Scott,
Not at all crazy! The Samsung/Akai lines seem to have numerous problems with their Y and Z sustain boards and upper/lower Y driver boards (aka buffers). That and power supplies are generally the largest percentage of the problems in those units. That said, I'm a bit confused looking at the p/n you referenced. I don't see that as being a Samsung number belonging to a Y-sus board. Usually they start with BPxx-xxxxxx..
Lastly, while you might have every ability to replace the Y-sus board if the buffers are bad and you don't replace them you could simply burn up the sustain board when you power it up... Installing the buffers is a bit more complex than the sustain board so be really careful there...\
Good Luck
Bill

IR senor may not be bad. Try using a different remote (universal) and program to TV. If universal remote works and your doesn't, you may need to purchase a remote instead of IR board. If you confirmed that the IR board is bad then replacing the IR board will fix the remote issue. IR board is an easy fix. Just open the back cover out and it's located right in the middle toward the bottom of the TV.

I had the Same issue. on a 50PF9431D/37 set. Many Plasma Set's use a LJ44-00118A PS-505-PH Power supply from Samsung. Known to have this common problem. If you can, or have a friend that can Solder components?. Unplug your set remove the back panel & locate your power supply. It will be the PCB in the center of the set just above the Video/Audio connections. http://www.shopjimmy.com/power-supply-unit-lj44-00118a-from-philips-50mf231d-40.htm. Is a Link to a photo of the PCB. Make a note of the locations of all cable connections then unplug them all. Un-install PCB, Check all Fuse first. I believe their is 5 or 6 of them on the PCB. Then replace the two 3300uf 10v 105C Radial capacitors at C8060 & C8059. Look to see if the Caps are deformed and or split at the top. The location of the caps are in the Lower bottom edge of the PCB. A local shop may Carrie them if not, digi-key has them. Part # http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=493-1754-ND. Total cost was $7 with S/H.

LG 50" plasma PDP50X4 only shows top half of screen, sound and top half of screen work fine....Help!


That's a relatively easy one - you have either upper or lower Y-Sustain buffer board gone bad.

if the last chip of the upper buffer has failed you may get what you get, even that this is a relatively rare type of failure.

The same would happen if the lower buffer is bad although this is again somewhat rare for a failure for those boards.

Either way you need a new buffer board and I'd start with the lower if I were you.

I assume nobody has messed up with the TV because another possible explanation would be the two buffer boards were disconnected from each other.

The best is they are neither too expensive nor hard to replace.

Hope this helps!

Oh, here's a link with something more about those boards although I am not sure it would apply to your particular case...use it as a good educational resource, but don;t expect to have the exact problem described there:

Y-Buffer upper controls top half, Y Buffer lower control bottom have YSUS controls both of those. There is also D, G, E F boards that can split screan. But they to are controlled with the Y-SUS Main.

the problem is the lower buffer board. however getting to it is a pain. you can test by disconnecting the lower buffer, then turning the tv on. it should turn on and you should get picture, but only on the top half of the screen. the lower buffer causes the tv to act up and go into some sort of protection mode. good luck.

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

We have lost a two inch wide black section on the right side of the plasma panel, any ideas


Most likely the lower buffer board " E " needs to be replaced. Right now I'm working on repairing a 42" Samsung plasma HP-R4272. The Service manual for that TV says for trouble shooting for that problem is the lower buffer board " E ".
Best to find the correct Service Manual for your TV over the internet to get the correct part number for replacement. The Service Manual should be less than $20.

Hi Mikshanks,

I had the same problem with my TV. It was a horizontal problem with different shades of color, and black spots. I replaced my Upper & Lower Y-buffer boards. Your Y-sus board should be okay since it still powers on the screen. You should replace the Y-buffers Upper & Lower, and it should work. I hope this helps.

best regards,

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.
