I didn't know if I missed an update on the firmware or not.

Plus, the board could not be operated outside the enclosure.

The new display is excellent. cheers, Johnny Siu VR2XMC   ________________________________ 寄件人﹕ Barry Cooper Thu, 04 Feb 2010 20:19:42 GMT Larry Phipps http://groups.yahoo.com/group/LP-100/message/1990 http://groups.yahoo.com/group/LP-100/message/1990 Yes, it is grounded. I have found since publishing the manual that sometimes it works better to have the tabs toward the PCB instead of pointing up. 73, Larry Thu, 04 Feb 2010 19:22:03 GMT Steve http://groups.yahoo.com/group/LP-100/message/1989 http://groups.yahoo.com/group/LP-100/message/1989 Thanks Barry - I guess I wasn't being ruthless enough! As you did, I just flattened the two ceramic caps to the board and twisted the regulator and I managed Thu, 04 Feb 2010 19:01:59 GMT Barry Cooper http://groups.yahoo.com/group/LP-100/message/1988 http://groups.yahoo.com/group/LP-100/message/1988 Steve, I found that by twising the regulator to an angle of 10 degrees or so to the edge of the main board it cleared the larger electrolytic cap. I bent the Thu, 04 Feb 2010 18:08:21 GMT Steve http://groups.yahoo.com/group/LP-100/message/1987 http://groups.yahoo.com/group/LP-100/message/1987 The upgrade kit arrived today and all was going well until I tried to install the new heat-sink on the 7805 regulator. After an hour of struggling, I still Fri, 22 Jan 2010 17:56:47 GMT Steve http://groups.yahoo.com/group/LP-100/message/1986 http://groups.yahoo.com/group/LP-100/message/1986 Thanks for all the advice folks. I think I'll probably go the LP100A upgrade route. Another line on the present display diappeared today, so it's obviously on Sun, 17 Jan 2010 17:29:36 GMT Larry Phipps http://groups.yahoo.com/group/LP-100/message/1985 http://groups.yahoo.com/group/LP-100/message/1985 Actually, there are a couple of other solutions, and they can be less expensive, but in terms of performance, quality and longevity, the GVFD upgrade is by far Sat, 16 Jan 2010 20:49:07 GMT Joe Subich, W4TV http://groups.yahoo.com/group/LP-100/message/1984 http://groups.yahoo.com/group/LP-100/message/1984 Steve, I recently suffered from the dead/dying display syndrome as well. I started with one missing line of dots, followed by a second then a third.

If it is so unfortunate that the display is dead, it Sat, 16 Jan 2010 13:17:22 GMT Larry Phipps http://groups.yahoo.com/group/LP-100/message/1982 http://groups.yahoo.com/group/LP-100/message/1982 I don't know if heat is an issue or not. My original LP-100 (serial #00000) is fine, and it sits in the basement where it gets pretty cold. I think it has more Sat, 16 Jan 2010 12:56:29 GMT Steve http://groups.yahoo.com/group/LP-100/message/1981 http://groups.yahoo.com/group/LP-100/message/1981 I switched on my LP-100 this morning to find that the top row of dots was missing from the display and the remaining "lit dots" were of variable intensity.
