LCD Screen Noise

[cphuelva]

Hi all,

I bought a Vaio FS315S on December, and immediatly I noticed that when setting brightness less than a full, the lcd panel made an annoying noise.

I opened a case with Sony, it was sent to Service (apparently repaired), but when returned the noise was still there. Might be "normal"? I've tested with others Vaios (not exactly the same I own) and there is no noise...

Note: One month ago I found two or three threats about it in this forum, but by now they have disappeared!

Thanks a lot!

sounds like the inverter

no LCD screen should not make any noise.
CRT may make but not LCD

May be other component? It seems to come from the LCD... it's a constant noise...

Thanks!

Hi cphuelva,

I get a slight hum if I reduce the brightness of my screen. I'm guessing now but if you use a dimmer to dim lights in a house sometimes the dimmer switch makes a hum, so maybe it's down to a resister or transistor like device.

A quick look on google and I have found mention of this from owners of different Vaio models, so yes I guess it may be 'normal'

So... in other words, this might be normal... What I can't understand is why other vaio notebooks don't have the same noise...

Anyway, I'll use it with full brigthness!

Thanks a lot!

Hi. I no this isn't going to be much help. But I have the FS315E and I have no problem with the screen it at any brightness.
I never makes any kind of noise.

Hi

I purchased a fs315b noticed the same noise when i dim the brightness. I contacted sony & they recommended it should be sent in to be checked over problem is they lost it in the process. Got a fs315s for replacement this week & as you know makes a noise when i dim the brightness. I'll contact sony again now & ask em t check one of their own laptops & i'll let you know what they say..
