Question about LG 50PX5D 50 in. Plasma HDTV

Humming noise Is it normal for our 50" plasma hdtv to have a humming noise? We've had it a year and about a month ago it started humming. It hangs on the wall and was install by the Best Buy techs. We don't have hd cable, just normal comcast cable going through it.

Re: Humming noise

Most times a humming noise in a Plasma tv is associated with high altitude. If you live over 3500 ft. and when you first turn on the unit is has a slight buzz and it gets worse as it warms up then you have what is referred to as high altitude sickness. You shoul contact the manufacture with this problem and the should exchange the unit with one tested for proper operation at high altitude. If you do not live at high altitude then there is a problem in the unit that should be diagnosed.

NS-PDP50HD-09 Insignia 50" plasma HDTV I bought it from Best Buy about 2 years ago. About a month ago, it started turning off by itself, and now no picture or sound comes on altogether. The power light...

Since the power light is on the standby circuit is working fine and it is cutting up on powering the circuits, so either it could be a safety trigger or a failer. you will need to cross check by omission flow charting to find out if it is the Main power or the drive power.Check for dry joints or loose connection by tapping the main board to see any reaction to start up. good luck

Humming from back of tv

sounds like your powerboard, you can try a cheap fix by putting a small fan behind the tv on low and see if that helps. Also I would not settle for this and call in the warranty and get it fixed while you can.

Black screen

You have a cracked panel and the gasses inside have escaped. The buzzing noize you are hearing the the current flowing throught the panel. It will be cheaper buying a new TV than buying a replacement panel. But if u wanna check out the price look up your model on

No screen display - VIzio 50" Flat screen TV

If you purchased the TV 6 months ago, still under manufacturers warranty. They normally give customers 1 year warranty coverage.
It looks like the main board will have to be replace on this TV or fix to the component level.

Humming/buzzing sound

We usually find this is the cabinet back rattling. To confirm, when this happens turn the volume on the set all the way down and see if the problem is still there. If it is still there the put your hand on the back of the tv and gently press to see if the buzzing goes away. If the sound does go away the cure is to loosen all of the back cabinet screws around the edges of the set and gently push on the back as you tighten the screw. tighten the screw in an order much like you would tighten the lug nuts on a tire. in other words thighten the top left screw, then the bottom right screw and kepp alternating as yougo around the dabinet back untill they are all tight.
