comment more tendons of the source regulator. Pin 1 - 3- 5.
If the original regulator was burned for sure you have some zener in the furious evil.
Change for safety no matter how well you measure.
good afternoon don Luis thanks for commenting the regulator's intentions are
pin 1 = 165v
pin 2 = 10 to 12 v oscillating
pin 5 = 87 to 90mv oscillating
I had forgotten to comment that when replacing regulator also replace zener and electrolytic
I went back to measuring everything in the pin circuits that it tells me to review and everything is ok.
replace 27v zener dz802 diode only by discarding because it mediates well and electrolytic c804 from 33 micros at 50v but there was no stabilization
Pin 2 is mass. Surely you got confused.
Unlink one by one the source outputs and the flyback pin where the + b should arrive
Connect all outputs as they were minus the flyback pin. And place in the + b a focus of 75w to 100w. And measure.
Change the TL431
good afternoon don luis change the ic803, hise the light bulb test in + b, the light bulb turned on dimly, notice that the standby led also lit, with the television connected to the series and with the bulb in + b these are the measurements :
+ b = 60v stable
12.5v source = 5.7v stable
stable 13.5v = 7.2v source
primary filter primary source = 152v stable
pin 1 regulator = 151.9v stable
pin 3 regulator = 10.2v stable
pin 5 regulator = 1.7v stable
If it does not heat anything, remove the series where you connect the TV and leave the + b to control the voltages again and see if they do not heat components such as TSH - flyback - vertical. If it is warm and tensions well direct test.
How much is the focus that you put both at the entrance and in series on the + b?
with tv plugged in direct current and focused on + b
+ b = 60v
12.5v source = 5.7v stable
13.5v source = 7.0v stable
primary primary filter = 163v
pin 1 regulator = 163v
pin 3 regulator = 10.2v
pin 5 regulator = 1.7v
all stable
I already turned on thank you very much to all the people who gave me help especially to the teacher Luis Tartaglia who is always ready to give help to those who need it God bless him, please send message to solve and close this topic
