I have a hp5060n 50in plasma tv,the left speaker makes a loud noise.can i use the inside speaker from a 4260n plasma tv with it?


Good morning there from here
According to my information if the noise comes on and off in connetion with tv turned on and off, the noise is due to a change in ambient humitity or temerature. Then there is nothing wrong with the TV,just wait till the weather changes.
I wouldalsocheck the AUDIO settings on the TV .
hope all goes well
