Warren, the flashing LED can be an indication that your monitor is having power issues. Recheck your connections, if all of them are okay, disassemble your monitor and check the caps on the power board. Use [http://www.ifixit.com/Device/Dell_E193FPc|these guides] to work on your monitor. It does sound like you are having a few failed capacitors. Hope this helps, good luck.
