In a light emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called " electroluminescence ". The wavelength of the light depends on the energy band gap of the semiconductors used. The bonding Machine is designed for LCD/LED TV Panel repair, which can solve the problem of ACF/COF/TAB fault, the function of the bonding machine is replacing, bonding, re-bonding COF/TAB on LCD/LED panel glass side and PCB side as well. After that you have to check all the panel voltage which is necessary for drive a TV panel. 4. Check CLK signal. Some times we get this No Display sound ok problem because of CLK signal missing on the panel. So check this problem also. 5. Check CKV signal. Many time we get this problem for CKV signal.
