HI, i have a brand new GQ-3X, i have already burnt 20 EPROMS sucessfully (27c801 and 27c1001) but suddenly , without any particular reason, all the EPROMs programming i have tryed stops at 53%
I have tryed with 8 different EPROMS, restarted my computer, but it's always the same thing.
When it comes to 53% the VPP led goes low and then blink rapidely
(here is a video of the led :h**p://youtu.be/LHSNYryrGxQ)
Any idea to solve it ? do i need to change a damaged component (i have skill for it) or do i need to send it back to MCumall ?
Thnaks in advance for your answer |

up
Asked MCumall ebay webshop for help or warranty = no answer
If you can tell me how to repair it i can certainly do it, but i need to know what to do ! !
Is it a capacitor problem? a memory problem?
When i try to burn eproms larger than 512k it fails everytime.
Best regards and please help me ! |

check if programmer read correctly.
If reading is not good, then you need to check all pin contact with the programmer ZIF.
