    Video Converter from Composite to Vga V2V Pro2 not working

    Hi everyone I have a problem with this converter, I have no video output on the vga, I have already changed the small chip highlighted on the photo because it heated a lot and I thought it was that, now it does not heat anymore but equally I have no signal, I noticed that the two diodes right on the vga connector are shorted could they be those?

    Which pins of the vga connector do the diodes connect? they could be tvs or zener diodes used for protection.

              If you look at the photo I have indicated you with which pins the diodes are connected

                Didn't you let me know anything?

                  I have an update, the diodes removed from the circuit are good, on the circuit they give me the short

                    Piece of advice: each time you see a square IC in a brown socket like in your second picture (top left) put the card on a table and firmly press down on the IC (you will hear a snap), or remove the IC and reseat it. Time and heat make these type of IC’s in sockets like that wiggle out. I’ve fixed a lot of no POST issues on older computers, just by pressing down on that IC. I am not saying it is the cure for all, but that is the first thing I would do.

                        I tried to hit that chip but nothing works, it's hard to pull out and I wouldn't want to do any damage

                          stick a small screwdriver in the corners of the holder and lift the IC a little, then press it very firmly all the way back in the socket.

                            What Zener Diodes on a Linear Power Supply
                            by caspian
                            Dear members,

                            I have a linear variable power supply with unknown brand name that I used for voltage injection.
                            Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
                            In addition, I discovered that its zener diodes are defective.
                            I can replace the burned transistors.
                            But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
                            Therefore, I cannot replace the zener diodes.
                            I do not want to test the zener diodes in a test circuit to discover their model or value.
                            no schematics are available...

                            Hello
                            I have a problem with this video converter, I only have S-video output but nothing composite, I think the problem was caused by the sometimes high voltage that is found in the composite rca connectors when there is an amplifier signal and I happened to feel this tension also on my body by touching the plug...

                            This is from my son’s gaming computer that at first had minor overheating issues when playing a very intense game with it causing the computer to crash or reboot

                            Then bough a new motherboard and a new computer case that a cooling system in it already installed also brought the cooling system for this video card but now the issue with it is that it randomly rebooted screen goes blank randomly and suddenly video freezing or started with video being there then blank screen and then the video comes back or it just stays blank for a while and then maybe it will come back but it...
