I would be interested in your findings of evidence that there is a
planned failure of software due to ESR

I am currently reviving LCD Tv's from a recycling company I work for

It is a shame that these tv's are from 2007-2010 and they died
already.

I recently joined a good forum for repairs it is

Bad caps dot net has many people helping other people repair
electronics it helped me a lot

Most of the tv's and monitors I see have blown apart caps and I think
it is not by chance that they pop

Yes, that is what the civilians call them. In fact that's what it says on the box usually.

"You mean the warranty timer? Set to go off 13 months from purchase :-) "

That could be alot closer to the truth than most people realize. When you buy the components in very large quantities and they are all exactly the same it makes it almost possible to get it down to a couple of months, semi-reliably. In fact that brings up a topic I am going to start in SED about just that. I'm glad this took that direction which remonded me of it. Collegues in the repair field don't see it but I have pretty good evidence that there is a planned failure of software due to ESR in a certain filter.......

However I do not believe that is the case here. I believe it was luck of the draw actually, even if the actual fault turns out to be the same in each unit. the OP did not specify if they were the exact same model.

Even if the humidity got to ridiculous levels I am still going with luck of the draw because in an LED backlit set there is only a couple hundred volts across each string. In a CCFL backlit set, of a certain model I could go with environmental factors. IIRC there were some Emerson (et alii) models that had problems with part(s) of the backlight array shorting out, which made the inverters look bad. The design was such that you could not disconnect each lamp separately so it wasn't hard to get a bit tripped up. Gawd i am sick of brownwares but after my recent experience with that Tektronix....LOL
