I have an Lg Model RU-52SZ51D Projection TV. Just recently I have had problem #2 with this TV. The first time it was under warranty, now it is not. The problem now is that when I turn on the TV, the left light stays red (to show power)and then flashes to yellow or green as usual. But now the screen remains black and there is a humming, vibrating, buzzing noise coming from the TV. The other display lights do not come on at all. Any help would be greatly appreciated. ```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````
this is either your ballast circuit or color wheel is gone bad (stuck). ballast is more of a fiying noise and color wheel is a ticking noise.
Thank you for taking the time. Are these easy for an ameteur to replace?
