BZV49-C56 could be a replacement, check the datasheet and see if it matches, Pins 1 & 3 are likely connected together
The part is obsolete but I found a case style used on there lower voltage zeners that has pin1 NCAttached FilesLast edited by R_J; 06-14-2023, 09:37 AM.Comment

it's there for protection, find out why it blew up first.Comment

The guy plugged in AC instead of DC. The diodes did their job I guess.Comment

Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.
This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable... -
I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...

I noted that a number of consumer entertainment devices have the maximum speed marked on the wired network port and considering that there are broadband plans faster than 100 Mbit, the wired network port can be a bottleneck since some routers do not have Gigabit (only 100 Mbit) support for the WAN port let alone the wired network ports.
One other thing: Certain low cost network cables only have two pairs which limits speed to 100 Mbit. -
Hy guys , i have a DVR board DS-80104 REV 2.2 that was powered wrong, i have some smds on the board that are blown and i can't identify them , maybe if someone has this board somehow and we can identify the smds', i have searched online and i can't find a schematic.
The smds are SOT-23-6 , one of them i think it has the marking ADJF since i found another one on the board with this marking , but the other one it seems that it starts with AG or it looks like. I would really apreciate if someone could help me identify those IC's .
