greetings jose Luis thanks for the contribution certainly the integradotiene the absence of the 180v due to a resistance r450 q power was open but I changed it and the integrated put it short, after that I took out the integrated and put the resistance again and mark me 190v I don't know if that's why I wanted to know the value of the resistance seems to be 1 ohm and I don't want to burn the integrated one again and be sure of the fault
ok nicomena thanks for your attention, because that's how it is a fuse resistor replaces it and the integrated I start to smoke it take it out and on the pin where its + b arrives and the one next to it is in short bone it has continuity on time i already have the another integrated but I want to be sure that it doesn't have another damaged and vulva element to happen the same
the integrated can not be shorted xq, reach 180v ... for that you should check the socket of the tube well and measure if there is no short even the tube cannons ... to try to avoid q, get damaged the tda is a bit difficult ... you can try to levaltar a leg of the L503 q, it is in the socket of the tube and instead connects an R of 10kohm if you see that, the R of 10kohm fumes follows the short and you must turn off quickly ... this way you may not burn the tda ... if it does not smoke try another 4k7ohm and see what happens ... you can also try taking the socket out of the tube and see if the same thing happens
I don't know about it: but if the R450 burns you, you should check the socket well before assembling the new tda6109 and make sure that there is no short film ... x the photo that appears, I don't think so. be the tube, but you have to, check the socket well and to try to prevent q, do not burn back (you can not assure) ... as I said raise a leg of the L503 and instead weld a R of (10k ohm) and see what tension there is on pin 6 of tda6109 ... if there is something you tense you change the Rde10k x one of 4k7ohm and then change it back x one of 1kohm and so you are measuring on pin 6 of the tda6109 if the tension is happening ..
I already solved my friend by changing a 10f filter that goes in the 180v line and the image was repaired
Well buddy: I'm glad that you already have the TV working ... (congratulations) ..
regards!!
