          It is for a Svod4 I ordered it over 2 month ago. They kept saying it will be posted at end of the week this went on till I asked for a refund .It did turn up and after i plugged it in and did not work. When I contacted them they did some tests and told me to open it up.When I did it had a melted ic the one in picture. I replaced it and still not working. Contacted then and now they just ignoring my messages. Asked for a replacement and they told me it's my fault. All I did was plug in the usb port and install the drivers. I have other programmers so I know how they work. Now left out of pocket so got to try to fix it. They are just ripping people off I would avoid if I knew that before. I am in the process of reading the MCU to get the info from it to reprogram a new one if I need to replace that also.

            Read access will most likely be 100% blocked for the MCU; there will be protection against reading the firmware (security against cloning...).

              I seriously doubt that you will be able to read the MCU because a lot of them are locked from being downloaded unless you have what call a token or something similar to that

                Yeah mainly do electronics on cars ie MCU reading from vw clocks ecu's etc. As I am auto electrician have access to lots of programmers. We have to crack the mcu so we can gain access to the clocks. Sure it's no different.

                    DVR HIKVISION DS-7208HWI-E1/A BOARD DS-80104 REV 2.2 help identify burnt components
                    by thesame
                    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 .

                    How can I identify varistor which have been blew up?
                    by chth96
                    I mistakely pluged 100v japanese retro game console to 220v outlet.
                    So It seems that glass fuse and varistor have been blew up.
                    I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
                    Is there any way to identify varistor type in my sega saturn PSU?
                    Any reply would be appreciated.


                    EDIT:
                    It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...
