My Toshiba 40" LCD TV Has High Pitch Buzzing Noise

Been like this since I bought it, I turn it on and theres like a whistling noise (imagine having tinnitus - that sorta noise), Can hear it on low volume but I turn the volume up to try and drown out the noise. I'm ringing toshiba next week, just wondering if theres any fixes before I ring them and get a service charge! Thanks

I think that the pop you heard was an electrolytic capacitor blowing its top on the picture frame board. If you are able to check this for yourself by looking on the board for the one/s with a bulging top or are a brownish/black colour like something has caught fire. And also in this situation smell can be of great help as it will smell burnt out but PLEASE before putting your nose or anything else in the tv take all necessary precautions against electric shock and discharge any electrolytic capacitors in the vicinity. If you are not able to do this yourself find a competant technician. Hope this helps.

It sounds like you have a quiet cooling fan problem. Those particular types of tvs are notorious for that kind of a problem after a couple of years. You can take the back cover off and remove the fan. Pretty straightforward and go to an electronics supply house and ge a matching one. That is your best bet of fixing the problem for yourself. God bless you.

Buzzing/fizzing noise from back of sony flat screen tv


Below is an image of rear side of your TV, Sony KDL-40W5500
Top right corner is marked there and possible cause of noise seems back light inverter board, there are high voltage going to CCFL inside LCD panel and seems high voltage leakage causing that buzzing/ fuzzing noise.

Replace back light inverter board upon voltage leakage confirmation.
Thanks.

There may be a small hole or cut in a vacum line or possibly just loose. Also make sure the air filter box and the big hose to it are secure and clamps etc are tight. Pulleys and belts can make a high pitch sound also.
