OK, I read the last 55 pages of fixes for U99. I have seen the same question asked , but never really answered to the point where I can understand. (may be the Panasonic help desk senerio is catching on) The unit was reset as the clock is flashing 12:00am on startup, wheather a soft of hard boot, the unit displays TEST *L1 then goes to U99 and hangs. I cannot even get the unit up long enough to load the new firmware. What, in simple 1 to 10 steps, fixes the TEST *L1.
