Question about JVC HD-61Z886 61" Rear Projection HDTV

1 Answer

My speakers just started making crackling noises.

I have never had this problem before. Everything else works great. Crackling coming from both sides. I made sure they were connected well and not vibrating because of loose speakers. HELP!

Wavey color lines at bottom of picture. Crackling noises coming from back bad picture


Howdy;
The "crackling noises" from the back is causing the picture to distort. 1) Either locate source of "noise" and correct or 2) Call a Service Company and get corrected. I would recommend that you DO NOT USE TV until this corrected. It may cause a fire inside your TV.

Good Luck, Big Irish.

CRACKING NOISE COMING OUT THE SPEAKERS


Your speakers need replacing or you could turn down the volume till it stops and use it like that if it's not too quiet.

Sony wega kdf-50we655 went off and thier is a buzzing noise


Anything that sounds like electrical crackling will be coming from either the lamp or lamp driver/ballast boards or their interconnections. The lamp should be examined first as this is the most likely cause.

I have a 42 inch phillips model 42pfl7662d 1080dp lcd tv. today it started making crackling noises at the rear right hand side, then it automatically switches itself off, and then on again after a minute...


sound s like the HV generator (flyback) This is repairable with a new flyback if that is indeed whats happening. Take the back off and dont touch anything but try powering up the set and see if the noise is coming from a part that looks like this with 4533b6a8.jpg big red wire coming from

Akai PT5598HD 55 in. Rear Projection


Something like this Id have someone who knows there way around electronics, a qualified tech or someone you trust really well :-) Does the crackling affect the TV picture at all ? My first guess would be dust and or dampness on the audio components. Sometimes this can conduct electricity across small pc chips and reak all sorts of havoc. I had an old Tomas electric organ once, and it actually caught fire because two speaker wires were rubbing together and eventually wore thru the insulation and shorted out, but it was also making alot of crackling and static noises. Try raising and lowering the volume low to high and high to low and see if the crackling noises gets worse. Some audio amplifiers put out quite a bit of power, so I wouldnt trust leaving the TV on without a fire extinguisher handy.
