Question about LG VX-8700 Cellular Phone

Open Question

Im having problems with the speaker in my phone, It seems i have a bad contact between the lower part and the upper part of my phone for the speaker signal, I don't hear a sound. If I close the flap just a little bit to change the angle, i get the sound. If i put it on speakerphone, it helps, but sometimes, i dont hear anything there also. Is there anything I can do at home to correct the problem? I am an electronics technician, so i have probably everything i need to fix this, I just need some pointers. Thanks Francois G.

My sony ericsson has stopped playin my ringtones and is totally silent i have checked all my settins and everythin seems fine


When you go to set your ringtone, if it plays from there then it may be a problem with the settings still. If not, then you may have bad speakers or wiring. Best thing to do is check your warranty, if it is good then contact http://www.sonymobile.com/us/support/

It seems the speaker or buzzer is already busted and need replacement.sometimes it happens when the phone drop on the ground or been playing sounds fully loud for a long time.parts is available in any mobile service shop near you.

When im talking on the phone the other person can hear me but i cant hear them


then the speaker seems off. Did you drop the phone. Its most likely the contact are away from the speaker. Try to call using the headset supplied. If that works you need to bring the phone in for repair. If its out of waarenty you need to open it and restore the contacts to the speaker by gently prying the contact up a little and clean with some alcohol

If you never opened a phone before visit a phone shop.

good luck

Enough hot water for 1 bath. Replaced upper and lower elements and replaced both thermostats. could it be a sedament problem? heater is 5 years old. I never ran out of hot water before now.


You have 240Volt Marathon water heater.
These heaters have element burn-out problems.
http://www.thetankatwaterheaterrescue.com/forums/forum3/

Yes sediment can cause decreased amount of hot water when water cannot circulate around lower element, and sediment can cause lower element to burn out.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

Following list is overview of tank troubleshoot:

If you have some hot water, then that says several things:
-Upper element is working.
-Electricity from circuit breaker to upper thermostat is good.
-ECO reset button is not tripped.
-You do not have overheating event.
-Access doors and insulation are in place and thermostat not exposed to cool temperature that causes overheating.

That leaves following suspects:
1) Check if TP valve is stuck open, or pipe cracked, or faucet leaking and running hot water down a drain.

2) Upper or lower thermostat is bad.

3) Lower element is bad -and- maybe tank has built-up sediment

4) Loose wire. Open covers and inspect. Tighten screws very tight against copper wire.

5) Bad wire between upper and lower sections of tank.

6) Do complete 30 minute troubleshoot before replacing any parts.

I'd suspect the 6800uF caps, but I don't know for sure.

If it helps, here are the schematics for the upper and lower boards:

I wrote to KLH to ask for them, and explicitly asked for permission to post them here.

Hi,

Try adjusting the volume using the volume keys on the right side of the phone, try to lower it then make it higher if you are able to adjust it means there is no problem with the volume.try to have it checked in a repair shop cause in some cases the speakers migt have a defect or needs to be cleansed.
