    My TV is located in one of my bedrooms, the only electrical apparatus would be a Digital Clock.

Panasonic PT-56LCX66 buzzing noise when i push power


I'm going to take a guess and say that the buzzing noise and burning smell was either a transformer or a blown capacitor (more likely). It's likely that your old lamp was still good and there is a problem at the circuit level.

If you or someone you know is comfortable with electronics, you may want to open it up and take a look. If there is a blown capacitor it will be obvious. Take a look at badcaps.net or Youtube for help on identifying them.

If you don't feel comfortable working on the inside of a TV it's probably time to get a new one. Repairs will not be cheap and they won't be worth it.

Samsung model HLP4663WX/XAA with loud buzzing noise, need to know which part to replace.


See attached photo: you have a bad color wheel----it turns at about 12,000 rpm and bearings in the tiny motor go bad.

High pitched or fan like sound is classic symptom.

The wheel is available on the internet and You Tube has video instructions by model number for replacing it---Google the model number for the part number for your set to locate the part and instructions.

This for most people is a do it yourself job---takes like 45 minutes start to finish.

If color wheel slows too much set will shut down as its speed is monitored and the wheel can even shatter causing shutdown of the set.

I have a Samsung HLP4663wx xaa that I just replaced the color wheel to fix the buzzing noise and then had to replace the lamp after 16541 hours so definately got my moneys worth. Had to remove the jumper...


I would assume you need to replace that ballast. Usually the bulbs out live the bulb's ballast (from previous experience)...I've seen DLPS do this type of thing when the bulbs are slow to turn on due to a new ballast being needed.


Thanks and hope it helps!

Screen goes black and whte and freezes


Does it do it on all connections IE: DVD, Cabe, VCR? if it does than most likely a bad digital board in the TV. If only on one connection you see this then suspect intermittent connections to that device or a bad cable.

Buzzing sound by bulb


be quite sure that it is not the fan physically touching the case; other than that, scope your B+ voltage to the ballast and be certain it is clean;  while it could be that or the lamp itself, it is most probably loose or misaligned case assembley
