I bought a junky LT a while back, and made it in to a great looking machine with some help from a friend that re-capped and cleaned the board with a pressured micro washer..  anyways I retro-brighted it and it looks and plays great.
  
  My only problem is the AC adapter input.  I have the OEM AC Adapter, but it sits loosely so that when I'm playing and I move a little bit, the game loses connectivity for a split second and restarts.  I'm wondering if anyone has any experience with this problem. 
  It sounds like it's simply bad soldering on the DC input, but that isn't the case.. I was wondering if anyone has tried and 3rd part AC adapters that sit a little more snug?  Also has anyone tried any battery mods?  I'm thinking of making a rechargeable battery supply that connects to the back SCART pins.  Thanks
