Press start power relay knocks but disarms and flashes 4 times successively. | I did a scan on the board and it was constant that tsound was no +b so I found the c647 of 25v by 47 on the primary a and it released the +b but it was still in protection and I did a scan on the secondary and found the r592 of 0.33r open and c617 of 160 by 33 without capacitance. I replaced it and the TV worked perfect. | Francisco Melo -Parintins-AM | |

The table turns on, the signal from the primary (1) and secondary (2) input microphone (mic) normally comes out through the l+r output, but noise appears at the output causing interference | Leaking capacitors were identified (c50, c45, c38, c44, c37, c18, c16, c76) mostly 10uf by 25v, problems also in the lm339 operational (ic7 and ic10), in addition problems were found in the dual channel of the ci 4580n or even though it did not have the voltage for charging the capacitor of -21.7v, its output was 0.07v | The series of capacitors such as (c50, c45, c44, c37, c18, c16, c76) were replaced, the two operational lm339 (ic7 and ic10) were replaced and the ci 4580 typical series n was replaced. | marcosxpd154 |
