Needs a upper buffer board. Is it hard to fix?


No, easy repair if you know for sure that is the only problem. It is very rare to have just an upper buffer board bad without the Y sustain board being bad also.

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.

1 inch wide stripe across the screen about 5 inches down from top


Some Mfg's sell them by the pair ( upper+lower ) plus the Y main board. This is not uncommon, I see it everyday. Even tho just the upper went bad there's a good chance it fatigued the Y main and you'll have a problem again down the road, so they make it up as a Kit with all 3. I just did a Samsung 42" that cost the customer 550.00 but it's better than the other way and the customer was happy with it.

JVC PD-42DX6BJ plasma 42 inch black horizontal lines over the pic


Here's a link to order the original the JVC upper Y-buffer board and lower Y-buffer board for this model from a major parts distributor if needed:


JVC "PD-42DX6" Replacement Part Upper Y - Buffer Board (LJ41-02760A)

JVC "PD-42DX6" Replacement Part Lower Y - Buffer Board (LJ41-02761A)

Based on the symptoms: It is possible that the Y-buffers are faulty, which may require the replacement of the Y-sus board as well. You may want to get a local technician to diagnose the unit and provide a second opinion.

Phillips 42 inch Plasma -Screen Issues!!!


intermittent loss of picture on either bottom or top half of screen is specific to y buffer boards located on left side of screen going from top to bottom when looking at back of tv. the y lower buffer would be the board to replace to resolve the loss of bottom half of picture. if the top half also is going out intermittently could tied to upper buffer as well but just a note the y main board to right of these buffers drives those two boards so in some cases could also be part of the problem. if only bottom half is affected i would recommend replacing lower buffer only

42" Sanyo HD Plasma TV (Model DP42746)


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

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.
