| SEMP TOSHIBA | 23L2400 OU 40L2400 | Tv nao liga so stand bay aceso | Check if the n805 is regulating 3.3v, if it is, check if tsound is 3.3v in the n807 because in the stand bay you cannot have this voltage if it is 3.3, directly replace the n801 and the TV works normally | N805 eco 3.3v in stand bay the n 807 can't have the 3.3v if it does, just replace the n 801 and run for the hug | beto eletrotec |
| SEMP | TV2134 SK11 | The TV has an ok audio output and all voltages, but tsound is no sound. This version of the TV has the IC851 analog audio equalizer on the board near the varicap. | Ci defective equalizer, replace or if tsound is no other add the following components to the board (q801- brc1815,r804-470Ω,r739-56kΩ,r740-1kΩ) the jumper j801 and j802. | The TV returns the sound normally with the audio equalizer acting if the ci is replaced, if the modification is made the sound returns to normal (volume acting) but the equalizer no longer works...
