How to fix h-hold on cctv monitor?

[[email protected]]

Hello all, thanks in advance to any help and/or advice that is offered
here. What I have is a Remmington 14764 CCTV unit that's H-hold is out
of whack. There is an adjustment knob for v-hold, but none for h. it
has 4 channels for video, and no matter what channel I put the camera
on (I only have 2 for testing purposes) and it happens on all channels.
The cameras also work fine on another display. I'm hoping to find ou
tif this can typically be identified to a single
resistor/capacitor/etc? Anywhere to start, as far as scematics for such
an obscure unit? Once again, thanks in advance.

Always post the manufacture name and model number for information about a
fault condition.

The monitor would have to be properly troubleshooted to determine the exact
failed parts. This would involve having the necessary skills, training,
service information, and tools to go through the effected circuitry and do
the proper diagnostics to find the faulty components.

Have you thought about contacting the manufacture of your monitor, to see
where you can take it in for proper service?

I'd start by locating the horizontal oscillator and changing the
electros in the immediate vicinity. Otherwise I'd download the
datasheets for the various chips and hope that the monitor's designer
has followed the application examples.
