Annoying whining noise from screen - where do I stand?

Hi folks,
I thought I'd get some opinions from folks here regarding the screen whine issue that some LCD screens get.
I recently bought a replacement Tytn off ebay after breaking my screen on mine. When it arrived it looked fine. I put it on charge and started cleaning it. That night I find out it's got a high pitched whine making it almost unusable.
I've sent it back to the seller and asked for a refund but he says he's contacted HTC to find out if it's a recognised fault or not. If it's not something that HTC acknowledge then he's going to make me make arrangements to pick it up from him.
Does anyone know if this is a recognised fault with the phone?

AFAIK, I have got some experience with some other handheld, it appear the pitch noise come from LCD inverter. seen some picth noise in early production of O2 Atom, old handera handheld. even nokia e61 generates pitch noise if you listen it closely. what I can not confirm is where the LCD inverter located, in mainboard or in LCD modul it self. So I can ot tell you which one is broken.
Well, it's just my opinion.

Thanks for the input tianz.
I've found loads of info on Google about it. It appears to be quite common with some of the older mobile phones.
Is it reasonable to expect me to have to accept a phone which has an audible whining noise to it?

Well... actually it's up to you, If you find the whining noise is too loud for your ear maybe you should return it while you can. As my experience when I had Handera with whining noise, I had return it. but when the replacement came back, the whining noise get worse and the company said that there's no problem at all with my Handera.
Later on I found out what cause the whining noise, and actually very simple to fix it, just find the inverter ?? (sorry I don't know what they call it in english, It's ferit core and copper wire wrapped around it) and put some wax from the candle or you can use glue.
And again, I don't know where exactly the inverter located in Hermes device, or maybe they use different model of inverter in Hermes.
So, It's up to you. I hope my answer will satisfied you. Thank you

Unfortunately I bought the phone off ebay and the guy isn't keen to refund me - although he currently has both phone and my money.
He says it's not that loud/irritating so I'm not sure what to do.

I've just dealt with it. The whine is only there when the LCD screen is on. My 8525 phone is exactly 1 year old. It can be irritating though, so I use the earbuds whenever I can.

Unfortunately for me the guy that's selling me the phone doesn't appear to agree that it's annoying:
=========================================================
"I have tried the phone and whilst it is just possible to hear a noise if I put my ear to the screen (why ayone would need to do that I have no idea) there is no audible noise when the phone is held to the ear as used in a normal phone call"
=========================================================
I can hear it loud and clear even at arms length - the phone doesn't even need to be near my head!

That's the problem, he doesn't want to refund. He wants me to keep the phone so he doesn't have to deal with it.

if you do have the phone in your hand, please confirm the pitch noise come from the front speaker or LCD it self. I'll try to help you finding the inverter located. I'll look around if I had a chance to open my 8525 again. Thank you

i am on my second tytn. I bought both used and in PRISTINE condition on Craigslist. The first one I bought had it, and so I asked for my refund from the seller. The second one (that I have now) just started the whining noise yesterday. I've had it since January 2008. It SUCKS!!!

PS: the noise is heard when I put my ear to the front speaker up close. It's weird. I heard it as soon as I move my ear to it. However, after about 5 seconds I don't hear it anymore. Then as soon as I move my ear away, I hear it again... It's like my ears become desensitized to it? lol

It is quite possible. It's like being in a room with an analog clock. You may have sat in that room 100 times, with the same noise around you, but for some reason this time you can hear the tick tick tick of the hand movement. Then just as quickly as you noticed it you can suddenly not hear it no matter how hard you try.
It can be a state of mind that results in your heightened sense of hearing or it can be as simple as your tympanic membrane being a little tighter.

Like the above poster said, I hear mine sometimes too, and other times I dont hear it at all.
To the OP, if the seller has your phone and your money, then either keep asking for your money back and if that doesnt work, email ebay or give him bad marks stating what he has done. If that doesnt work, you can threaten to take him to small claims court ( Judge Judy ). What is loud and irritating to you maybe not to him. Get you rmoney back. Hope this helps..

I think the reason the sound goes in and out is due to the fact that the screen istelf goes to sleep after a few seconds, or what ever you have set in the system...
My screen starting making this noise a few weeks ago. I love the functionality of this phone, but I am pretty much done with it. I can't stand all the tweeks that come with it.
I jumping to the iPhone as soon as they make the slinbox player for it... and they roll out the 3g functionality.
Don't mean to rant, but I am just frustrated.

I think the phone was dropped of damaged and that is why it gives off a high pitch sound.. Mine dropped onto a hard concrete floor. It looks and works perfectly fine but immediately after it emits a high pitched sound when ever the screen is on.
This is not normal for the TyTn which means it was damaged in some way prior to you getting it. Demand a refund.

Hi guys - the person I bought the phone from is still waiting for HTC to get back to him so he still has both the money and the phone.
Even if HTC say it's not a recognised fault, it's still unusable to me because it's really loud to me.
I'm not sure there's much I can do as I'm not exactly in a strong position to make demands.
Personally I think it would be unreasonable for him not to refund me but then he might not be a reasonable person.

The sound is definitely from the LCD - the speaker is fine once the screen is switched off (i.e. you can turn the screen off while on the phone and it's still fine).

I've had 3 8525's, one of them had this problem from day one. There have been a few threads about it as well.
I have just learned to turn my screen off during a call. It's real easy and quick, besides, you aren't looking at the phone when you are talking on it, and if you are, you probably can't hear the whine.
However, if you don't want to deal with the whine, then don't. Hopefully you paid through paypal and can just file a claim if the guy doesn't want to be fair. It is a defect and they should back you up.
If not, look to ebay and see if there is anything further you can do with them.
Call HTC yourself. Don't wait for him.
good luck

yes mine also does it i have just learnt to put up with it, but yes like drakkahn said you should ring HTC yourself and see what they have to say

[MOD] Speaker hole enlargement

Hey all, watching some flash videos today made me notice how poorly the N1 puts sound out the back speaker, even compared to my old G1. I remember back in my Blackberry days that people used to mod the backs to "let more sound get out", and so I started looking into this...
First off, the speaker is GINORMOUS in relation to the slit. If you look inside the back where the speaker is, you can see a little internal grille, and the small slit for sound to escape. There's also a TON more room where that grille isnt attached to the back (same shape as the slit, only about 5x the size) that could be milled out pretty easily, and still retain the "keep crap out of the back" feature of the grille.
So, this leaves me with a few questions:
Where can I get a replacement back, in case my mill catches a bit more than I anticipate?
Anyone else interested? I figure if I set up to do one, I might as well bang a few others out instead of setting up multiple times.
Once I get a second back, I will be going at this with pics and hopefully notable improvement in projecting sound into my hand, and back toward my face!
I might not be a software hacker, but when it comes to this sort of thing, I figure its the best way I can give back to the community!

Give HTC support a call and tell them your cover doesn't line up properly(I don't think any of them do) they'll send you out a replacement. If they don't they can sell you one for ten bucks I think.
Hope to hear good results from your mod, might do it myself.

I actually think the small slit does something to amplify the sound..
Take the back off, play music, put it on. Notice it gets louder when you place it back on..
I don't know though, but I'll be following this thread!

Yea, I think the OP should test and see if there's even a noticeable difference without the back cover. I would think not...

Try removing the cover, sounds WAY worse.

Yes, I completely realize the back sounds bad off, its acting as a resonator, or isolating front from back waves of the speaker, which causes phase cancellation. Thus why im not removing the cover, just making the one hole bigger. It SHOULD not lose the "low end" that it has with the back on (if you want to call it that.
Either way, Im hacking at least one up, Ill post results!

Do it. (poor phone!)

I would suggest to replace the speaker with a Desire one, some people who have both phones pretend it's way louder on Desire, and yes it's the same form factor and size so it should fit

It is quite a bit louder without the cover but sounds bad due to the lack of resonance.
Shouldnt be too bad with just an enlargement, make sure you put something to block out dust. Let us know how it goes.

I've found that attaching one of these to the back quite useful...

or try a vuvuzela

I think the engineer who designed that whole was well aware of resonance qualities. If you make that whole and turns out better, you should apply to HTC job hehe...

@Hummeroid
Good idea ...
What about drilling mini-holes arround the "slit" ?
Instead of making ONE BIG hole ...

Very Interesting mod idea...I think the small drilled holes would be an effective test.

Or just cup your left hand around the back of the phone.

I looking for the out come of this.

Nah, everyone does it.. I mostly do it when I want to listen to something quiet, I can turn it down and redirect the sound towards me.

I actually have a really good pair of earphones. I prefer that the main speaker is in the back, instead of in the earpiece like some phones. Prevents earspeaker blowout and call quality is damn good with this phone so far.

I try to put it up against a wall. Your hand can work to absorb sound waves, thus deadening sound and lowering overall quality; but drywall bounces the sound waves back nearly impeccably. Desks, etc, any hard surface should do the trick.

Phone mic oversensitivity [FIXED]

I take no credit for this, I remember seeing it in a thread here (which I can't find now). Been plagued with alot of background noise always coming thru the mic whenever I call from anything less than a silent environment. Someone here suggested a small piece of tape placed over the mic hole on the inside of the back cover with a small pin hole poked thru effectively attenuating the amount of sound coming thru to the mic. It works! Took it one step further though cuz I always seem to get alot of resonance from the cover itself so I cut a 1×1 piece of duct tape & put it on the inside of the cover in the area opposite the battery. Its just enough to dampen the resonance & improved call quality to everyone so far. All this after setting everything to evrc-b too.

I'm so glad I'm not the only one having this problem. I've been fighting with Verizon over this issue since I bought the phone. They think I'm crazy and wouldn't give me a replacement of a different brand. They've replaced the phone 3 times now even though I told them it isn't defective, and it's more of a design flaw of the phone.

I will be giving this a try. During many of my calls people say where are you at, just be cause it is crazy loud on there side. The only plus side, my wife never calls to talk to me anymore during the day.

Worth Sending in for Issues?

Issues I am seeing is while phone is on speaker phone and on the desk on its back people can't hardly hear me. Also, I have a tendency of putting the phone on my shoulder and people are complaining of "static". What I found out by calling myself on my another phone is the "static" noise isn't static but a rubbing noise. Almost as if there is a hidden microphone back there and I am rubbing it while I talk. I can't hear it on my phone but when I call my phone from another and rub the back of the phone you can def hear it.. Sounds like rubbing your finger over a microphone. I called huawei and they said I could try x, y and z and nothing worked so they suggested I send my phone in... The problem with that is I need my phone and I haven't a back up. Is this something others have noticed?

The microphone on the back of the device isn't hidden, it's right under the visor. The problem with the rubbing noise isn't due to a manufacturing defect, it seems more due to how you use the device, so I doubt that will be treated as a warranty issue by Huawei. As for people not being able to hear you while on loudspeaker, I don't have that problem so that very well may be a genuine issue with your device. It's a shame you didn't buy directly from Google, they send you a replacement and then have you send the faulty unit back, so you're not without a phone.

Thanks for the reply. The not buying directly from google was a huge mistake on my part (i was speaking to my wife about it night before). The rubbing noise is actually coming right about where the nexus letters are on the back. I can rub my finger across while talking and produce the effect. Which only proves that putting it on my shoulder would yield the same results. In my opinion it shouldn't be that way.

I see, no I don't think it should be that way either. I'd be getting it replaced, pain in the butt but it might be your only choice if it's a big problem, which it seems like it is.

Top/Left speaker extremely quiet

I've recently noticed that my left/top speaker is incredibly more quiet than the bottom/right one. It's almost as if it's stuck in "phone call" mode.
I'm rooted, still on Marshmallow (last available version). I've tried rebooting in safe mode, nothing changed. I've tried disabling all Xposed modules, nothing changed.
The speaker is not dead. It simply plays extremely quiet when compared to the other one. Could it be broken or is there something still left to try via software?

I have the exact same issue. Unfortunetly restoring stock Google image didn't help either. I think it's the hardware

same, but mine is bottom/right speaker. it will come on intermittently, usually if i flip phone around a bit into landscape....
am on 7.0 stock/rooted...battery issue has become an annoyance to...ugh

I had this happen after a drop of oil (skin treament oil, not motor oil) must have landed on the grill. At least that is what I hypotheseized. Problem was, because it was an oil, it wouldn't dry any time soon. It was actually so quite, when I made my first call the next day, I thought my phone wasn't working, then I heard a very, very, very faint noise from it. Compressed air in a can helped clean some of it out, and it got better- tolerable. Over the next few months it's very slowly improved, but it's still a little muffled sounding compared to the right, but the volumes almost match now. The grill in that speakers still gathers more junk than the bottom one, and I have to keep it cleaned out regularly. So, any chance a contaminant of any kind got in there? Try canned air, or gently use a clothing pin to remove any dirt/debris.
I think it's a poor design, because my Moto X Pure never had any issues with speakers getting wet or dirty.
Edit, I'll add that the entire speaker was muffled, not just one part of it, the whole thing sounded like it was broken, and I thought it was a hardware issue at first. Until the canned air got a little tiny bit of liquid/oil out. It improved by 50% with the canned air, then over months it slowly evaporated.

Check for metal shavings in the grill as well. I work in a factory and get it all the time.

Hello... Don't know if you're running stock kernel, but you could try to change the gain of the top speaker with a kernel manager app: Kernel Adiutor, EX Kernel Manager, etc... If your kernel supports it. Most custom kernels do.
Good luck...

I could do this but I fear that to get acceptable results I would run the speakers entirely out of specifications limits.
If opening it was easier I would have checked for oil/water/anything inside.
It's supposedly still covered by its warranty but that would lead to an undefinable period of time with no phone... and that's unacceptable for me.

Hey. Sorry, I didn't think about the "out of specs thing". The warranty won't cover water damage anyway. Though a repair seems to be the only way to get it to work.
I fear myself the day I'll have to open mine...
Goos luck...

Success! Re-reading everything that was written here I tried remembering if something happened that could justify what I was experiencing. And I remembered a cocktail spilling on the phone. Back then I didn't give it much thought because the phone kept on working and I wiped away everything almost immediately. I tried blowing hard inside the speaker grill and blowing and blowing, I noticed some liquid coming out of the speaker, very little drops obviously. Then I "slapped" the phone against my thigh repeatedly.
Thanks to everybody chiming in and especially @HikingMoose that made me think about this.
And now volume appears normal from both sides of the speakers. Using GoneMad Music Player I can adjust speaker balance and both seem to be playing at equal volume.

I have the solution for that
I'm pretty sure I have the solution. That's not b cause I'm claiming smart lol but thats because exactly what has happened to my nexus 6p recently. I got this nexus 6p as a replacement so it was new. A month later the top speaker got extremely low. If you go to YouTube and type stereo speaker test. You would here the difference. I thoughts it's the Oreo update/hard reset/ google support but no luck.
Anyways I thought of taking of the speaker grill to see if any dirt is blocking it. Believe it or not: as soon as I took the top speaker off I noticed the speaker got back to work asbestos loud as the bottom one. So it's the grill mate.
JUST BE CAREFUL THOUGH, it's hard to put the speaker back in. You might not be able too unless you glue it or something. I could not find anywhere to buy a replacement. Just be careful
