Help - Remove TV out settings from TP

Hi Guys,
I have a very unique problem. Couple of days back while charging my phone near a lot of dew waters was found in my TP. It happened due to heater being on and the windows getting a lot condensed dew and hence water was found in my TP.
Even though i have used a hair dry to it an the phone seems to be working now, there seems a problem with the htc usb jack. Whenever i plug in the cable my phone works normally however once the cable is removed it goes into tv out mode and making my phone speaker to be not working. I have tried disabling the tv out settings in the registry however still whenever i remove the cable it shows me that tv out settings.
Could someone please inform me how to remove the tv out settings completely from the phone including control panel as i never it use it so that my phone can start working again. I dont have this problem when using the Eclair android however the battery life there is not good at the moment.
TIA.
self bump hope some one can help me.
HELP!!!
i have this problem as well. TV-out is taking over my phone. it rotates and and doesnt go back unless i reset. if anyone can help us out ill be happy to donate!!!
I also have this problem from a faulty USB cable. (grounded I think)
If someone can help to remove TV/Video Out it would be awesome.
Try this in your registry:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\TVOUT]
"Flags"=dword:4
To remove the icon you need to find out which mycpl entry it uses.
Go to [HKEY_LOCAL_MACHINE\ControlPanel\MyCpl] and look at each number till you find the one that points to tvoutsetting.exe (it is 15 on my phone). Once you find it, go to [HKEY_LOCAL_MACHINE\ControlPanel\xx] (where xx is the number) and set "Hide"=dword:1
Can anyone help me remove TV Out and Video Out completely? ):

Hard Brick (possible hardware failure)

I was wondering if I've encountered a common failure mode with my Verizon Galaxy S3 and if there are any possible solutions.
A week before it bricked, the phone was acting rather odd, rebooting itself spontaneously and at random; I didn't really think much of it until the following week. Applications on the phone had been running VERY slow and would often crash or hang; in addition, the phone was rebooting itself several times an hour at this point.
The last reboot hung for a while at the "Samsung Galaxy S3" screen before going to the home screen. At this point I realize there may be something serious going on, so I attempt to SSH into it and retrieve important information off it. Unfortunately, it proved to be too late; login attempts failed with "Argument list too long". A few minutes after my ill-fated attempt to save data, the phone crashed in the app launcher and initiated a reboot again; only this time, the Samsung logo never came up. Since then, I have been unable to power it on, enter recovery, or otherwise get any life out of it.
It's long out of warranty so I'm basically wondering what my options are to revive it and possibly get important info off it. Reinserting the battery does not work and neither does plugging it in. All options to enter recovery or any other sort of mode fails; it essentially acts like there's no battery inside and does nothing. Is this a common failure state for S3 units and is there a known solution? Has anyone ever used JTAG to retrieve information off the storage inside?

Plug it into your computer, or a wall outlet with the battery out. See if it mounts as a strange drive or the led light flashes for a second.
Oh wow. Yes it does have the red light when I plug it into the wall outlet without battery. Haven't tried the PC as I'm leaving for work and my USB wire is in the car but I'll assume that will work when I try it.

At least it isn't completely fried, this method should work:

Make sure it has no other sign of life first.
If you were on 4.1 then make sure you don't use a 4.3 file and lock your phone. Might have to do some digging around to find them, but they are around here somewhere.

iphone 3gs - continous restart - help

Hi,
I have a iphone 3gs which i purchased from eBay long back and.. Long story short, now I have multiple problems :
1> The phone doesnt show/have the IMEI # and neither does any other details like firmware etc.
2> The phone randomly gets restarted continuously almost every 1min.
I tried replacing the battery thinking the issue with restart would be with the battery but still it doesnt stop. Due to this issue I am unable to install the IOS software as it gets restart frequently and the installation stops in the middle. I am now thinking it might be problem with the 30pin charger cable (viz., not genuine) that i am using but not sure. Can anyone help me on how to fix this issue of restart and to get back the IMEI# on the phone again. Any help or suggestion would be really great.

H959 won't switch on.

The title says it all.
The phone sometimes will boot but then it will freeze and crash to a black screen. Have tried using a hot air dryer, replacing the battery (worked for a while) and even attempting to reset (turned off before reset could start)
Can't reflash ROM. PC won't detect the phone.
Anyone with this or a similar problem? I need a fix ASAP. And no, replacing the battery again does not help.
EDIT: New update: the device keeps on reconnecting from PC when I was able to get it started for 5mins. Was trying to root from PC so as to disable the 4 big cores but the reconnecting rendered it unrootable.
H959 unrooted
Stock v20a
Out of warranty (no LG service centre options)

Please anyone help me ASAP in an Emergency | Mobile not switching on from morning

Hi,
My mobile which was working fine till last night. Today morning without no reason its not switching on.
Make and model : Lenovo A7700 (2016)
OS : Android 6
There is no issue with battery or display or any part, it's was just on the table whole day idle. No physical damages.
All of sudden it's not switching on. When connected to charge even the logo needs to come if battery Is drained but its acting like a brick. If the display is the problem then atleast while connecting to charge the vibration needs to come. So there is no problem with display or battery.
Tried all the possible ways to turn on, nothing helped. When connected to PC it says last device you tried to connect was malfunctioned.
What happened actually all of sudden in one night.
I have done nothing recently with my phone nothing absolutely. It was just on the table. Last night I charged my phone and after Charing completed unplugged and kept as it was.
Please anyone help me so many documents are there in the internal storage which atleast I need to transfer to another phone.
Please kindly anyone help me with this ASAP.
Thank you in advance.
P.S : My mobile is not rooted or side loaded with anything. It's just as it is from the start. As mentioned earlier nothing absolutely nothing I done with mobile. My mobile had scheduled switch on and off feature so it will switch off on night 1o clock and turns on morning 6 o clock that was enabled many years ago and till yesterday no problem. But it today it switched off at 1 o clock AM with full charge and when I tried to turn on manually it's is not working.
Please Help me anyone to atleast recover data from internal storage.
