Мои познания в ремонте данного вида техники: Начинающий (делаю первые шаги) Наличие схемы: I have no diagram Dear Fellow Forum Members!
I have three Renault car radios of different model numbers with the same problem: no sound, but all other functions work. All three units have been measured, the output stage is good. HARN1004 and HARN1005 units have the same manufacturer and almost same motherboard, but the AGC-1220RF (ARA-1230RF) has a different manufacturer and motherboard construction. Have you ever encountered such a "no sound" case? Where should we look for the problem? I'm not an electronics mechanic, but my friend is and he's already spent three hours on it and can't find the fault. I would forward your answers to my friend. I would really appreciate your help, because I really like this type of car radio, they are my own radios.
The same Renault bluetooth units, but different manufacturers: - HARN1004 RV3S-R3020E-P Made by Humax, Poland in 2018 - AGC-1220RF (ARA-1230RF) Made by Daewoo, Korea in 2012
