Hi there,
I'm repairing a CTX S760A LCD monitor, replaced all the caps in the switching regulator section as they were bulging. That got the monitor going for more than a second :-)
Now the LCD works fine, apart from an odd shimmering pixel effect in top right hand corner after the thing warms up for a few minutes.
A photo of these shimmering pixels is at:
I've not seen this effect or fault before.

Monitor okay when cold, pixels start shimmering in top-right corner after some minutes. Show up on black background, display is normal on bright background but pixels show on single colour background.
Anyone seen this? What fix?
The service manual is available on the 'net, but the one I found is only module level, no circuit diagrams.
Thanks, Grant.
