I have had my top 2004 programmer going on a year now and I have to say i have been very dissappointed with it. It has never worked reliably for me. I have searched this forum for a solution and others have had the same "trouble pin contact..." problem as myself. The mods always say clean the contacts. This is complete BS as i have had maybe a dozen chips on this in its year of use. What I have found so far is that when it has worked the USB power test comes back with a lever 3 weakly power. It tests with a lever 10 OK when it has all its problems and refuses to work. Before you say its my computer i have tried many different USB ports between several different computers all with the same results and very unreliable operation... this leaves me to believe it is a bad driver or software issue.. can anyone confirm my findings?
well thinking the problem has been with insufficient power from the usb I cut a usb cable in half and connected the power to a pda 5v/2a power supply. programmer detected fine in topwinen but same problem was every chip inserted has "trouble pin contact" and usb power test returns a 10. all of this was on a new laptop with a fresh install of topwinen ver 2.33
I can no longer say I would recommend a TOP 2004 programmer or any TOP branded programmer. My unit no longer works and of course it fails outside its 1 year from purchase date so its just a useless pile now.
I got it to work one more time yesterday.. between reloading the drivers and testing voltages on the circuit board it programmed a flash chip.. then that was it.. trouble pin contact afterwards for everything. I don't understand this thing.. obviously it isn't broke but it just wont work about 95 percent of the time I try
I have the same problem, pin connect error. I have 10 power every time and clean contacts. I check everything, even try the chip in every possible zif setup. chip programs every where else so not a bad chip. just no pin contact on crapy top2004 programmer. If anybody finds a solution, please let me know.
