Question about Protron PLTV-32 Television

Loud sound from tv

We just had our Protron 32" LCD make this loud buzzing/crackling sound, the thing is the volume is all the way down? Is there some internal component that is faulty? Do I need to buy a new one rather than fix it? Please help!

It could be the inverter board going bad. The inverter board is what makes the back lights come on and has transformers on it that have high voltage. any time you have a noise like a buzzing or arcing you should have it checked

It sounds like you've done quite a bit of troubleshooting, which I applaud you for doing. Have you tried power cycling the TV? Simply turn off the TV, unplug it (and any components connected to it), then plug it back in and turn it on after a minute. See if this corrects the issue. If it doesn't, then I would recommend calling our Product Support team to schedule repairs at:

Vox ac30cc2x fault finding


Check valve you replaced has made proper contact in socket. Plug it in and out a few times to clean pins. Is inteference/crackling noise there when volume is turned down to minimum. This should tell you whether the problem lies before or after the volume control. A good clean can solve many faults. Servisol on pots works wonders.

I have a Protron PLTV 32' LCD and its making crackling noise out of the right speaker.


Hello
If the crakling sound is from only comes from right speaker, it will be a speaker trouble. In some speakers, the voice coil will get damaged, and if so, this kind of distortion will occur. Replace the speaker with same type and diamensions. Note the 'Ohm' [resistance] of the coil, which will be marked on the speaker. There will be markings like 4Oms 6W, 8Ohms 10W or so. Choose the correct value of these. That is the only thing should mind when choosing speaker. OK.

Luckinfutz, My Protron 32in LCD tv speakers crackle and even when the volume is all the way down we get this loud hum for about 5 seconds. I think the speakers are shot and are on their way out. I read...


Yes, changing the audio board might solve your problems. But the loud hum is the generated by either a bad connection (open the case and check all of them) or a bad filtering of the power (check the capacitors on the power board) so try fixing it first.

Loud buzzing noise on vizio tv


It sound like you may have sound processor problem which is part of the main board, I would also look at the 12vdc from power supply to make sure it is clean DC.

Loud buzzing sound which is getting louder than the speaking


Most likely a capacitor going bad. If it gets louder after the TV had warmed up for a while, remove the back and blow all the dust off the circuit boards. While you're in there, look for a capacitor (google if you don't know what that is) right next to or touching another component, especially a resistor. Carefully bend it away a little to reduce heat transfer. If it's not a heat-related issue, it'd likely cost more than the TV is worth to have a repair shop fix it. Consider running the audio through a separate sound system. If it buzzes even with the TV volume turned all the way down, disconnect the internal speakers.
