X200 AFFS Buzzing issue
X200 AFFS Buzzing issue
I've installed the AFFS screen HV121WX4-120 works but now there is a strange buzzing noise coming from behind the screen. I was wondering if this is normal or if I missed a step? Also the white colors are more yellowish so not sure if thats a symptom of the problem as well or just needs to be calibrated.
Re: X200 AFFS Buzzing issue
AFFS screens can be yellowish and your buzzing noise may be the inverter.

Re: X200 AFFS Buzzing issue
The yellowish hue may be a sign of an aging CCFL.
The buzzing noise would be the inverter, which could be an issue with it or the CCFL.

Re: X200 AFFS Buzzing issue
Hm there was no buzzing sound before I swapped the display.
Edit: weird after maxing out the brightness the noise went away. It seems the noise culprit is some sort of transformer or maybe the inverter shawross mentioned? Copper wrapped thing where the the power adapter from the display goes.

The inverter does have a transformer. And yes it's the source of the buzzing sound.Lundy wrote: ↑Thu Oct 25, 2018 8:11 amHm there was no buzzing sound before I swapped the display.

It would be nice if there exists a LED backlight kit for this screen.

Do you think I should try putting some hot glue on the transformer?axur-delmeria wrote: ↑Thu Oct 25, 2018 11:57 amThe inverter does have a transformer. And yes it's the source of the buzzing sound.Lundy wrote: ↑Thu Oct 25, 2018 8:11 amHm there was no buzzing sound before I swapped the display.

I don't recommend putting hot glue on something that gets warm. Maybe some clear 5-minute epoxy?Lundy wrote: ↑Thu Oct 25, 2018 12:49 pmDo you think I should try putting some hot glue on the transformer?axur-delmeria wrote: ↑Thu Oct 25, 2018 11:57 am

The efficiency of two screens equally sized with equal numbers if pixels are equal. The time spent by a 4:3 user complaining about 16:9 is proportional to the inefficiency working with a 16:9 display, therefore the amount of useful work extracted is equal.

I have to turn my shed into a proper workshop first. Still lacking key pieces of equipment and furniture, but at least I got a soldering station now.Thinkpad4by3 wrote: ↑Fri Oct 26, 2018 8:43 amMake one.

Besides, I don't even know how xiphmont makes those LED strips, or where to source the LEDs-- maybe I could scavenge them from broken laptop screens or flatbed scanners.
I'm hoping to finish setting it up by year's end. Among the things I need is a ladder chair.

There's a simpler design that uses plywood and doesn't need any fancy woodworking skills (like making mortise and tenon joints).
Oh, wait, we're derailing another thread again.

Re: X200 AFFS Buzzing issue
And there is no cushion so you should modify the mechanical to add that.

Re: X200 AFFS Buzzing issue
Hey thanks for help I ended up fixing it for the most part by removing a orangish wrapper around the inverter and wrapping it with electrical tape. Noise is still there but suppressed enough that I can't hear it unless my ear is up against the monitor.
btw if anyone has a color profile they can share for this display would be great! I've seen it shared on some older threads but the download link seems expired

Re: X200 AFFS Buzzing issue
If I were you, I'd replace that inverter before it sets a possible fire to your laptop!
Those transformers put out between 700 and 1200 Volts, that's why they start buzzing as they get hotter with age.
