Good morning: Do you know the number of chassis that the TV carries? ... It has to measure tensions, what is the integrated audio amplifier that the TV carries? Find the datasheet of the same by the WEB and try to identify the pins where you have to measure the voltages that feed it ... Finally you can try to solve the fault by changing it.
friend neg2013 the chassis number is 4551-2010101b and I do not know which is the integrated amplifier, I think it can be the 87ck34bn-3326.I am relatively new repairing tv, I would appreciate all the help you can give me and guide me in this fault
Unfortunately the data that comes, at least I do not generate any results if I enter them in Google Chrome. Except for the second data. (87ck34bn-3326) This is the microprocessor of the TV, it may have implications with the audio, but it is not the audio amplifier ... I suggest you avoid many dramas, and get your TV to a technical service. For my part it's all ... Best of luck
