Title: Repaired K7000 not working in original cab Post by: Entity on March 22, 2016, 01:31:16 am Hello, I have a K7000 chassis i recently got repaired by a reputable community member.
It needed a voltage regulator and a HV shutdown pot that was cracked, i also did a cap kit and flyback replacement on it prior to the repairs. I got it back, hooked all the connections in correctly, it was working 100% on the repairmans test rig, but it wont fire up in the original cab that i pulled it from. It did work prior to the repairs but had a squigly white line going down the middle of the screen, thus i sent it out for repairs cause i couldnt find the error in it. I put it in a life force cab that has a K4900 chassis in it normally, it fired up fine, i also put the K4900 chassis in the K7000 cab to make sure the monitor was still good, it fired up fine. All connections are in the same connections they were prior to being sent out, nothing has changed in the cab, the isolation transformer is being hooked up to the chassis and nothing else. The chassis is geting 125ish ACV, everything is as it should be inside the cab, yet the K7000 (originally hooked up to a 25 inch monitor) still wont fire up in its original cab. I have no idea what is causeing it to not fire up in its orignal cab, it worked better before i sent it out, minus the squigly line. Any thoughts, tips, tricks, things i should look into, anything would be much appreciated.

Make sure the chassis is Grounded. Make sure ALL the grounds are attached. There isn't much advice I can give other than get busy with your multimeter.
