Thanks for repply...i did all it takes to erase the chip but nothing seems to work...i spoke with some people where i work...and they said they a kind of "special programmer" that can erase almost all chips with any configuration ...i will try that but after the holidays...thanks again all for...
yes..i also have ZiF programmer board with its 3 zif sockets ....i tried there also to program this chip..but nothing...i think that i will gave up...
i have a pic16f684.... i will begin to study it and learn on it...maybe it;s better
I understand...i am a begineer and i am trying to learn...i indeed use a breadboard...but what i cannot explain myself is why i can program another chip....same model..with the same hardware..but not this one...it's for sure something with the program i wrote in it but even if i knew what i...

2.programmer is a pickit2 clone..but i can reprogram another part without problems...prog from sureeectronics.com
3. i tried in a dedicated circuit...i tried in circuit... a way or another if i put another part it has no probl seeing it...no matter the circuit...
4 the code is working on...
I tried everything....Use Vpp first and all that..but it still broken...i dnon't know what to do...since i wrote that program it isn't recognized by the programmer...but the program executes on it...
If anyone else has an ideea please reply..i will post also the program wich i last written in it...

Hy guys,
I'm new to this forum and to picmicro also..and i believe i made a mistake and now i don't know how to solve it.. I programmed a pic16f628a with configuration word like below:
__CONFIG _PWRTE_ON & _WDT_OFF & _INTRC_OSC_NOCLKOUT & _BODEN_ON & _LVP_OFF & _CP_OFF & _MCLRE_OFF
And now...
