In some cases the buzz is external. The vibration of the unit may just cause a tray, flat surface, or other surrounding attachments to rattle and buzz. Look for anything that may be loose or laying on or about the TV.
Get the estimate. When your insurance company sees it, believe me, they won't buck at replacing your TV _especially since the prices of TV's have come down over the years while the quality and resolution has skyrocketed. . .
Hello; If you have a plasma TV, is fairly common to hear buzz noises. They can be always there or intermittent. They can get louder as the screen gets brightest. If the buzz is noticeable when you are at normal volume setting, the buzz is excessive and a PCB probably needs replacing. These buzz noises are almost never a sign of failure or safety. LCD TV's can also buzz, but the same applies. John
I have this tv aswell, and yes I will confirm that it does buzz quite alot, but all plasma tvs do, it is to do with how it renders images, the buzzing can be made worse by it being close to a wall and it reflecting back. I found that my tv stand some how amplified the buzzing when i got mine. I dont think its something you can escape.
Mine i notice also when scrolling around menus seems to have lines that follow your selection....not to pleased about that
the buzzing noise you are hearing is from the lamp ballast as it strikes the lamp. that is quite normal but it should only be momentary. it should not be constant.
When we turn our TV the humming and buzzing begins! We cn mute it and it goes away and then it when we turn the sound back on the sound is back! How can we fix this?
Is the lamp light the only one thats flashing? Does the buzzing your hearing stop or is it constant? Also when you press power off does the buzzing stop instantly or continue? Respond to this post and I will try to assist you. Is HL-R677w the correct model number also?
You haven't specified where the buzzing sound is coming from, if it is coming from speakers, changing capacitors in the audio section will fix the problem, especially the filters. Now if it sounds like a hissing sound from back of the tv, the CRT base socket is the culprit. It is an easy thing to fix, and the base is cheap, but make sure you purchase the exact same type of base or it will harm the CRT. Good luck.
