    I want a Portugese Guitar

    There may be some water left inside the phone. Blow it out with a hair dryer and then bury it (and the batery) in dry uncooked rice for a few hours to absorbe the moisture, or if you have a few silica gel packs (dessicant "Do Not Eat!" things used in packaging and bottles of pills) put the phone and battery in a plastic bag with the silica gel packs for a while. Either way it will hep dry the inside places water can get into that you can't see.

        i had forget to mention on first post , when i dry the phone i gave hot air at 50 degrees for a while to dry most possible if there was a bit of water inside , lets hope now the silica idea works mate.

        btw i request big time :P but yes portuguese guitars are good and nice sound

            I've played a Filipino variation called a laud (pronounced loud). It's like a small 12 string guitar but the laud is smaller than a Portugese Guitar, like a big mandolin strung like a 12 str guitar.

                Yes. It is a bit harder to play but not much. If you are used to a 12 str guitar it's played the same, just smaller.

                      Help with trying to fix phone that is not charging (Pics inside)
                      by SluggerB
                      I have two TCL A30 phones.

                      Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

                      New Phone: Works fine, bought as a donor board to try and repair Old Phone

                      My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

                      by sam_sam_sam
                      I got lucky that when I got home and was about to get some ice out of the ice dispenser I hear and see water running down the outside of the ice dispenser what the heck is going on here

                      At first I thought that the ice dispenser mold was cracked so I brought a new ice maker because this one has been in there for about 10 years now

                      Well I put the new one in and wait and I wait for the water valve to open and let water in no such luck well there is a way to check the function of the motor and the water valve on this ice maker just need a jumper wire “L” to...

                      new OS on a Sonim XP5s phone
                      by keeney123
                      To you programmers out there I want to know if it is possible to put a new OS on the Sonim XP5s phone? I only need this phone to make calls, receive calls, have a list of contacts and be able to call voice mail.
                      I bought this phone new Sep.2021 as an unlock phone from a third-party seller. The phone worked fine until Jan 2022. I then had intermittent problems with the sound setting resetting itself. One of the settings, outdoor, would go to silent all by itself. When in silent mode it does not indicate a call has come in. I missed very important phone calls. All the other setting in sound...

                      Stagg sms12p audio amp has water damage
                      by edugimeno
                      Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
                      I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
                      There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
                      There is only one signal wire connecting the first boards...
