Problem with LXI 934.53735190 camcorder

I obtained this camcorder, and the VCR works fine, altho it can use a new
belt and idler kit.

Here is the problem, when I put it in camera mode, there is no autofocus,
shutter movement, or any video from the camera. there are just noise lines
in the VF. the noise lines dissapear when I flip it in VCR mode.

I can hear a very faint off-pitch hiss in the camera section while in camera
mode.

Any Ideas? I have no schematic to trace anything down. sounds like the hiss
is comming from a DC-DC on the camera board.

I discovered where the hiss was comming from, it was infact a voltege
regulator module. the outputs are labled, and I decided to take readings.

Here are my results:

at 5V out I got 5V
at 9V out I got about 3V (hmm, makes ya wonder)
at 15V out I got about 5V
and at -8V out i got -2.5V

So, is this modual bad?? it looks like a micro SMPS modual. the hiss is
comming from the micro transformer(I thought so).

If i try to power it up without the module, no functions work except the
VCR. w/o the modual, the onscreen disp is gone, its just a flickering
raster. thats it.

If i plug it back in, the hiss comes back, the on-screen disp comes back,
and I get noise lines in the picture from the his, but no operations, no
autofocus, no pictrue from the CCD. the 5V must run the zoom, and the
on-screen disp driver. cause, they work. nothing else does. The VCR is fully
functional.

p.s. This modual is dedicated to the camera peice only.

If I flip it in the VCR mode, everything works fine including OSD.

In camera mode, all I have is a raster if the module is disconnected, if its
connected, I get his, but no power to the CCD, or varius motors, except the
zoom, the zoom motor functions. that must be derived from the 5V source.
Either that, or there is a bad IC on the other end that could drop the
volteges.

Any ideas at all??

I found out by looking up the datasheet to the chip of that micro board, it
in fact IS a SMPS. dedicated to the camera.

so, I jumped the 9V and the 15V together, cause the 9v has more energy than
the 15V, guess what: the shutter opened! and said low light, becasue there
still, isnt enough volts.

How do you fix those SMPS boards? due to the his that it has, I think it
involves a bad cap, or a bad xformer. this little critter isnt but an inch
by inch big. but it has full size caps and xistors on it. I think its a bad
cap, but im not sure.

if you have a normal size SMPS, what would cause it to hiss like it does?

Replace all of the caps in the DC-DC converter.

Hello Mike,

I have the same camcorder and I am having the same issue. Power on the camcorder and switch to cam mode and just noise lines no visible video. I took mine apart and was going to check the dc - dc converter per the below comments. Did you have any luck with yours?

I get the feeling Mike got rid of it 5-6 years ago.
