I have a Defender CT with its original PS and it's really tired. I really wanted to go the route of using a switcher to be more reliable, but most people here swear on rebuilding the original so I have tried that first and failed. Here are the symptoms prior to rebuild:
1. lighting on the CT lights, goes out after approx 5 min (this is bc the 2A SB fuse at location F5 burns up)
2. the game powers up but after about 20 min goes into a repeating rug pattern (mainly because the 1A SB fuse at location F4 burns up)
I bought the Bob Roberts rebuild kit which included all replacement caps, a replacement part for the heatsink (transistor?), and 2 replacement IC's and sockets for them. I swapped all of those parts out and the issues described at the points above persist.
I have reflowed all of the solder at the header pins. The +5 light also tends to go off unless I put my hand under the board in the midsection of the PS and push it up a little, then what ever connection is broken connects and the +5 light comes on. I can't find any broken traces or damage on the board in that area.
Please tell me what I need to do next. I love this damn CT until the fuses burn up.
