Re: we have samsung 50 inch plasma tv, we have only half...

I have a Phillips 50 inch Plasma. About two months out of warranty the top half of the screen would go black. Sometimes when we tapped on the back behind the upper right hand corner the picture would return. I did some research online and found that there is a Main Y sustain board (much like a mother board in a computer) and connected to that board is a upper Y Buffer board and a Lower Y buffer board. According to my research these boards seem to be the source of the problem. I am assuming that the upper buffer controls the top half of my screen and the lower controls the bottom. I removed the back of my TV (about 50 small screws) and searched for these parts by part number. Surprisingly all of the parts in my Phillips are made by Samsung. I found the parts on ebay at I decided to try replacing the upper Y buffer first. I ordered it from shopjimmy for about 100.00. When I received the part I started to remove my upper Y buffer and realized that the new part was slightly different. The part number was the same but the REV. number was slightly different. The new part was missing a small white connector that connects the upper buffer to the lower buffer. I sent it back for an exchange for the right part with no problem. Ok so here is the interesting piece of this little adventure. When I started to remove my upper Y buffer I removed the screws and started to pull on it to loosen it. When I noticed that I had the wrong part I pushed it back into place and put the screws back . My TV has worked perfectly since I did that, with my original part. It has only been about two months, but if you are in the same situation it might be worth a try.

I have a 50 inch samsung plasma tv that i think

You would need to purchase a complete new screen as it is not practical or economic to have this done. I would suspect your fault could be a poor connection from the buffer board to that section of the screen or most likely, as you state, the screen is at fault. It is now just as reasonable to buy a new TV than to have the screen replaced

50 inch samsung plasma that is 3 years old occassionally gets a black bar across top half of the screen. is this tv done?

not necessarily, sometimes the connectors that feed the screen get old and dirty

If you have some electronic skills, open the TV and clean the connectors around where you see the symptoms and you may have a good chance to get if fix by doing that...

If you talking about on one screen, you cant. BUT you can buy a TV card for your computer so that it will have a built in TV. so you can theoretically have split screen TV and computer. But what your thinking off only works on 2 or more player games consoles

Try to replace the YSCAN board. If not fix it, then it's the PDP Panel failure.
