My mitsubishi tv wont show a picture but it will make sounds


Hello, there are several things, a bad ballast board that provides the lamp with it's voltage to run it. Also a bad power supply can cause it. a bad Color Wheel will also stop it from coming on, if you heard a high pitched squealing sound before it went out, the color wheel would be my best guess.....tks

Tv samsung hls4266w all light are blinking replace the blud small fan and large fan running


Sounds like a bad color wheel----remove lamp---the wheel faces it--look for missing pieces or the wheel shattered---these are known for the wheel making a loud high pitched sound or even a grinding sound if the wheel shatters.

if wheel bad You Tube has video instructions for replacing it---seen several people able to do this themselves in about a hour. Google the model number to ("color wheel") to locate a replacement on the internet.10_24_2012_4_08_47_pm.jpg

Wavy lines on the screen and a high pitch sound sometimes.


If you have a Dlp it might be the color wheel.The color wheel is in charge of creating the colors and when it's bad you'll hear humming,buzzing,whirling sounds.

Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion


If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..
