[1000mp] Protecting Front Ends/lost front end twice

[J. Agius]

I bought a Mark V in 2001 and it lasted until 2004 when it died.  The
front panel showed all 9 or S's or some such things.  I sent it in for
repair to Yaesu and it cost me $500+ to have the control unit replaced.
They said it was bad but could not find out what caused it.

Two days ago I turned it on again and had the same problem.  I have
faithfully disconnected the antenna and the 110 plug when I am not
using it, however, the ground wire is connected. Don't think it can be
a lightning problem. The rig works fine when it works.

Has anyone experienced such problems so frequently.  I am thinking of
giving up my allegiance to Yaesu.  I have about $4000 invested in this
rig since I bought it.  Now, of course, they are cheaper.

Is it worth fixing again??
