I googled the part numbers and ended up on a website that allowed me to purchase the buffer cards for around $120.00 each. The Y sustain card was purchased of of e-bay for $80.00 including shipping. I think that I got lucky with the Y sustain card.

It took a lot of searching to find the cards.

Each card had multiple part numbers on them.

LJ41-02759A = LJ92-01200A = Y Sustain
LJ41-02760A = LJ92-01202A = Y Buffer Upper
LJ41-02761A = LJ92-01203A = Y Buffer Lower

I searched today for the same part numbers and they were priced much higher.

The site was a Vance Baldwin parts store which is where philips must be distributing their replacement parts.

The Ymain Board is out if you have the back of the tv exposed disconnect the ymain board and then plug in the tv set and turn it on. the light should remain green and no longer flash. If this happens the Y main and upper and lower buffer boards should be replaced

Most likely the YSCAN UPPER board and/or YSCAN LOWER Board also gone. Your new YSUS board may damage again if you don't replace the bad YSCAN boards. Try to replace the three boards together and then to verify which boards are bad one by one. Good luck.

After you remove the back cover inspect the power supply board for swollen or bulging capacitors. Pull and check any capacitors that you suspect to be swollen. Next, look for a sticker in the upper right hand side of the TV set. Use the values you find on the sticker to calibrate the voltages on the power supply board.

Phillips TV- Plasma Model #42PF7220A/37


A tech will need to come out. When the tech do come out have him unplug the Y main and see if the led goes solid greem if it does have them replace the Ymain and the Y upper/lower boards. Most likely that will be the problem.

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.
