Having problems with your Digital Cameras ?

I have several TRV 20's. I seem to be "burning out" DV ports on them. I'll have a project whereby I take a Power Point Presentation on my gateway computer, and utilize an on board scan converter program (PPT 100) sold by DataVideo Corporation which converts Power Point to video. It may work once or twice, and then suddenly, the computer no longer recognized my TRV 20. Nor does my stand alone editor (ScreenPlay by Applied Magic Corporation) recognize it either. Both did at first.

Hi Mark,

effectively it looks like your computer is blowing firewire ports.

To start , whenever you connecct firewire you must ensure that both devices are off, or you risk to blow the firewire. If you swapped the cable with computer on , that may have been the cause. Firewire has unregulate 30V, and blowing it is very easy.

To ensure firewire on camera has blown, remove batteries from camera to discharge firewire capacitor and connect again to a device either that the computer with the problem.
If the computer firewire port has a short on pin 8 (+30V), or a bad contact on pin 5 or pin 9 (shield), then it can be easily blow connected devices' port. If you connect firewire cable while device is on, and touch computer pin 8 with cable pin 6 (gnd) when sliding connector in, there you fry camera firewire immediately.

If the problem on computer persist , a wise choice would be using the computer with an external firewire adapter like the one here.

Hi

\015\012Thanks for using FixYa. The port on your gateway computer is faulty and has damaged the connectivety IC on your trv's. This has happened due to overvoltage or wrong polarity coming through the gateway computer port. Please don't use that port again, and get this port replaced. Using the port on your gateway computer can cause other devices to either not function properly and can even cause them not to function at all.

\015\012Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
