tv parker with vertical problem
friend that chasi uses the UTC78040 and STV9302B which are the same now he is fed with 15 v positive by pin 2 and pin 6 and by pin 4 with -15v measures those voltage that are present these voltages are from that of pin 12 and 9 of the source transformer by means of a diode in each line check and comment
In this TV it is fed with 13 vol positive and 13 vol negative are indicated in the outputs of the transformer on pin2 I have 13.46 vol and pin6 12.77vol pin4 -13.48 vol I think that they are the output pulses or vertical input how many vol they measure the other pins I already put the utc 78040
He touches the pins and only moves a little Asia up the line ahh the TV brand is premier aviated me confused with the brand but the other data is correct
In pin3 of the vertical I have -12.5 volts is this normal? and on pin 14 and 15 I have 1.04 volts and I already changed the jungle and I still don't care
If I remove the vertical in the jungle, it measures 0.90 volts, which is almost 1 volt on pins 14 and 15
Thank you, her ... the diagram in the two lines of the vertical pulses would only help me only a and two r of 100 hom .. and the che and are well and those that are close to the verti..the yoke is fine I measured it and it measured me 10 hom..in the verti line .. I already replaced it too
Hi, her ... I tell you, I already repaired the TV. As I still told the TV, I didn't bring the vertical because it was already revised because the R459 is changed because right here in me I repair I could find the diagram and then I noticed that it was of another value I had an R of 180 hom and the one that is used is a R of 1.2 hom I replaced it and then the TV opened normal ... I suspected that R because it was noticed replaced but I noticed another chasi peer and then I used that R 180 hom but in this tv no THANK YOU herm..by giving me your help
