samsung plasma tv not working, wouldn't turn on, FIXED, repair, diy

I am NOT a TV repairman. This video involves high voltages that can KILL you. Please do not attempt this stuff unless you are comfortable working with high voltages, capacitors, and plugging things into the wall outlets!

This is my fix for a friend's Samsung Plasma Smart TV. One day it wouldn't turn on. The RED LED on the front of the unit just blinked, and he could hear clicky sounds from the tv, but no picture. It wouldn't power up. So he gave me the TV and bought a new one. This one is around $3k or so... or at least it was. Basically Samsung's best of the best....

Here is the link to the video that inspired the fix....

I'm sure this video will help other models, and help troubleshoot other brands of TV's.

Thanks for watching!

part that was replaced: Samsung BN96-14977A X-Main Board LJ41-08415A LJ92-01713B (Y)

NOTE: if what I have posted as helped you out enough to justify paying me back in some way, this is the best way I can think of... my amazon wish list! this products here will help support future vids! thanks in advance!

update: 10/2017. this tv has come back into my possession. it stopped working again, only this time, it TOTALLY stopped working. I suspected the power supply, so I swapped that out for an ebay power supply. no dice. swapped a few other boards ( i was guessing ... no good) ...no go. Months later I revisited it and swapped the power supply with a new one off ebay. PERFECT. I know this is guess and check, so if you want to check out a channel that isn't about guess and check, please check out 12voltvids channel here on youtube. He does much more in depth component level fixes.

For someone who isn't trained in electronics you did an excellent job and found the fault logically. Getting a little help when you needed it rather than giving up is the way to go.

This is honestly A great video with no nonsense talking and the right amount of content. You get right to the point and don’t spend the first five minutes introducing your channel and plugging yourself. Thank you for helping people and taking the time to do this. Humanity thanks you

I like videos straight to the point without the mumbo jumbo capacitor flux bull s..t,
Great job! Now, I am going to take the tv out the trash and try to fix it.

I just wanted to say thank you so much for taking the time to post this video....it saved me at least $500. I used your technique to troubleshoot which board was making my Samsung plasma click and not turn on and although it wasn't the x or y axis board but the power board itself. No bulging capacitors but looked on the website for used parts and new power board for $42 shipped to my house fixed the tv again and don't listen to any of those idiots who commented negatively above me....you saved me a whole bunch of money and time. If I could send you a bottle a whiskey I would!!! Thanks for the help

[altomic]

[kjheuston]

[uuucuz]

This video saved me at least $300-400. Thank you thank you

Maaaan!!! I have a 50" Samsung with the same problem and with the same procedure I found the problem. it was really helpful. Thanks to you and the other person who posted the video similar to yours.

Hello            Good job...aslo  a quick good test is to  check the VS, VA on the power supply.5v standby.sometimes if the y-sus board goes it takes out the x-sus sametime pain!!! I`ve just fix a 43" plasma set....bad power supply, x-sus board both bad...change both boards for £20.00 cheap good fix....I find plasma sets gets some hot....

[somikhem]

Thank you sir! This was very helpful to fix my pn50B450B1d.

Anthony McKeller, can't seem to reply directly, so hopefully this helps, sounds like either your power supply is bad or your av board, again, i'm not an expert on this, but it may be worth playing "parts darts" ...throw some parts at it and see if it improves....2 boards, can't be all that expensive on ebay....best of luck

The subwoofers lining the platform beneath the couch! I bet that system RUMBLES. Nice

Still have my Sharp 40" CRT and never had such problems. I see so many problems on the internet with all the new type TV's, seem more than for the old CRT's. Samsung TV's seem to have a higher complaint rate across internet than other makers, but maybe they sell more of them too. We had Samsung VCR's that lasted almost a decade each, so wonder if their quality control has lagged since those days?

@Matthew Olson, I have 42inch plasma with the clicky clicky, I pulled x and y separately with no change, when I pull the board with the aux and hdmi's I get nothing at all, do you think it's the power board then?

[Ochibason]

Did you say there was a link to where you got some more info?? Hows the TV running now??

[michaelgossett]

Thank you for the information.
You saved me a great deal of

I'm having a similar issue with an LG plasma. I've got audio but no picture, a black screen. I Had somebody check the Y Sus main board. They said its good. I ordered an upper buffer board and installed it but still have the same problem. I'm wondering if I should also order the lower buffer board. Do you think a bad lower buffer board would cause this issue? Great content, thank you

Hi i have the samsung PN64D550 i bought way back in 2008 and was perfectly until a few days when then sometimes it won't turn on just the red light and click click but if i unplug the power a few time it starts and comes back to life. Sometimes it works all day sometime it works for an hour then i have to unplug replug in again. Sometimes it will turn off while I'm watching something.

Do you think mine needs a x-main board ? Thanks )
