Static noise and blurry screen


You need to take your TV set to Service Center, because the inner parts, especially the flyback transformer, been damaged or worse, the connector broken, that's why you can hear the noise.

Wifes ge tv won't stop changing channels just keeps rotating like it's on scan and won't stop even when we go to menu it keeps rotating through options


I suspect one of the buttons on the front of the TV is stuck. Best thing to do is try playing around with them while the set is in operation and see what happens. If that doesn't seem to be the case then you have a diode or capacitor on one of the control lines that is shorted or leaky causing this to happen. This would require a technician to troubleshoot that issue. Please take a few moments to rate my answer. Thank you...

Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Sony Trinitron: Frozen Static Issue


you could be experiencing two problems. the first part of your description states the static with two horizontal bars, this problem is usually erratic and it is caused by a defective varactor tuner(this happens while watching a channel thru your channel selector) the second part that it also happens while using the front hookups could be taht the front input connectors have developed some loose solder connections and thus the video problems (very common problem)

TV Making a Loud Noise


this can happen with the flyback transformer's brightness which can be adjusted , also the power transformer can make humming or buzzing sounds which can't be adjusted , also this can happen with the picture tube or the CRT board failing , and sometimes chips with heat sinks or the IC's themselfs

Hi,

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.

Older TV keeps going to static


Without seeing it I would suspect a bad connection on the main board. As the board heats up the board expands and as it cools in contracts opening and closing a crack in the board. Sometimes a crack or bad solder joint both are sometimes hard to find and it is a lot of solder and wait and see.I have had some luck by tapping on the board with an insulated handel of a nut driver,.. the tv on and watching for any change. If i tapped around the board some areas were more sensitive than others. I then soldered that area. I would tap around again if the set did not react I assume the problem fixed

Sansui TVM1915 Sound just quit!


if theres a headphone jack plug in a set og headsets. if the sound is there then you know that your speaker is bad. if its not make sure the volume indicator goes up and listen closely to the speaker. Do you here static noises?? NO? ok then its a problem with the audio output IC built in to the set and this is probably something you cant repalce unless your experenced with soldering printed curcuit boards. If you here staic or a small his then the volume contrpl curcuit or the audio if is defective and this as well is not something you can diagnoise unless you know how to troubleshoot electronics. Good Luck
