Question about Televison & Video

1 Answer

I have an 18 month old acer AT3220B TV - it has always had a rather loud humming noise in the background and also the volume adjusts itself?! Now I have a vertical black line down the RHS of the screen? A friend also bought the same TV at the same time as I did and within 3 months had the black line in the same place as mine is - he was told the TV was not worth fixing and was given a replacement TV. Mine is still under warranty. I am curious what causes this black line? the humming noise? and the crazy volume?

The TV reciever is capable of recieving an interference especially if your mobile cellphone is near the TV otherwise the black line which is shown on your screen is not normal,you have to sent your unit the service center.....

Flickering screen, loud buzzing sound, self boot down.


Color wheel bad. Makes rumbling sound. Bad bearings. Has to spin about 10,000 RPMs and sync to DLP chip. Here: https://www.encompassparts.com/webwiz/wwiz.asp?wwizmstr=WEB.SEE&partnumber=5933777&smodel=HLR5067WX/XAA

The background noise in a movie on Tv is so loud I can hardly hear the conversations. I have tried the audio menu. Normal, Wide, Low ..They all sound the same.


GO again into the customer menu and look for something that says Hall, Surround etc--I have seen this before--usually it is a setting that creates a problem where the background sounds are so loud you cannot hear the people talking......go thru every section of the menu--I be you will find this is your problem.

Let me know what you find--I am here to help people. I do not think you have a circuit problem--only some thing in the menu has been set to the wrong place.

Buzzing/humming noise that increases as you raise volume. So loud that you can not even watch tv


Hello snow1525,

You may have a torn speaker element. This is usually the cause of buzzing noise in the sound, also you may have a bad capacitor in your audio section. This is what I would suggest doing as a test open the front bottom panel of your TV and visually inspect the speakers for signs of ripping and or tearing in the speaker element. If the element or elements are torn it may be possible to repair it with rubber cement or rubber paste just coat the tear with the rubber cement to hole the torn edges together and allow it to dry for two days before testing the sound. If the speaker elements are not ripped then the problem may be a bad capacitor either in the audio section (power supply) or in the filter block (usually attached to the speakers to separate bass and treble signal to the speakers.

I hope this helps,

Thank you,

TV making loud humming noise


Sounds like u need a color wheel

No picture or sound


Hi, your color wheel needs to be replaced, the bearings fail causing the grinding noise, the new ones use "air bearings" so they are supposed to last much longer, video-tek

Toshiba DLP fan noise (52hmx95)


i constantly hear complaints about fan noise in dlptvs if you sit in front of your computer you will hear the same noise even in the next room there is no solution to the fan noise problem this product has a huge cage fan and a second and third three inch fans in it.... more than the samsung product it can be noticeable if the tv is on hard surfaces ie wood floors ,inthe corner, glass top etc the vents on the back of the tv allow for proper cooling of the lamp at shutoff so it doesnt shatter the tube its kinda like annealing glass its designed to extend the life of the lamp .... which im sure youve priced call toshiba and tell them your lamp is bad right now and get a new one for an emergency ( warranty if you can do it ) they are also improved this product is known to have short bulb life sometimes the zinging noise you hear is indicative of a bad color wheel in the light engine which would require replacement ( not cheap) toshiba will not piece out the color wheel assembly individually
