Syntor x 9000 froze to death Help!!

[n4dxx]

Got my syntor x9k programmed for 2 meter and used it about a month and the other nite it got down to about 28 degrees and the next day when i tried to turn the volume up the buttons would not respond the only button on the control head the works it the repeater button,still transmits and receives fine..I kinda figure moisture has gotten in it somewhere any help here would be appreciated..Thanks

Bring the head into the house. you will need both a T15 and a T10 Torx driver to work on the head. On the back is 2 T15 screws that hold the 2 sections of the clam cover together. Take the screws out. Sort of pry the sections apart from the screw side. Then press a little toward the other side and the covers will separate. They have a few slots on the other side that keeps the covers together.

A note here is that the circuitry is static sensitive. So take caution when working inside.

The front half that contains the front panel has the circuit board held to the plastic cover with 4 to 6 screws. You will need the T10 driver to remove these screws. Again a word of caution here. do not over tighten these screws when replacing them. I generally rotate the screws backwards when replacing them to find the threads. The screw will fall slightly when you find the threads. When this happens, you can then turn them clockwise to tighten them down on the board.

Anyway, once all the screws are removed, you can separate the circuit board from the front cover. You will see a rubber type material with the button dimples on it. If the head has been in service for any length of time, it will probably have all sorts of crud on the membrane. If it came from police service or a public works vehicle, it probably has coffee remains on it and the front buttons will need to be unstuck from the sugar tar.

i have always been gentle and lifted the membrane up and used some alcohol and something like a Q-tip. Put some alcohol on the Q-tip and gently clean the underside of the membrane. Do the same with the circuit board. If there is a bunch of brown crap on the top button side of the membrane, I use a damp toothbrush to remove it.

The buttons can be cleaned with warm water and the toothbrush. you will have to very gently take a small pointed object and pry off the clear plastic molded part that holds all the buttons in. I normally start with the large end and work one corner up. The do the other corner. You should now be able to use your hand and work the other horseshoe ends up. Be careful here as you don't want to break this plastic piece. it is what holds all the buttons in place.

Make a list of what buttons go where. Once you flip the front cover over, they should all fall out. There will be a small rectangular button that is the dim button that goes in the upper right corner just under the Motorola name. Unless you know it's there, you will probably not even notice it.

Clean off the buttons with a little effort of the toothbrush and some water. The brown coffee and sugar mixture will come off. Do the same with the front cover. Don't scratch the smoked plastic lens that covers the display area. The all the pieces dry before trying to assemble it all back together. It will help if the rubber membrane is kept open so both the circuit board and the carbon blocks in the membrane can dry. Yo will notice that there are some small round extrusions on the membrane that need to line up with some small holes in the circuit board when you lay it back down.

Can't count how many of these heads I have cleaned up and put back into service.
