Re: LCD32A558 lcd panel failing
Maybe AUO panels are good now compared to before, but this one seems just to be the heat which unglued the tabs. This is why I wanted to try the thermal gap pad solution. However the ones that seemed situabl for this were the Digikey ones which are not sold in Europe.
Do you know of others that can be used that fit this purpose? The ones posted on this thread seem to be slimmer and might not cover the entire frame while disipating heat.

Re: LCD32A558 lcd panel failing
Hi
Tanks for your reply. It's a Samsung model LE32A558P3F
I agree it might no the best solution but it's clearly that this line will bring new friends soon with it as it has happened on the previous panel. Since I have no options for a reflow or resoldering this seemed like a decent solution for some time. Even if it's 2 or 3 more years.
ThanksLeave a comment:

Re: LCD32A558 lcd panel failing
Hi, I tried to find there but didn't find any similar one to the one I posted.
On here I found these but none of them seems "fat" to stick it in. Any suggestion?

Re: LCD32A558 lcd panel failing
Hi, thanks for the answers.
As far as I know it's not an issue with the caps but I checked them (don't have the tools) but I looked at them and there are no bulged capacitors or whatsoever.
Yes. I saw that link, it's the same one I found in another page. The problem is that I am from Europe and the shipping costs are nuts to just send that to Spain.
So I wonder if there's another way to get them? Another brand maybe that has a distributor in Europe?
If not maybe anyone willing to send it to me through the cheapest...Leave a comment:

Re: LCD32A558 lcd panel failing
Well apparently are the ribbon tabs in this case. Would the capacitors affect on this? If I pres the ribbon tab it comes and goes. I would think it's a heating issue that causes the glue to go away?Leave a comment:

LCD32A558 lcd panel failing
Hello
I have had this TV for a long time. The first panel it had started to show vertical lines on the left side of the screen related to the ribbon tabs, althoht the panel started failing after.
We replaced the panel for a used one and after 2 years it's starting to exhibit the same behavior. It's only a thin red line that shows on the left side of the screen, same location
Right now it's only a thin line that disappears after a few seconds. But eventually the line won't disappear and it will bring new friends to the party.
I assume... -
Re: LE32A558 vertical bars and line
Hello
I know this is old, but I took so long on dissasembling it due to an illness that has been following me for years. I am better now, althought not well enough. So I apologize to everyone trying to help me
I dissasembled it again yesterday (it's still open) and correct, the leftmost ribbon tab is defective. But there's another problem, the black vertical line won't ever dissapear.
I uploaded a video where you can see the line and me tuching the tabs.
I also tried to disconnect both...Leave a comment:

Re: LE32A558 vertical bars and line
A few more questions.
According to the video, the latex tube method seems to work best. Foam or thermal don't work that well?
In case there were more than one or two tabs failing. Is it possible to apply this method to all of them in case it's needed? I assume that over time, some other tabs will fail as well
And another question about security. Power supplies or inverter can still hold a charge even if the TV is unplugged. How can I discharge it? Shorting the power plug cable pins when it's unplugged from the wall?...Last edited by albertocastillo2001; 02-01-2014, 12:52 PM.Leave a comment:

Haha, ok, thanks
I asked because I have tried to use duck tape on electronics and it always became loose so maybe I didn't pick the right ones or not good brands..Leave a comment:

Re: LE32A558 vertical bars and line
Hello
Sorry to revive this topic. I took a lot at my TV for the problem, but couldn't access the T-CON tab, because it's under a metal shield with 4 scres, I tried to remove them but it won't come out.
I was able to check the LCD ribbon tabs. Apparently those are the failure of the TV. I didn't check them with the TV turned on because I am not an expert and I am quite afraid of getting electrocuted if I accidentally touch the power supply or the inverter board.
I checked the video one year ago and that...Leave a comment:

Re: LE32A558 vertical bars and line
That's interesting.
Is that connected from the T-CON card to the panel?
However is a bit risky to test it for me while the TV is on (shock risk) These TVs get high voltages as far as I know
Do you suggest me to attempt this anyway or take a look at other things as well? What else could be failing looking at the symptoms?
Thanks!Last edited by albertocastillo2001; 03-20-2013, 12:14 PM.Leave a comment:

LE32A558 vertical bars and line
Hello
I own a Samsung LE32A558 TV for a bit more than 3 years (warranty expired after 2 years) and since then I've been getting these strange vertical lines on the left side of the TV, their size is around the difference of a 16:9 and 4:3 image on the left side.
Most of the time that vertical rectangle turns into different colors, like based on the background of the rest of image.
Here you can see 2 photos: [url]http://www.mediafire.com/?9glba6k50t4iw[/url]
One of them is the thin green vertical line
The other one are the vertical bars, they are...
