The only thing you can do is to first of all try blowing some warm air into the open cassette holder for about 30 seconds, as if its simply condensation on the sensor that will cure it, however you "might" have to leave it for about an hour to allow the memory to reset so do not immediately think that you have failed. By the way warm air like from a hairdryer on its lowest heat position. If however this doesnt cure it then the undermentioned is the only course to take for a satisfactory outcome. ----------------------------------------------------------------------- Please note that anyone requesting this info must "NOT" choose to hide their e-mail address as the info is complex with attachments and has to go to a "DIRECT" e-mail address which cannot be done if its hidden. It should be pointed out that the info is really in two stages the first being the dew sensor cleaning procedure, however should this procedure fail then the only option left is the second and more complex task of disabling the dew sensor circuit. Although anyone thinking on this is advised to observe the undermentioned. -------------------------------------------------------------------------------- - AN IMPORTANT POINT CONCERNING THE MODIFICATION - The instructions given are really aimed at technically minded people of a "practical" nature who are acquaint at working on smaller electro-mechanical devices of a precision nature or who have a flair for this sort of thing, and so in the interests of not making the situation any worse I would strongly advise anyone who does not really consider themselves to come into that category NOT to attempt this work, as it involves separating the case and the unscrewing the main circuit board to gain access to the board below it, this requiring the disconnection of ribbon cables etc, it is also necessary to carry out the precision soldering of two "very" narrowly spaced PCB pins so the possession of a fine tipped soldering iron is also absolutely essential! Taking the above into consideration the qualification mentioned is really a MUST!! It should be emphasised that there are "NO" shortcuts into permanently getting over this problem other than what's been aforementioned, as if the "no dismantling" dew sensor cleaning procedure doesn't help but the "partial dismantling" memory reset "does", even this can only really be adopted as a stop gap measure as the CPU could lock up again at some point in time and indeed in many cases does exactly that!
