Re: Medion P16042 (MD 30671) TV from 2014, Samsung panel (?), problems on one side on
The cables on the two sides of the TCON board are quite delicate, they don't have a proper connector and are just soldered (?) to the board so I'm a bit scared to meddle with them. Of course there could be a bad connection on the other end of the cables going to the panel (I don't know yet if they are accessible at all) - I would have to disassemble the whole thing some more.
But wouldn't the picture be more "stripey" if the problem would be with the flat...

Medion P16042 (MD 30671) TV from 2014, Samsung panel (?), problems on one side only
[B]TV[/B]: Medion P16042 (MD 30671) - sold in Austria 06/2014 (German [URL="https://www.medion.com/at/service/_lightbox/handbuch_details.php?did=13544"]end user manual[/URL])

Re: AOC E2460 PDA with PSU: 715g5361 - Monitor turns black
Hello!
After some months have passed a quick update:
The monitor started to turn off after a while again, so I exchanged the last capacitor ([B]C809 - 33μF 100V[/B]) as well:
But after replacing it and turning the monitor back on, there were horrible color aberration (see first image).
After a while I discovered that the culprit was the [B]flatflex cable[/B] connected to the panel - when I pressed it down manually, the color was fine again.

Thanks for all your valuable input!

Interesting, since the store is actually one of germany's bigger electronic stores (Reichelt, [URL="https://secure.reichelt.de/Elkos-radial-85-C/RAD-33-100/3/index.html?ACTION=3;ARTICLE=15125;SEARCH=rad%2033%20100"]link to the article page[/URL]; the picture shows a Samsung cap, the datasheet is for Yageo - I guess they sell "whatever" for general purpose caps).

Re: AOC E2460 PDA with PSU: 715g5361 - Monitor turns black
Sorry for the long time since my last post.
I desoldered all capacitors for both the logic board and the power board and measured their values:
[B]Logic board 715G5270M[/B]
[CODE]CAP MEASURED* SHOULD BE
C430 101.4μF 0.67Ω 2.1% 100μF 16V
C702 104.3μF 0.64Ω 2% 100μF 16V
C705 100.6μF 0.7Ω 2.6% 100μF 16V[/CODE]
Note: MEASURED format: [I]Capacity InternalResistance VoltageLoss[/I]

Re: AOC E2460 PDA with PSU: 715g5361 - Monitor turns black
After de-soldering the three caps from the logic board (a PITA as always...), I measured them out nof circuit now:
C705: ESR=0.67 Ohm, Vloss=2.1%, Cap:101.4uF
C702: ESR=0.64Ohm Vloss=2% 104.3uF
C430: ESR=0.7Ohm Vloss=2.6% 100.6uF
(again, all three are rated 100uF, 16V 105°C)
Measurements are to be taken with a grain of salt, since I didn't use professional equipment, just a LCR-T4 component tester.
However, I think these caps are not to blame?Leave a comment:

Okay, I took out the logic board and spotted 3 electrolytic caps, all of them "JH" branded and without any visual defects.
All three are rated 100uF, 16V 105°C, as stated in the [URL="http://www.go-gddq.com/upload/2012-04/12040910493283.pdf"]service manual[/URL]

AOC E2460 PDA with PSU: 715g5361 - Monitor turns black
I have a [B]AOC E2460PDA[/B] LED-backlight Monitor (built 2012) which is giving me troubles. I am not an EE, however am competent enough to solder an replace caps (as I did with my trusty HANNS.G HG281d). Any pointers would be appreciated!

Re: New Members - please post your introductions here
Hi! I had a dying Hanns.G HG281D monitor and managed to save it by replacing the caps. After that I swore to myself that I'll never throw away anything without having checked the capacitors, so naturally this forum is a very useful resource.Leave a comment:
