Hello.

I have a problem with my DCR-TRV828E camcorder. For some time now when playing Video8/Hi8 tapes it can and it does at random point stop outputting video. Like it was unable to read anything off the tape, but when fastforwarding or rewinding with picture the actual footage is visible in ff and rew, but when the button is released and normal playback is resumed it looses the video again.

This happens both in SP and LP, I've tried cleaning tape, manual cleaning with isopropanol.

Might it be a problem with wornout heads, or something else entirely?

Do you still get audio or does that stop as well?
Does it fail with all tapes or only some tapes or some places on a tape?
Of only some tapes/places, is it the same place on the tape every time?

There were tapes where it would lose signal randomly, but after repeated playback it would finally play them. So that's one problem.

The second is that right now I have a tape, where it loses video in exactly the same moment, audio plays.

Is it possible that this might be because there is NTSC portion recorded on the otherwise PAL recorded tape? I've never experimented with NTSC, because I do not have a recording equipment to do so. I should probably finally hunt down NTSC D-VHS, DV and D8 equipment...

The camcorder can play back NTSC, but might not be able to output it through fireqire, only on analog, like VHS deck and only outputs via firewire linear audio converted to PCM and blanks the video, but on playback it reconstitutes whatever signal it can read and outputs it as PAL.

Another fun it is that a few frame portion of that recording pops up durnig the good segment on the beginning, just as if the tape was rerecorded.

The camcorder has no problems switching from V8 to Hi8 and D8 in the middle of the tape as well as SP and LP.

I will try to search if ay of people I know has an 8mm camcorder to try to play it there for crossreference.

The PAL versions of the newer Sony Hi8 and D8 camcorders can play NTSC tapes. On the analog output they output either NTSC 4.43 or PAL-60, depending on a menu setting when doing this. This does disable the TBC/DNR, I've passed it trhough Pioneer DVR-440 as a line-TBC when capturing NTSC tapes as these and related DVRs can handle these formats and output a normal NTSC signal. If it's a NTSC tape you should at least be able to see the playback on the LCD screen or the viewfinder.

Don't know how the react on the firewire out though. I actually have one of this exact model, but it's broken. The PAL Sony miniDV cam we got simply outputs standard NTSC format DV stream when playing DV tapes.

The image only being visible on fast forward/rewind could indicate an alignment issue, either with the tape or the camcorder. The 8mm camcorders seem to be particularly affected by this. If the recording camera had some loose tape guides that could cause alignment to change mid-tape, or between recordings. Granted, if the image goes the audio will typically be affected to, as the 8mm formats records audio together with the video tracks.

Checking it on another device first may be a good idea, though make sure you thoroughly test it before putting any important tape in to make sure it won't eat tapes.

Well, there is no image on te LCD.

So the only option might be to check the tapes on another machine, or try to get the one responsible for recordings.

What are the age and brand of the tapes? Symptoms are similar to the problems I was having with older Sony tapes.

The joys of capturing Hi-8 tapes! (Not! Sony tapes suck!)

Trying another player is a good idea.

That you get audio, even during the video blackouts indicates that the heads are working at some level. I am not familiar with your player, but it sounds like it has video "muting" where in if the image fails to meet certain criteria it blanks the screen. During scrubbing the blanking is disabled. That it changes location on many tapes would indicate that it is more than just a tape problem, although that could be a contributing factor.

I vaguely recall something like you describe happening a number of years ago with a player that had one of the two heads partly clogged.

I trust the machine is OK with D8 recordings.
