Re: TC Electronic Studio Konnekt 48 revival
I am leaving here the schematics in case somebody needs them. Link is down for some weeks already.
Mr Khron was right. The easy fix did not last.

Re: TC Electronic Studio Konnekt 48 revival
I had some issues with my Konnekt Live, after I plugged it in with the FW cable reversed. In my case the FW connection was good but the DAW indicator in the control panel was grayed out randomly. I narrowed down the issue to the FW chip. What I did was to "cook: its pins with a bit of solder, hot air station and some flux. I have had issues before with other machines where a reversed voltage caused a weak solder point to break but not the device itself. I guess I was lucky! Worked wonders! Thanks to Khron and everybody else!

Re: Samsung SyncMaster 2493HM black screen with power
Sorry for hijacking your thread. But since my problem was "Samsung SyncMaster 2493HM black screen with power" it looked ok to be here since other users that may have a "Samsung SyncMaster 2493HM black screen with power" would find it here. Even you could benefit from that.
Best. Glad your mon is working.

Re: Samsung SyncMaster 2493HM black screen with power
Now the ON/OFF rail that should be more than 2.4VDC is 2.8VDC. Also the value in the A-DIM rail increased to 1.3VDC. Seems healthy huh? I think I was right into assuming that these fuses do open over time, in a slow fashion. Obviously one would think it would be better to replace it with one of the same kind, that I would do eventually.
Some funky stuff appeared on the screen, that I do not know where it came. If someone has an idea, please share. See the attached pic:...

Re: Samsung SyncMaster 2493HM black screen with power
Hm also found this 3A pico fuse its putting 117ohm.
The specs from LittelFuse are here:

From the description:
"The NANO2 Slo-Blo® fuse has enhanced inrush withstand
characteristics over the NANO2 Fast-Acting fuse. The
unique time delay feature of this fuse design helps solve
the problem of nuisance “opening” by accommodating
inrush currents that normally cause a fast-acting...

Re: Samsung SyncMaster 2493HM black screen with power
It seems like a lot of samsung boards use the same specs. I saw the picture of this one and is pretty much the same as mine. Here are some mfg specs:
1 24 V
2 24 V
3 24 V
4 24 V
5 24 V
6 GND
7 GND
8 GND
9 GND
10 GND
11 No Connection (DO NOT CONNECT) *ERROR DETECTION (NORMAL : GND / ABNORMAL : 5V)
12 Backlight On /Off [ON:2.4 – 5.25 V, OFF: 0 - 0.8 V]
13 Dimming Control [0V:Min, 3.3V:Max]
14 No Connection (DO NOT CONNECT)...

Re: Samsung SyncMaster 2493HM black screen with power
Thanks for chiming in. Well, maybe I did not elaborate enough. The cap that I replaced from the power supply has been working fine since like 7 months, the monitor had problems to turn on its power led, and the cap was leaking. The inductor transformer broken solder making the arc; I fixed it like 9 months ago. Now yesterday it did not start all of a sudden, but its power led remained lit, so I am not suspecting of the PSU, also because of it putting the right amount of volts right in those rails.
Now talking about the...

Re: Samsung SyncMaster 2493HM black screen with power
Hi. I am having blank screen problem with the same monitor. Had to replace a power supply cap recently, and now no screen. Also, I had an arc sound with a flickering from back light. Had to resolder one of those inductor things in the inverter board. If you turned the olights off you could even see the arc. Whats happening with the quality control from samsung?
I tested the voltage in the on/off line, my cheapo non exact multimeter read 0.28 volts on that line. The 24v rails all of them have power. The first and...
