Samsung PN43F4500 Plasma Dead repaired

[@BP-bx6si]

I just returned this tv to my neighbor who is on a disability pension and couldn't afford a new set .He is absolutely thrilled to say the least. Many thanks to 12voltvids for saving it from the scrappers, and making this informative video to help others save their tv's . The picture is absolutely fantastic!

[@12voltvids]

You're welcome. I love the plasma sets for their picture quality. Even though this is a 720 set, the picture is still excellent.

[@sinecure1]

Great instructions! My TV is mounted outside, and while my testing didn't determine the board was bad, I guess the action of unplugging and re-plugging all ribbon cables gave better contact, and now it is working again!

[@DAVIDGREGORYKERR]

Thank goodness you were able to get the replacement board at last, BTW if you are after a output transformer for the Electrohome radio then get the output transformer that is used in valve based guitar amps.

[@rscelectrical7091]

Nice job buddy, glad you were able to get the set sorted.

[@zx8401ztv]

Thank god they sent a good board this time, it's bloody annoying when suppliers are sloppy. Shame the owner bought a psu, but thats guessing, some you win.....

[@UnkyjoesPlayhouse]

I am old school as well, repair vs replace, alas the world has changed...I watch a guy that does board level repairs for Mac Laptops, and he is always ranting about how Apple makes it harder and harder to repair their products. A skilled electronics pro at your fingertips used to be as important as a good plumber, now we just throw stuff away :( Nice repair.

[@FindLiberty]

COMPONENT level repairs, not board level. Probably, that guy you watch is Louis Rossmann. He is very helpful and shows exactly how repairs are made. I love his "rants". Louis sells tools/parts/supplies too. _(he "hates" Apple repair policy/parts/prices/way they deal with customers, but he loves the fact that Apple makes his business possible/profitable. Apple owners love him for coming to their rescue!)_

[@12voltvids]

Got news for you, I do component level repairs. Go look at the Sony XBR6 where I TS and replaced the gama correction ship, and all I had was people telling me I should just change the TCON board. I did troubleshoot the board to the actual component and point it out at 2:45, but why waste time changing the chip when the cost of the entire board is so cheap. If the board is not available, or it cost 100.00 or more then sure, but with a readily available board this is the way to do it, and a board replacement is something anyone can do once they know how to test the board and find out which one is the problem. I guarantee you that someone watching this will have the same problem, watch the diagnostic test, find that their board is bad, and replace it and their TV is fixed. I seriously doubt that that the average hobbiest would attempt a SMD IC replace. They will watch the video, and then go and buy the entire board because they do not have the skill or equipment to do it. I don't have a hot air station, or hot plate, or a microscope because this is NOT my business. I used to do this work full time. I left back in 2003 and now work for the phone company spending my days working on copper and fiber optic networks. I only do this work part time now. I try to do it all using common tools that most hobbyists will have on hand.

[@FindLiberty]

U R great 12voltvids, yes I know, not new news to me, I agree 100% . Your repair here was PERFECT ...thanks again for the great tip on testing for shorted chips right at the connectors! _My response was to Unkyjoe's Playhouse who also remembers the good old days: _ _*_Louis Rossmann does SMD *COMPONENT LEVEL_*_ (not board level, as stated) repairs to Mac Laptops since working replacement boards are not available and/or way too expensive; they're almost the cost of buying a new Apple and Apple repair costs are even more of an outrage. And that's Rossmann's main _*_repair_*_ business niche, _thank$ to Apple._

[@UnkyjoesPlayhouse]

Oh I know you do, I have watched most of your vids, Louis "mentioned above" does them as well, he just bitches more during his repairs :)

[@12voltvids]

I have done many component level repairs, and if the board was 100.00 that would be an option, but when the entire board is 18.00 why fuck around changing parts. I did that on my KDL37XBR6, cut the bad gama correction chip out with a razor blade, and stuck a new one in. Why? Because that board was over 100.00 and the chip 1.82.

[@ned8880]

Great info about how to measure the buffer chips. Many thanks.

[@12voltvids]

Will save many people from ordering the wrong board.

[@repairitdontreplaceit]

i replaced a fair few of those ics .. allways need to use silicone over them to avoid them arcing across the pins

[@12voltvids]

Yup, need the silicone because they use high voltage, and will grow tin whiskers and short

[@BeachTechPC]

Hope that residue on the back is leftover from the manufacturing process. Looks more like water or some kind of cleaning solvent though.

[@BlackBullPistol]

I bought a defective PS51F5570 (2013) for dirty cheap, the Panel itself looks without any damage, in the inside it looks almost as this one except the Y sus and Y buffer are separated and also the Power and X are. It also blinks every 4 or 5 seconds and the faulty board is Y sus, it has a blown TPC8407 IC, Q5005, 2 shorted transistors and maybe some more components so I've decided to buy a whole board instead. I hope the board comes next week but I'm also concerned about vertical lines that might appear. If there are some lines than I have to be lucky to have only some unbonded COF ribbon cables on the vertical address board :-)

[@borndifferentnf1]

Did u figure if it was your y man board no this is 3 years old trying figure my tv out im getting the blinking light on my main board so hopefully means my power supply good

[@BlackBullPistol]

@@borndifferentnf1 Yo hey. Yes in my case it was a faulty Y board, after replacing it the TV was working fine. The only issue that I couldn't solve were the vertical colored lines because the panel itself is made low quality. I did not know at the time that many newer Plasma TV's had one and the same problem and that's because manufacturers are cheap mofos. Older Plasma TV's have no Panel problems whatsoever, I have also a Samsung TV from 2007 and has 0 problems. I'm looking into Oled TV's these days cuzz the prices did come down quite extensively :-)

[@borndifferentnf1]

@@BlackBullPistol thanks im trying get my come on lol hopefully not power supply. But im getting a light on control baord and sound if i unplug y baord

[@t0nito]

First YAY!!! :) That defective board you received looked like it had moisture damage on the back (4:54). EDIT: Oh I just realized that was the actual working board, I commented too soon.

[@12voltvids]

I showed the first one (defective) in a separate video.

[@jonmccurley922]

Any chance there is a video removing that power supply? I have the same TV, but I can't figure out those two ribbon connectors. They do not seem to flip up like the board you are working on.

[@nancysmith9487]

Thank you sir for your input

[@upsidediy3945]

2:40 people are thinking the pins or connectors bad, Dave points it's the chip.And I bet a chip pin/ leg is desoldered .

[@staying]

good job look I have one like it already check and there is no short, it can be the source of power

[@shaun9107]

no messing about...... I like that

[@misterredington4581]

[@geojor]

always great, thank you ...

[@mdzacharias]

I think there was a firmware update to help prevent recurrence on these.

[@12voltvids]

Yes, most smart TVs will take the firmware upgrade to fix issues automatically.

[@Kn0wOneNos3]

I'm gonna try the same repair on this same TV a few days from now. I'm concerned I might break a plastic tab in trying to remove either the connector to the power board or the main video board. Any tips on how to safely remove the plugs?

[@12voltvids]

They use a ZIF socket. Lift the release tab and they lift out or slide out easily.

[@Kn0wOneNos3]

@@12voltvids Thanks. I'll keep it in mind.

I have one both hdmi ports not working, hdmi 2 I get red screen , used 3 different hdmi cords and they all work with another tv... any idea on what I should order for a replacement part or how I would check. I have an antenna in and working with it now

[@12voltvids]

HDMI is typically on the main board so that is what you will need.

Could be the buffer board, you need to measure the connectors for shorts. The xmain board wan also cause this fault.

[@marvissteverson1163]

how could I tell or can someone put a camera in my Samsung tv.....

[@zulkarnainkarim]

what the board is called sir?

[@12voltvids]

This is the Y-Sustain board on this set. It is a combination Y Sustain / y buffer board. On some sets they have a separate y sustain, and buffer boards, and older sets had an upper buffer and lower buffer in addition to the Y sustain.

them boards are expensive

[@BP-bx6si]

Total cost of the board and shipping was around $22.00 US dollars

[@aqib2000]

I wouldn't classify this as an actual repair

[@BP-bx6si]

I would say it's repaired. When I brought this tv to Dave it wasn't working, and now it does, and he made it work by replacing a faulty component that cost me a mere $17.00 . Do you think he should have spent several hours trying to replace the shorted IC at a minimum $100.00 an hour ? I can get a working 43 inch plasma off of Craigslist right now for $150 Canadian. Do the math.

[@12voltvids]

We just found the troll!

[@uK8cvPAq]

Nonsense, he took a broken item and turned it into a working appliance. You don't need to bring out the soldering iron for everything.

[@aqib2000]

I would call this a fix, not a repair as per my original comment

[@uK8cvPAq]

The TV was repaired, end of discussion.
