I really knew that the Plasma was going bad, just did not know what was causing it. I Once it was down I open it it and checked for the problem and I soon found it was the lower buffer had failed one of the ICs had shorted. I started looking for replacements on the net and came across your Repair shop and Blog. Very intersting, it isn't rocket science. My set was a 42" Plasma I brought from Dell, I like the styling of the set and would like to restore it back to working order, so I will be ordering from you guys soon.Robert Zenonhttps://www.blogger.com/profile/04141702352955158367noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-91041610850924689682011-11-19T18:49:25.848-06:002011-11-19T18:49:25.848-06:00Thank you for this great information, it's bee...Thank you for this great information, it's been a tremendous help.<br /><br />Have you any experience putting different buffer boards in the 3-board systems? The upper/lower buffer boards are running about $160 total, but this single-board is only $50! http://www.shopjimmy.com/philips-996500036819-y-scan-drive.htm<br /><br />It looks like the connectors are the same, but they're slightly offset... I could likely rig something with point-to-point soldering, assuming the signals are the same... (I'll verify the pinout when I order it...)<br /><br />Another question: Have you ever seen a plasma with an undulating red blob in the center of the screen? It undulates outward almost filling the full screen. There're a few random blue and green pixels. It's almost like it's not receiving enough power for the whole display... but there's nothing recognizable in the blob, either. Could that be a failure in the Z-sus? Voltages seem correct, and I don't see any blown capacitors... but I couldn't get a whole lot of testing in before my Y-buffers shorted and took out yet another of the 7 parallel FETs in the Y-sus board.<br /><br />Also, a note about your site: When you comment-as a Google account, it refreshes the screen with one of those text images ("Captcha"?)... but the form is cut-off by the adds at the bottom of the screen!Unknownhttps://www.blogger.com/profile/18308794306303894175noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-35030838100146301812011-05-29T21:23:23.482-05:002011-05-29T21:23:23.482-05:00With my ph-42t7 it has been working great for almo...With my ph-42t7 it has been working great for almost 4 years and all of a sudden starting this week periodically the bottom half of the screen had no display when turned on but after a minute or so it comes on.<br /><br />any help is much appreciated.Jayhttps://www.blogger.com/profile/17635797228487981883noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-45459562233902841802011-04-02T14:55:41.477-05:002011-04-02T14:55:41.477-05:00if i remove the buffers my tv set stay on (green l...if i remove the buffers my tv set stay on (green led), no blown fuses or apparent damage to parts in YSUS, it mean my YSUS board is good?<br /><br />any help will be apreciated.<br /><br />best regards.Unknownhttps://www.blogger.com/profile/16498380262988738263noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-28347710029594367592011-03-21T21:50:03.453-05:002011-03-21T21:50:03.453-05:00I have these buffers in my tv.upper confirmed bad....I have these buffers in my tv.upper confirmed bad. After removing them I still had no voltage on vscan. The voltage no longer fluctuates just stays 0. Also similar symptoms to log with the hot resistors. After removing the connector to the logic board, vsync returns at -180 v and the resistors loose their heat. Does this indicate the logic board is bad? Any response/ hint would be helpful.Tyehttps://www.blogger.com/profile/16515735927405936913noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-76987640984935658012011-03-21T21:44:29.809-05:002011-03-21T21:44:29.809-05:00This comment has been removed by the author.Tyehttps://www.blogger.com/profile/16515735927405936913noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-85127315085953425102011-02-05T10:40:23.498-06:002011-02-05T10:40:23.498-06:00You can run any plasma TV without YSUS buffers.

There'll be no picture, of course, but there is no risk to the YSUS.<br /><br />In this particular case, if you have a shorted buffer you most likely also have a shorted YSUS so trying to run it will likely cause the TV to shut itself off.Bobby Kolevhttps://www.blogger.com/profile/10664410697637213341noreply@blogger.comtag:blogger.com,1999:blog-5753885781627227255.post-42793347883938648572011-01-31T12:27:44.363-06:002011-01-31T12:27:44.363-06:00I have a Magnavox 42MF230a/237 with the same y-sus...I have a Magnavox 42MF230a/237 with the same y-sus and buffers mentioned in this and earlier article. <br />My buffers tested bad. I cannot read the -190 vdc VScan (it jumps around wildly) on the power board while cable connected to the y-sus board. With the cable disconnected it reads fine. No apparent bad caps on any board.<br /><br />My Y-sus board has a good IC by indication of your test reference. I have 2 very hot resistors (R5098 & R5099). I assume the bad buffers are causing this but am unsure if maybe I have other bad components under the closest heatsink causing this. <br /><br />Without disclosing too much competitive information, could you tell me whether the Y-sus is definately toasted or if I will toast it by powering it on without the buffers connected. Thanks for the excellent info you have already given me!

It was working one minute,no picture or sound the next. Same D12V error and I can get sound if I unplug the Y main board. The question I have is it possible it is only the Y main board and can I check by unplugging the buffer boards. As with just the Y main board, with no buffer boards the unit still has the error light, no pic, no sound. Former bench tech on consumer goods but before plasma and lcd came out. I Work for the local government in Kentucky and repair budget is tight. Have a good but cheap source for all three boards if that is what it takes or to be safe.
