@Joh1Aerilon Bummer, Murphy’s law. At least mine is still usable.
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!!
i love the end
Thumbs up if you:

The thing you see around the chip-contacts (Plasma chips) are there to make it difficult to
tap signals on the pins of the IC. This assures that high-tech guys have a difficult time capturing a movie which was not supposed to be copied by it’s studio, since from those pins, you can actually capture the whole movie in excellent quality (thus bypassing HDCP protection)…
Analog devices chip is for decoding HDMI and more importantly, HDCP (brought to you by big-brothers in Warner Bros, Disney, RIAA, and so on…)
Dave: Is that a light bulb there at 4:45?
i would never ever buy a plasma just because of this reason they dont last long and really when it come to the end of the day we buy a tv for it to last for a long time not 2 year that just bullshit ,i hope u fixed the tv or better yet i hope u got a newer tv i would eather go for a LED samsung i would go for or LCD but NEVER NEVER plasma EVERRRRR !!!!!!!!! good luck buddy .
A model number would be a great help? Every models different.
ROFL Very funny
Man that sort of thing drives me nuts.
You’re right about the location of the problem – it is at the ribbon or inside.
I’m sorta crazy and would likely have deconstructed the plasma assembly as to see if the ribbon cable was replaceable.
Worst case scenario you have yourself a boat load of parts to sell on ebay.
Thanks much for taking the time to share – I’m sorry for your loss!!
you can fix everything with duck tape
Good Job Dave ! :)
@TheEPROM9 I used to work at an electronics repair workshop. You wouldn’t believe how many CRTs were thrown out. Often it was because the owner didn’t want to pay for it to be fixed but there were many that just couldn’t be fixed. For example, CRT manufacturers never used a standard set of flyback transformers so unless someone like HR makes the specific transformer you are looking for, the most common CRT fault just can’t be fixed.
I used to recommend Panasonic to a lot of people…not anymore.
@davidsfc9 I hate it! I did a drive time rant on this topic too.
It seems to be a worlwide cliché, that every EE engineer knows how to repair the tv’s XD
I know how you feel when people ask you to fix stuff. While I’m not an electronics engineer, electronics is my hobby and I have been trained in computer repair as I am studying a computing course. The modern stuff is just not built to be fixed… so most of the time it is imposible to fix.
You can Imagen Panasonic sitting in their control room with evil smiles on there faces as the activate the self destruct chip when the worenty runs out with a big red button.
!
Stick to CRT, they refuse to die. The only way to kill them is destroy the tube and that’s not easy un less you open it up. Shame the new stuff is built so badly, it had so much potential. Your new scope just proves no matter how much you spend, its all shit.

Love this guy! HEY he fixed it after all! just needed a little duck-tape!!!
Love this guy!
@heroineworshipper No, a heat gun didn’t fix it.
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.
