If you have a cable box connected to the TV disconnect that from the TV and see if the issue goes away. If it does then I suspect there is A.C> leakage in the cable box or somewhere in their wiring. Please take a few moments to rate my answer. Thanks...

My Samsung Plasma TV just made a popping sound and then shut off. It will not come back on.


Popping sounds from plasma tv's are almost always caused by a blown sustain board ( Y,Z, or both). It could be a main power supply also. Have a technician check it out.

Samsung plasma tv white screen repair


You have a shorted main board in the TV, it is more expensive to repair this than to replace the TV at current TV flat screen prices. Also I suggest the brand Vizio, it has the bet reliability ratings of any brand hands down.

Samsung plasma tv humming


apply slight pressure to various parts of the back cover and see if it stops. The HP-T5084 model has a humming problem as well. It comes from two cheesy ground clips that "ground" the metal back cover.

My DLP HL-P5663W TVhas developed a hum similar to an AC 60-cycle hum. This is unrelated to any speaker, and seems to emante from the vicinity of the lamp. Have replaced the lamp, but hum persists. What is...


This may be an issue with the color wheel. My thoughts is that the motor that runs the color wheel is going out. May be time to get it in to a Good TV Repair Service Shop.

Scrolling line


Question. Are the scrolling lines horizontal?
If so that is called 60 cycle Hum Bar and is a result of the following:
1. Bad grounding of the cable system.
2.Bad cable box. This a common problem with cable boxes.
3.If you are using Component cables from the cable box to the tv then the Component cables might be bad. Try using another set of Component cables. If that does not work then you need to call the Cable co. to come out and check their system and make sure that the cable tech brings out another cable box to try out. There is no problem with the set.
