Question about Samsung TXP3275H 32" TV

1 Answer

Excessive voltage coming from television

We have had a Samsung HDTV for a couple of years, and up till now it has worked great. The picture began showing curvature, then started going out, reappearing, going out, etc very rapidly whenever the set was turned on. When the picture would fade out, the audio would get very loud and distorted at the same time. During the days leading up to this event, we would hear loud "popping" noises coming from the set periodically throughout each day. A cable repair tech was here delivering a new HD box, and when hooking up the new cable box, he got shocked mildly. He hooked up some instruments and told us the television set was "pumping out excessive voltage", way beyond normal limits. He said that instead of using the electrical house ground, it was using the cable tv coax to ground. What would cause a television set to "output excess voltage"? What might the fix be, and what kind of costs are we looking at?

Any image (even the unit's menu) is superimposed by couple wide horizontal half-opaque stripes of color sparks

If i am correct in my assumption of what you are trying to say, you are seeing a random pixel discharge. may look kind of like snow. Early on Samsung had us to adjust the different voltages used to drive the panel, but in my experience this rarely worked and the set came back for repair. Later on Samsung began to authorize panel replacements for this problem. If it is in warranty get it to a shop fast, also check you r warranty, some of the plasmas had a longer warranty on the panel part.

White dots appearing on Samsung TV screen and multipling each day

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.
