SOURCE: Samsung 42" Plasma HDTV cable hookup problem

There sould not have been sparks. Check the following: Using a voltmeter check between the cable itself and ground. There should not be any reading (anything less than .1V is normal). Check again between the inner hole of the RF connector and the outside part. Again there should be less than .1V. If you read any voltage at the RF connector, the TV is faulty and should be exchanged. If you read voltage at the cable, have teh cable company check again.

Most likely it sounds like a Logic Board problem. The Logic Board is what controls images on the screen. It's a somewhat expensive part to replace. Maybe in the $200 range. Being that the part isn't cheap, best to have a TV tech come to your house to take a look at the TV to confirm the diagnoses before buying the replacement part.

SOURCE: I have a Samsung Plasma TV (PN50A450) with sound but no picture.

Y board, Y-buffer board, or panel can cause this problem. Anyways, replace the panel shall be good, because those boards will come with the panel.

Hi there,

Just go online to your local Samsung website.

There you will find a Support section and can enter the model of your Plasma TV.

You will then have the option of downloading your User manual for free.


Cheers,

I sometimes get a red fuzz on my plazma tv screen


Several possibilities for this symptom. First, voltage adjustments needed. Second is a YSUS pcb going bad. Third is the Digital Main pcb going bad. The forth and worst possibility is the panel itself going bad.
