Sony DCR TRV 345E bug without error message.

Hello, I recently bought a second-hand Sony TRV 345e. The cassette compartment was blocked with a cassette inside. I managed to eject it because the tape transport roller had shifted horizontally and was blocking everything. In the end, the camcorder worked well for two days. And then the problems began. I tried to connect the camcorder to an AVerMedia H727 card via S-Video and a BMD Intensity Shuttle, both using S-Video. In both cases, I had no image on the PC, even after hours of struggling to figure out why. With the AVerMedia card, I had to disable the resize bar in the BIOS to install it. It displays "no signal," but it blinks. By touching the S-Video cable a bit or toggling with the RCA, I get a spike of sound for a split second.

But anyway, the most worrying part is that a few hours later, sometimes when I was playing a tape, the camcorder's screen suddenly went black with some artifacts, and then the camcorder shut off. This only happened at certain times. So after that, to turn the camcorder back on was a hassle. I either had to wait or disconnect and reconnect the power charger or even the battery, then it would turn back on but would glitch again after a few minutes. But it only happened when my S-Video cable was connected to the camcorder's port.

Then after that, it got a bit worse. Now, when I manage to turn on the camcorder, I press play, and the camcorder stops immediately. And similarly, I have to wait a while before I can turn it back on. But each time, I get no error message. I even tried only using the battery, without the charger, and it can happen too. And now even without the S-Video cable connected to the port, it can still happen.

If anyone has any idea where this might be coming from... thanks!

I could make a video of the problem later.
