Question about Samsung Televison & Video

Open Question

Samsung Plasma Tv with screen problems, not lines or bars, but spotty locations that are working.

I can see some menu come up in patches while most of the screen is dark. No reason to believe lcd has been damaged, as it just started having problem after working. probable board suggestions to test? Model PN50B550T2FXZA. I can upload example pictures of screen if there is a way to do so.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

My samsung PN42A450 42" plasma tv started showing


You have problem with the screen board this is located on the top and corner of your screen. The slight solution to do this is try resetting the connector on the main board and the screen board and the screen. it might works or not. Or re-soldered the part on the screen. If the symptoms look for service personnel to do it for you.

I have a white bar on the right side of the screen.


This is caused by either a bad address board (low $) or a bad plasma panel (high $). The only way to know is to replace the corresponding address board and see if it repairs the line. Hope this helps.
