It sounds more like your main board was toast and rather than properly diagnose it, you threw a print head at it which didn't fix it. Now you want to disparage a decent honest vendor in an attempt to get a free fix. Do some research, these printers are designed around the printhead and not vice versa. Another thing that will fry boards is not properly discharging capacitors before fooling around with them. Be a gentleman here, your goal is to get your printer working and I guarantee they can help you but if you keep on they won't and nobody can blame them
