Samsung hlp6163w dlp there is a buzzing sometimes after the tv is on. When you shut the tv off the picture goes out but the buzzing continues for a few seconds more then shuts off ?


Fault with its main board itself. After a duration of proper working, the horizontal oscillation shuts off, while the main power supply voltage is there, for some time, [that is why you hear the buzzing sound; generated at its SMPS transformer]. A loose solder terminal at tthe main board can cause this. Even though, there might be some other reason too. The troubleshoot to this kind of fault is, somewhat skilled one. It will take some time to reach the exact fault point; even for an experienced service technician. It will be best to seek assistance from any experienced service technician. Electro help

The tv made poping sound & it lost the picture but the sound was ok, their is buzzing sound coming from inside the tv, after about a min. the set turn off & red light stays on. reset tv, same...


This model is prone to a lot of problems to the point where a year or so ago they offered a chassis replacement on an exchange basis.

I would with rear cover removed try to localize first where the sound or buzz is coming from: The ballast? the Light engine? The power supply?

I can help but as I said this model has a LOT of chronic problems.

My TV has developed a loud buzzing sound. Tha lamp seems to work ok, and the sound seems to be emanating from the fan, which is working. Fan or color wheel? The picture comes on, but seems to deteriorate...


Color wheel is bad call Encompass Parts or visit their website and if they dont have one in stock at least you will know what your Part number is ! then you can Look it up on E-Bay I have found parts there cheaper 1-800-638-3328 or try UED 1-800-648-6657

No picture, hear sound, television will shut off after a few seconds.


Lamp life is only a few thousand hours. Hopefully its only the lamp that made to noise. Don't turn on again until lamp is replaced.

Loud humming or high pitch buzzing noise coming from my rca dlp tv 50 inch


I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.

My 60" lcd projection tv wont turn on sometimes and throws a lamp light, and if i watch tv for a while and turn it off it wont turn back on and throws the red lamp light


The buzzing sound you most likely hear is the ballast trying to fire up the lamp. I would say replace the lamp and yes they can act up at will. If this is the first lamp replacement ever then you are doing good.
