fried my computer video card with TV??

shocked277

I pluged my computer video out to the video in or 15 pin vga marked (pc) and the tv fried the board on my computer and when I un pluged the computer I guess I touched the pins on the video cord still attached to the tv and it shocked me to. This was good enough to melt some of the pins on the cable and gave me a good shock too. Can any one tell me what is going on with this tv. In a nut shell the tv has voltage on the vga input, its crazy. Thanks for all your help Brian

Is the TV properly grounded?

I checked the grouding and the polarity and voltage all checks out.

You should have both the computer and TV off when you plug or unplug the video cable. It isn't like a USB connection that can be plugged in with the power on. Have you checked the computer? You may have done more damage than just the video card.

I have done this with 3 other tvs in the house and have not ever had a problem. I still dont see why a vga input would have high voltage coming out of it for any reason. enough voltage to shock some one and melt the pins on the conector with sparks ..... something does not sound right. I plug in the vga connector with tv on all the time.... never an issue....

I tend to agree that it should be no big deal "most of the time" to connect equipment while it is turned on.
The biggest "normal" potential culprit might be static discharge which has the potential to cause some damage.

I also agree that this sounds more serious . . . like somehow 110V has gotten to the TV's vga port . . . I'd certainly check it out, or have it checked out . . . and until then absolutely not try to connect anything else to that TV.

You've likely been lucky. It doesn't take high voltage to fry a video card, or an entire mainboard, for that matter. Everything I have read regarding computer connections, with the exception of USB, cautions against making or breaking a connection while the computer is on.
