The invention discloses a television image quality debugging method and device. The debugging method includes the steps that an image quality update request sent by a television is received; whether a debugged image quality binary file exists or not is queried according to software ID of the television; if yes, the debugged image quality binary file is sent to the television, and the debugged image quality binary file replaces an old image quality binary file in the television. According to the television image quality debugging method, the whole debugging process is achieved through a computer, high efficiency is achieved, it is not needed to manually record multiple pieces of data or manually input xls or manually generate PQ bin, errors can be reduced, time of other engineers does not need to be occupied, and engineers debugging PQ can conveniently debug the PQ without being familiar with software codes by themselves.
