Good colleagues have little experience in the repair of televisions, I need help with this daewoo TV which has the fault that when giving the power order it does not turn on, this according to the client was working I turned it off because it was raining very hard and then when He went to turn it on again he did nothing, this came with the failure to turn on (or the standby LED) after uncovering it and checking the source I find the blown fuse I proceed to change it I connect it to the network with a bobbin in series for protection and the LED on, the problem lies that when giving the power order it did nothing but the LED goes out and stays off and if I turn it on again and the LED turns on again, check the output voltages of the transformer on diodes D813 : 8.2v D807: 117.1v D841: 41v both standby and power in memory i have 5.1v in the microcontroller (DW863428V) I have the 5v of pin 8 check the horizontal output transistor and it is fine What I could see is that the 5v of the jungle (LA76845) of pin 25 are not present either in standby or when giving power and these are responsible for the horizontal frequency if you can help me with this fault I would appreciate it

Friend, the voltage on the D813 is very low, you must have 12 volts so you don't have 5 volts on pin 25 of ic I101

Isolate the + b, and measure how much it arrives both in standby and when giving power. Comment

Hey, I have a doubt, does the serial bulb not cause a considerable voltage drop for TV?

Unfold Pin 25 of the jungle to see if the 5 volts are restored. If so, the jungle is the problem. If not, you should check from the source. At the output of diode D813 there must be 12 volts (you measured only 8.2 V.) Of those 12 V, 5V is output through transistor Q805 = KTC3205 (PNP). The 12 V also supplies the integrated audio amplifiers (TDA 7267A). It may be one of them that is lowering the voltage of 12 V. Do these tests and comment the results. I am at your service. regards
