1 Answer

TV Doesnt work

Power the tv on and you can hear an odd humming/buzzing sound coming from the circuit board area. There is no picture and no sound on the tv. The little red indicator light does flash a few times on the front of the tv but that's it.

Was working fine last night ,went to turn it on and you can hear a buzzing by where you plug in your jacks a bee,or high pitch sound.tv has no picture or sound.only sound you hear is this buzzing



Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.

Will not power on just making a high pitched humming sound


It seems that the SMPS is loaded as the driver is cut off on protection which makes the whining noise. You will need to remove the panel after disconnection of power, disconnect power to the main board and see if the +B voltage comes up on the circuit.
If so there is a short in the mainboard, can be the drivers shorting. Check with the multimeter to confirm

My sound is not working. I have a picture but no sound


Hello
Pictrue being Ok and there is no sound is your problem. It may be either fault to its speaker or it sound output Ic. You can be sure about which of this has got troubled by yourself. Keep your ear very close to the speaker side of your TV, and switch it "ON" bu "MAINS", not by remote control. If you can hear a "Thumb" sound or a "Hum" sound, you can make sure that your TVs speaker is OK. If there is no sound at al, it means that there is some fault to your TVs speaker. It can be due to a socket trouble also. If there is an earphone socket in front panel of your TV, just insert an earphone pin into it and check whether sound coming from it or not. If there is sound through earphone, and when it is unpluged, sound does not transfer to the speaker, means that socket has some trouble. Replacing it will solve the problem.
If you hear a "HUM" sound, as decribed earlier here, this may due to the Sound Output Ic inside the circuit borard of your TV. To rectify this fault, ypu have to open your tv, and locate the sound output ic. Just follow the speaker wire, and somewhere near it orginates from the mainboard, or other board, can locate it. Usually this IC will be screwed into a metal plate, inorder to radiate heat from it while working. Check for any loose solderings to its legs, that may also cause it to be nonfunctional. Anyway resolder its legs first by applying a little more solder, and check the result. If this also doesn't help, resolder it out from the board, and go for a same type and number. Replaceing it will solve the problem. Ok.
Take every precautions before you open your TV. Keep children away from you while you are working. Never allow to them even stand beside you, and allow an adult beside you as a pracationary measure, and as a helping hand. Keep AC power chord out of wall socket each time you make contact with the inner circuit board of your TV.
If you wants any further assistance, inform me through Fixya.

My tv is ringing, how can I fix?


is it like a buzzing sound? is so then it would be coming from your speakers. and would possibly mean a new sound board is in order. another possibility is that their is a hum from the power supply unit. but that's the power control board on the tv. this can also cause audible humming. if it sounds like a high voltage hum from a 60 hertz cycle then it is the power modal on the board failing more then likely.

good luck with it. and get a second opinion as i can easily be wrong. thanks for using fixya

Buzzing in television


Sounds like power supply buzz. Usually means dried- out electrolytics, U need a serviceman. Could be frame buzz, but I think unlikely.

Buzzing sound, no picture on my Panasonic TV


You might have a short causing the set not to start. Probably in the horizontal/high voltage circuit. The buzzing sound that you're hearing is the power supply overloaded. Stargazer
