Hi Shamai,

1) Do the front buttons on the LVB Tracker control the rotor? 2) Check the wiring to the LCD display (one bad connection can easily cause this) 3) If it is not an LCD wiring problem, I would suggest programming another PIC chip.

Hi all,

After many months (Actually years) of good and flawless service, My LVB Tracker woke up one day with the display showing Z|||Z|||Z||| or sometime >|||>|||>|||>|||...

I tried several things: reset, checking the internal 5V supply voltage, etc..

I tried to reprogram the PIC using the PicProg program, but got only this reponse: "chip not recognized".

I followed the instructions in the document BuildingtheLVBTrackerv2.pdf (dated Dec 29, 2007) but no success

Any idea? anyone?

Pictures enclosed

73 & thanks,

Shamai 4Z1WS
