Question about Samsung T509 Cellular Phone

Number pad buttons dead

A few months ago roughly half of the buttons became unresponsive.  It was intermittent, but now it's permanent.  I really like the phone and don't want to purchase another.  Any ideas are greatly appreciated.
Thanks!

    I've opened the phone to access the buttons. The button is still a physical detent, not an electrical connection. Half the buttons are unresponsive. I'm unable to get under the next layer, it's all glued together. I'm not convinced it's a dirty connection. Half the buttons stop working simultaneously, when it is intermittent it's always the same group of buttons that either work or don't.

    the contact points are all clean and shiny. the non-working button contacts look exactly like the working ones.

    Thanks, I'm pretty sure the part has gone bad. Any ideas for a repair shop in the Oakland CA area?

    thanks again!

Open up the phone then use an eraser over the contact points for the keypad. Most of the time the problem is because moisture affects the contact points on the keypad.

Keypad contact, open the phone then clean the contacts using a regular pensil eraser, on the keypad, try to brush out the dust using a toothbrush or a small PC vacum cleaner

good luck

    thank you for clearing that out, it is just not a dirty keypad, the culprit will be the metal dome assembly, it is not easy to repair by hand, you have to have special tool for it, but it is replacable.



    refer to the link below for the part i mentioned.



    http://www.cellphone-repair-shop.com/GH5...



    it may be available in local cellphone part shops, plus you'll get free installation.

TV Rarely Starts


Check all the solder terminal at its main power regulator section circuit. Any loose solder terminal can poise this type of problem. Resolder all the suspected solder terminals by applying a little more solder. If you wish to get more details, check this site.

Remote's menu and input buttons, and television Input button not responding


well the problem sounds like it could be the IR sensor on the tv or somthing in that circut that is failing or the EPROM chip that controls : Vol up/down , Channel up/down , Power on/off ,Menu , Input selection , ect... is failing, thus this will trigger the protection circut to shut the tv down. this kind of a problem only gets worse and can dammage other components if not repaired soon so it will need testing to determine the exact cause

Tv is unresponsive


Does your set have a reset button on it? It sounds like we had the same problem from the beginning. In fact, we have bought and exchanged the tv 3 times because we thought maybe we just had a lemon. The picture would freeze and no buttons would fix it. We read in the owners manual about the reset button -- a tiny hole in the top of the power button on the right side of the tv. You can use the end of a paper clip and stick it in the hole to reset the tv. The tv powered off and then the remote and all the other buttons worked. Ours is still in the warranty but for the first month, it seemed like this happened at least 5 or 6 times. Haven't decided if we want to try to exchange it again or just live with it. Other than this, we love it!

Yeah,

Press all the buttons at the same time, threaten to through it in the toilet, then give it a couple of agressive taps.

It works.

Really.
