It’s 100% out of the ordinary. I’ve used and successfully recalibrated several trinitron monitors, including another CR1 chassis and I’ve never had this problem. I never make any judgements until the monitor has properly warmed up, and I’ve done the white balance procedure in WinDAS several...

Well yes, but the brightness is creeping up at the same time. When G2 drifts on a trinitron and gets excessive, it’s usually also tints the colours. Maybe those 2 things are just happening discreetly, but you can see why I made the comparison? Either way, it was just an observation. What I’m...

It may well have nothing to do with G2. But in my original post I explained the symptoms I’m seeing are the same as what happens with the expected G2 drift on Trinitrons, but vastly accelerated. That is the biases only, drift in a non uniform way, upwards. I WBP this monitor just a few months...

I’ve recently come across a very old post where someone detailed replacing a resistor (R941) on the main board of a CR1 chassis monitor to fix the G2 drift. I wonder if that’s my issue and the resistor is just so cooked it’s allowing the brightness to drift much faster than it usually would.

Thanks, on inspection they all look okay but I haven’t properly tested them. I think I’ve ruled out just about everything else though. I imagine it will be components on the A or neck board?

Sorry for the FW900 adjacent post. My FW900 is being repaired so I’ve turned my attentions to my F520. I’m having an issue which I’m totally lost with. The individual RGB biases constantly drift. They will literally be different each time I power the set on and let it warmup for at least an...
