How To Repair A Failed Philips/Samsung/JVC Plasma TV

Another landfill rescue; this one was in the process of being loaded onto the truck that takes electronics to the scrapyard. I discovered this model is particularly troublesome, but repairs can be made for around $150. Based on an earlier Samsung plasma engine, these typically blow through Y-sustain boards, which results in failed upper and lower buffer boards (in my case, the y-sus was spared). Legend has it, if you complain loudly enough to Philips, you might be compensated for the cost of a new television, but you didn't hear it from me *wink wink*. This TV was a 2006 model 42PF7320A, and the symptom was horizontal lines and snow throughout the picture.

I am looking for discontinued spare parts for Philips plasma TVs. Where can I find the original circuit board for older Philips TV, ideally manufactured before 2007, so I can pull out the spare part? Thanks

@intellitektumi dunno. I have a few parts for this specific TV, send me a private message and we'll talk.

Thank you for showing us this video, i have the same exact 42" phillips plasma but mine has the ambilight feature, do you think ill have any issues with that or is this pretty much the same process for mine? Also, where is the best and/or cheapest place to purchase these buffer boards? Are the buffer boards the same as a "Y board" ive heard mention in other videos? Thanks!

@izzyiskool Wow! Those Ambilight models were recalled for fire hazard reasons... I'd check with Philips to determine if your set isn't still covered. The buffer boards plug into the Y-SUS board, your set has two buffer boards and one Y-SUS board. Typically, both boards AND the Y-SUS should be replaced at the same time. You can often find these parts on Ebay.

Wonder if this would work on a CRT-based Toshiba ColorStream, with 2 inches of horizontal lines at the top of the display, for about 3 minutes after you turn it on. Gets really annoying, but it's not mine...

@CarnelProd666 CRT sets are nothing like Plasma or LCD sets when it comes to how a picture is generated and produced; they use entirely different components and techniques.

@bbishoppcm Hi i no this post is a bit old now, but just wondering if you can help me. I have a 42in plasma screen from samsung its about 5 years old now. When i turn on the tv all i get is the screen flashing over and over black sometimes a few different colours. Would this be a problem with the buffer boards you are talking about or could it be a resistor problem. Any help will be most appreciated Thanx Matt

Hello, good video man. YOu know, I own a 50 inch Phillips (ambilight) as well and I need to replace the upper lower buffers and the y sus board. where can i find/get these guys... It's kind of hard.

I have a Magnavox 42MF231D/37 that has two blown capacitors on the Y-Main and a burnt y-upper board. i hear is two clicks when turning on, no picture. I am going to replace the y-upper buffer and the two caps... can you think of anything else that i should check that could cause this stuff to happen? You know... I don't want to spend all this money and have it be something else that caused the caps to vent and then the y-upper to burn....

I have a similar TV (has the ambilight, and no recall), and the top horizontal half has now a 4inch black line , should I buy 1 buffer board and 1 Y SUS board?

Thanks!!!

@bbishoppcm , my has no picture, no sound. i have replaced 2 popular know failed caps no avial, then replaced the whole power supply still no avail. TV will respond to ON/OFF with remote + green LED will flash when hit the remote. Both buffer boards were replaced 3 yrs ago. Do u think is the Y-Main board? Any ideas...?

[izzyiskool]

@bbishoppcm I just checked my Seriel number, model number and buildate and mine does NOT fall under the recall unfortunately. Mine was built nov 2005. Well my TV does the exact same thing you've posted a video of, and for sure the bottom does it but the top also kinda does it too, moreso in the center to upper center area so im thinking about getting both buffer boards. Should i also get the Y board? Mine doesn't seem to be making the flaky white dots... yet.
