As soon as it turned on, it activated the protection made up of q852 to q855 and relay rl801, that is, q857 was active. | I lifted the r567 (7w 1Ω) and the problem persisted. the problem was in q857 which had an undetectable leak at low voltages, however as the voltage at its emitter reaches around 150 v, this same voltage reaches the collector without causing an overcurrent in r877 | Replacement q857. I replaced it with bf423 which is equivalent to 2sa1018 | PASTOR |

This TV arrived to me with the following defect, it turned on and then turned off, when I lowered the brightness it worked normally but with low brightness. | After a lot of fighting with the TV, I discovered the defect was a q503 transistor near the flay back, note.. you have to remove it from the board, and everything will be normal, great! | diego lima nova timboteua PA | |
