2405 High Pitched Squeal

DOMIN8,

Actually I am in Round Rock, Texas. Just outside of Austin. I have asked Product Group for a run down on the 2405 squeal.

I have exactly the same issue with brand new 3007 (30" LCD). When the LCD is in max brightness, it squeals. When the brightness is anything than maximum, then it buzzes. I've gone through two replacements already, and they are all buzzers. Guess nothing was learnt.

Let's see if this makes sense.

A ceiling fan that buzzes, you can correct it by installing a variable resister or what is commonly called a light dimmer switch in the wall, between the ceiling fan and the current supplied. Turn down or dim the light a little and buzzing is gone. In this case too much voltage causes motor to buzz. This is more common in ceiling fans than you would think.

In the case of the monitor 3007, "When the LCD is in max brightness, it squeals. When the brightness is anything than maximum, then it buzzes", it seems poorly regulated power is causing the buzz and sequel sounds. Could be a faulty variable resister, because that's what controls the brightness variation in the brightness control. Whether it’s in a chip or a separate resister, that’s what I would look at first. It could also be a power supply issue alone.

Only skilled electricians or EE's should try to fix this issue, in this case it would be Dell’s Engineers.
Owners and users should take caution and not risk injury or electrocution.

Someone else stated it's like a buzz a faulty florescent light starter makes. Maybe there is a light starter issue here. ???

Thought that might shed some light on the subject. No pun intended.

Good Day.:)

Why does not Dell help me ? They must surely be aware of this "High Pitched Squeal"

I can think of the following scenarios:


1: Dell have no quiet 2405FPW monitors to send me. (Likely)

2: Dell have no quiet newer monitors at all to send me. (This would be really bad)

3: Dell don´t allow me to return them for a refund -otherwise thats a simple solution. (Likely)

4: Dell are trying to "wait me out" - maybe I give up and don´t bother them any more. (Likely)

wincc ,
Keep exchanging at Dell's shipping costs to and from you as they have not corrected the issue yet after two attempts.

Don't let them off the hook, Dell needs to correct the issue at hand.

all the facts:

Dell don´t send me any new monitors because the case has "escalated", I´m not allowed to speak with a manager(the refuse to give me a phone number to anyone,and they don´t call me back)I have tried with email but the answer is that I have to wait for an answer....
There is not much to do, I have bought my last private DELL and at work (where I´m in a position to buy and/or make recommendations there is no more DELL stuff either).
As you understand I´m extremly dissatisfied.

I actually got my replacement monitors very quick and very few questions was asked so they should have credit for that, but when I kindly asked for the next replacement to be two silent monitors it suddenly became problems.

I know that this forum is not the right way to communicate with DELL but I have no other option.

"because the case has "escalated", To what level? The fact you want Dell to honor the warranty is not an escalaton in itself.

If it's defective and your warranty is valid,
let's see if ChrisM can settle this issue amicably with you.

Your warranty that came with your purchase and is part of the package, as well as deciding factor to purchase the model you did, is a binding contrct with Dell in most parts of the world.
I don't think Dell would want to violate that warranty, would they.


Post any feedback form Dell.
Let's see what happens.

Yes, you would have to start a process and get everything in writing. If that's not good enough, then a letter from an attorney should rectify the situation and an amicable solution should follow immediately. Just my opinion, and it works 99% of the time.

Update:

A new email to DELL with my company address,phone# and email did some difference... this time a manager called me and said that they is sending me two NEW monitors and although he could not promise that they were quiet either in the end I should get two quiet ones. Now I have to wait and see ,maybe I get two new 2407WFP´s (btw. are they quiet ??)

If they are 2407 A03's, they are quiet. Mine are, anyway :)

"Yes, you would have to start a process and get everything in writing."
Yes, starting any kind of paper trail usually gets positive responses form reputable companies.

I try to do business casually and sometimes you just have to step it up a notch.

Post back on what you received and let us know if the issues are resolved.

Update:

Two new 2407 A03 just arrived, no more high pitch squeal instead I got a humming sound.... but setting the brightness to 100% made them silent, I think I have to live with that. ;)
