Timer LED Does Not Stop Blinking
Causes: 1. (LED does not stop blinking after plug in) Disconnect the USB connector from the card reader to the front from the Chassis, if the LED stops blinking after 70 seconds replace the Card Reader part # 299P271010. 2. (LED does not stop blinking after plug in) Disconnecting the USB connector from the Card Reader did not help. Remove connector FC from the FMT PCB and plug the unit in, if the LED stops blinking after 70 seconds with FC removed suspect a problem on the FMT PCB (part # 930B924002), if the LED keeps blinking with connector FC removed suspect a problem on the DM PCB (part # 934C116002). 3. (LED does not stop blinking after plug in) On the DM PCB (part # 934C116002) check C81A2, C81A3, C81B3 and C81B4 (1000 UFD, 16V, 105C), if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C). 4. (LED does not stop blinking after plug in) On the FMT PCB (part # 930B924002) check C8F19, C8F21, C8F22, and C8F27 (16V 1000 UFD 105C) if any are bad, replace all of them with part # 181P734030 (680 uFD, 16V, 105C).
Note: The FMT and DM boards are no longer available through the mitsubishi parts dept. the entire chassis must be sent to Mitsubishi for repair, turn around time is 4 to 6 weeks. For more info. contact Mitsubishi direct.

I had the same thing and here is my fix. Take out your Formatter Pcb and note the service mount capacitors on the lower left corner by the ribbon connector. Should be a group of 18. I changed all of the 100uf by 16v, there are 7 or 8 of them. That and the other caps that you have changed fixed my problem. Have fun.
