Lee Smith Posted October 5, 2022 Share Posted October 5, 2022 I just replaced my front TV with a 50" flat screen Samsung. When I went to plug the TV into the lift controller box, I accidentally sparked the low voltage connector on the side of the controller. Here is a picture of the connector: Now my fold up/down electric lift is stuck down. I went to great lengths to remove the control board to find out who made it. Here is a picture: I found information on Tri Metal Fabrication, Inc but they are long out of business and the phone numbers and emails do not work. The former President was Mike McCormick in Eugene, Oregon.Does anyone have an electrical diagram for the Tri Metal Fabrication fold down lift? Or a parts source? I was able to verify that there is 110v power to the control board and the start capacitor tested good. Also, the various green control lights on the controller appear to be all lit. There are two limit switches. when pushed down, the switch on the right will cause a red light to come on at the controller and will test 28 volts at the connector. When pushed down, the one on the left does not turn a red light on but will test 28 volts at the connector, Here is a picture: Unless I can find a way to trouble shoot and fix, I am thinking I will straight wire and bypass the control board. I can fish an extension cord to the TV cabinet over the passenger seat for TV power. Of course, the motor could be bad. I should be able to straight wire the motor to test it without removing it. I can add a two-way momentary switch for up and down that works by reversing the polarity which changes the motor direction. I have tried to be clear but as you may have noted, this is all very new to me. Thanks in advance for any help you can give. Lee Smith Link to comment Share on other sites More sharing options...
