    I did not test any inputs or voltages. Not quite sure where to start on that note as well. I had tech from geed squad run a quick look over it, as he happend to be next door, and he didn't do any testing, he did say that he never saw one do this before and can only suggest it may be either the panel or the micro board, but not sure. how would i go about testing the voltages and inputs?

    How are the panel voltages? Which inputs have you tested?

On the back of th panel are list Vs, Va voltages. Find the test point on the power brd. Labeled on one of the connectors. See if voltages match. If they are slightly off find coresponding trimmers and adj. if way off disconnect x and y sustain boards from power board. if stays low then replaced power board. if it is normal with x,y disconnected then one of sustain boards. if voltages all ok suspect panel. ry checking other inuts first to see if this is a vseo problem or not.

I have a Samsung Plasma TV (SPS4243X/XAA). When I turn the TV on, the picture fades to black after about 1 minute. I can turn the TV off and back on and it fades after about 5 seconds. What is wrong?


Fault to its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Great picture, no sound


There is most likely a faulty capacitor or resistor on circuit board for the audio ouputs. It will have to be tested to find faulty capacitor or resistor

Samsung Plasma Lines and Colors on Screen


first is it still under warranty through the manufacturer samsung is verry well with wanrranties
It sounds like it is most likely the plasma gas itself and in that case it would cost way more than what you could purchase another one for.
by the time you have a tech come out and fix the plasma gas tube itself yould be looking well over 1000

Samsung hpr4252x perfect picture in


You have a burn in problem from watching widescreen movies.If you have access to a signal generator or tv setup disc run a perfectly white screen on the plasma for about 30 min.This should help even out the pixels on the display.
