this tv came to me with the vertica fault ... that had burst, and ps does not have the code of the vertical dica ... according to those models I put the LA78040
and nothing to do ... then I put the STV8117 and the problem continues. I do not know if the value is adequate .. or not since I have the vertical but there is no image and it comes out as if the zocale where the canyon is going to go wrong .. however I already checked that and it is brighter inside .. Any suggestions or anyone knows the precise value model CTV-1405

is a 2139US Chinese model with generic chassis PH08KX-N35 says it is daytron ..}

That is my chassis I say Samsung .. to be Chinese .. but that vertical that mentions there I put the stv8172 and I stopped smoking very fast .. I checked the voltages .. and is ok +. -17v. However, I have noticed that the diode of -17v overheats at the same time.
I have the doubt that this integrated is not of this model since I check and there is no

Of course I measured or replaced the filter cap C562 and C563 of 1000 uf / 25v of the + 15v and -15v of the source.

Hi Mayqui, that chassis carries the UTC 78040 or STV 9302 B. The voltages in its pins according to the circuit are: Pin 1 = 0.8 v - Pin 2 = +15 v - Pin 3 = - 9.8 v - Pin 4 = - 15 v - Pin 5 = 0.2 v - Pin 6 = +15.5 v - Pin 7 = 0.8 v - Check the vertical circuit components. (C406 = 100 uf / 25v - VD401 = 1N4004 (Change it even if it is good) - C405 = 220 pf - C404 = 0.22 uf - C403 = 22 nf - R459 = 1.2 ohms 2 W - R460 = 150 ohms 2W goes in parallel with the vertical yoke - R403 = 2.2 K - R404 = 1.5 ohms - Comment the results.
