SOURCE: we have samsung 50 inch plasma tv, we have only half a screen

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 shopjimmy.com. 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.

SOURCE: Samsung Plasma 42" TV - 2006

Hi, this is quite a common problem for plasma screens and LCD screens. The fluroscent backlight is more than likely faulty and would need replacing. The best thing to do is to take it to a service centre because there are no user servicable parts inside the plasma.

SOURCE: Samsung Plasma TV have sound but no picture

G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further

SOURCE: error diffusion on Samsung 50" PLASMA TV

Yes the diffusion problem on your tv is due to the pdp panel aging. What you can try is readjusting the VSCAN voltage, there is a test point marked VSCAN using a DVM you can first check the voltage, should be around -- 190 turn the adjustment counter clockwise this should reduce the voltage, watcthing the picture turn control untill the sparkling pixels stop. That should do it. The panel is starting to age this may occur again until you can't adjust it out meaning a bad panel.

Wont turn on but tries too come on,power light blinkink


Internal power supply failure. Was there a lightning storm in your area recently or utility work being done recently? This two things usually kill TV's and other electronics with surges when power is restored. If the set is under warranty call the manufacture, if not, call you homeowners insurance agent to see if the damage is covered w/or w.o. deductible. At least you can get something toward repair/replacement costs. Future fix, purchase and install a surge arrestor in your main AC panel for the whole house or buy a power strip with a built in surge filter/protector for your expensive equipment.
