Loved how you "fixed" the TV. I got myself a Panasonic Plasma Viera and it presented the same issue (and got the same reply from the techs: replace the plasma screen) but sadly I can't fix it like you did. The black colum is right in the center of the screen.

And, of course, the Panasonic call center did the obvious: "this happens. We can't do anything if warranty is over".

Panasonic: Never Again!!

@Joh1Aerilon Bummer, Murphy's law. At least mine is still usable.

It seems to be a worlwide cliché, that every EE engineer knows how to repair the tv's XD

[EEVblog]

@davidsfc9 I hate it! I did a drive time rant on this topic too.

Why would something as big & heavy as a plasma TV need flex cable mounted chips? It probably was a loose solder joint to the flex cable that a heat gun could have fixed. Enough temperature cycles could have done it.

@heroineworshipper No, a heat gun didn't fix it.

@Lavinco Heat gun doesn't work. The elevated voice is called a High Rising Terminal, it's natural.

@12344richard Unfortunately, Samsungs have a higher failure rate than Pannys.

I love your T'shirt - from Mythbusters?

10:26 Those turquoise caps are Rubycon RX30 Industrial grade / high temperature caps, rated for 5000hours at 130°C (yes.. 130)

In other words: it doesn't matter that they're wedged in between the heatsinks. They obviously used really hich quality caps throughout the whole thing, unlike a lot of other brands like Samsung and LG, which keep using chinese garbage caps (Capxon, Samwha, Sam Young, Su'scon, ...) that fail after the warranty ran out to make Average joe go buy a new TV or whatever..

Hahaha, really interesting and funny video.

I liked the end !

@davidsfc9 nope just they don't want the headache for your tv....or any one's for that matter, I should know...i live on repairing these under budget pieces of shit...don't get me wrong ...i like capitalism...fuck that, and fuck them who want a dollar more in there pocket, just to spend it on a hooker, and then they say they have an difficult family situation...fuck them...fucking animals...

35 dislikes are probably from people who have some connection to "panasonic"

[wowerman]

i would do exactly same thing,mask it with some plastic strip

Don't see how its worse than Samsung plasmas blowing their power supply or the LG pop of death. I don't know if it is really planned, I think it is just poor design to speed up manufacturing. The manufacturing standards are about the same on all of them. I'm fixing a pop of death Maxent made by LG at the moment, Y-SUS board on this one, got two slightly domed caps on the PS I'll replace when its open. No name caps & heat is a bad thing. I'd honestly be surprised if any 2007 era Samsungs work now

Calm down man!!!

@EEVblog I agree. A girl once asked me to fix her laptop because it wouldn't turn on. NO, I can't fix your laptop that you probably spilled beer on!
