps, electric fans, hair dryers, shavers, wireless phones, computers and others.
Additionally, you may want to check if you have any RF producing devices attached to the TV such as VCRs, DVDs, game consoles. You can try unplugging them when not in use.

Worst case scenario is the tuner block of the TV is getting weak (unlikely but possibly). You can try rewiring the cable to feed first into a VCR, connect the VCR to any of the free Video IN, and select channels through the VCR. If significant improvement, then you have just confirmed an internal fault with the TV tuner, if problem persists, then the static/noise/low RF is caused by something else.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Blurred picture with lot of static

This model has a chronic problem with the crt socket arcing and causing this problem. The only true fix is to replace the crt socket locate on the small bd. that plugs on the back of your picture tube. You can however have some success by locating the focus control on the flyback transformer and slighly adjusting it until the unit stops arcing. If you are not familiar with high voltage safety then please have a qualified service tech perform this repair.

Cable connection generating static on screen & noise

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...

No sound

you need to check the sound ic in that audio section. check how much voltage you are getting on the legs of that ic. you need at least three voltages. about 32 volts. if you are getting that then replace the ic righ away. if you are not getting it, then you need to check around that ic to find out what is keeping the voltage from reaching that ic. good luck

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
