What A Load Of Trash !

This video is an example of trash talk.
Bad Caps Will Not Cause Lines Out On Any Display FFS !

Re: What A Load Of Trash !

lol why would changing capacitors to a higher voltage solve anything if they are not under rated?

There is no way that 35v cap is getting anything over 35v

Re: What A Load Of Trash !

Ikr its just a load of rubbish lol and the caps he said to change are part of the audio circuit on that board lol how would that cause issues on the screen

Re: What A Load Of Trash !

There were no video of the before and after. Just a dude talking about some problem and what you should do to "fix" the problem. He guarantee 90% of the TV with the issue will be fixed. I guess most will fall in the other 10%

Actually he said 99%.

Well, I did have one LCD monitor display garbage on the screen, likely due to high ripple from bad caps in the PSU (the caps did look good, though). After trying many other things first, I finally recapped just the 5V output (used only by the logic and t-con boards). That fixed it right away. No more issues. Been using that monitor on and off for a year now too.

That said, I am definitely not defending the guy in the video. He seems like another clueless "electronics technician" with a camera, just like many others.

Re: What A Load Of Trash !

Yeah haha, bad caps can cause interference in the Lvds line but that will affect the whole screen I meant lines/rows of pixels out or multicolored.

Re: What A Load Of Trash !

Yeah don't you know? Bad caps in a computer monitor can cause all sorts of problems like happy faces and weird flashing ASCII characters showing up on the screen! Kind of like the post on a computer after the ram check when the old stoned virus came out lol how many of you are old enough to remember that?

Ohh can they thanks for the info will look out for them symptoms lol haha

I have seen random line glitches, not fixed, caused by a noisy regulator. It's not unreasonable to suggest that bad capacitors could cause that fault. Fixed lines are almost always the panel, especially if there's a limited number of them.

I have also seen this on a Cmo panel where a bad regulator caused lots of red lines across the screen and no display. But bad caps I highly doubt will cause this the guy in the video was just talking nonsense tbh

Re: What A Load Of Trash !

I tried super big caps to fix th lines but, it didn't work.
I found that yellow electrical tape worked better.


I'm not sure why but, It's still hard to see the picture.

Re: What A Load Of Trash !

You're doing it wrong, you need to use a blowtorch to reactivate parts of the panel. Failing that take the TV to your local DIY shop and ask them to cut a glass pane to match the size of the screen. Replace the screen with that and the picture will be perfect, although always white, but few people are concerned about this.

Exactly...

Manufacturers aren't stupid. Samsung didn't install 10V caps on a 13V rail.

Capacitor lifetime isn't strongly affected by applied voltage. Even up to 20% above the rating only increases leakage current and decreases life slightly, which is hardly noticeable for most electrolytic capacitors. Ceramic caps can be over-rated 200-300% on voltage and generally function fine, although capacitance falls off significantly with voltage this does return when the voltage is normal.

Re: What A Load Of Trash !

As you can see I still get part of the picture I guess I shouldn't complain.

That's a hell of a nice sony! How much do you want for it?

Re: What A Load Of Trash !

Here's an interesting bit of (True) garbage for ya!

In the 1920's/30's, when electronics really was in its infancy, Capacitors of the electrolytic type were sometimes used as Voltage Regulators....

Often electrolytic caps were fluid filled things like cylindrical lead-acid batteries, with different chemicals and metals used....

Also, overvoltage and a fairly high current would cause them to internally spark and knock....

We have come a LONG way!

I wonder if we'll get some bozo on youtube saying to check for knocking caps!

Re: What A Load Of Trash !

Guess my engine in my bmw m5 is a 1930s capacitor. Huh. Lol

I work on vintage electronics and I have seen you capacitors before and yes they are an interesting breed

If its always white your new glass probably has an as15 chip fault
