Question about Sharp XL-MP130 CD Shelf System
The problem is with the "power on" relay (RL841) located on the power supply board. Unplug the unit and take off the side panel and top cover. Remove the screws to remove the CD changer. There is a small black rectangular relay just below where the AC cord is soldered onto the PC board. Carefully remove (actually break it off carefully and gently & throw away) the plastic top housing of the relay. Plug in the unit and with a pencil or stick, manually actuate the coil armature while pressing the power on button on the front of the unit. I can almost assure you your unit will return to normal operation. Put it all back together and you're done. The blinking red 4 times followed by a long pulse indicates a power failure. The start up capacitor had drained and couldn't provide enough voltage to pull the relay coil in all the way.
