Guest Juanjo81 Posted December 7, 2002 Report Share Posted December 7, 2002 Hi!I have finished my Midibox64 (with the old design, all in the same pcb), and when i turned it on, it don't work!!Before to solder pots and buttons my box worked, i think (the LCD write, etc)Now after solder pots and buttons anything goes well, thje LCD don.t print anything and the pots and buttons don.t do nothing.I have measured the voltage, and in Vdd i have 4.18VI now that the pic needs a Vdd between 4,8V-5,2V or similar, because i think that my problem is in my power supply.Why i don't have 5 volts like before solder pots and buttons? Is because my power supply gives less current that it must to give?Thanks!! Quote Link to comment Share on other sites More sharing options...

TK. Posted December 8, 2002 Report Share Posted December 8, 2002 Let's check it step by step: are you using a LCD with backlight? In this case you should disable the backlight first, this will lower the current consumption by 100-200 mA. Thereafter you should disconnect the pots - if the PIC boots again, you possibly didn't solder the pots correctly, so that they are causing a short circuit.
