Greetings guys, I am burning up the 4LCD-A cards at an alarming rate, and cannot locate the cause. This card is equipt with an +80v dc-dc power supply, when I meter the circuit at the MDF I am seeing 90 to 98 volts, its turning on my MWL when there is no voicemail for that line. I have isolated the card so that nothing is connect other than the PIM itself, I put in a new card and still 99v so I removed it right away, as to not smoke another card. Any help would be appreciated. I just replaced the main power supply to eleminate that as a problem.
