I am having an issue with my visual display and was wondering if anybody else has had this problem. When I turn on the machine, I don't get a visual read out on the display. The machine is working fine because of the tones it is making on known objects. This does not happen all the time and it is hit and miss. I can turn it on ten times and seven of those times I get no reading. I would say that it is just glitch and have a Whites Tech check it out but this is the second machine I have had this trouble with. I purchased my first machine in October of 2005 and within a month the machine developed the same problem. I sent it back to Whites and they sent me a new machine. I have used this machine for about a year (100 hours on it) and now the new machine has developed the same problem. I have changed the batteries and the machine has never been abused or damaged. Am I just unlucky or is this something that others have dealt with on the MXT?
