good afternoon companions I need your help with a premier tv the model tag is not brought by the chassis is the ph08k -n35 the problem that this tv has is that it damages the horizontal shortly I want you to help me what will be the replacement of the flybac bsc2501n4010d I thank you for your collaboration thanks colleagues

good day friend victor sorry for the delay in responding yesterday I was looking for that replacement that I gave in the electronics and there is not very difficult here to get flayback I have at hand these are the codes bsc24-01n-40 bsc24-01n40006evr bsc2401n4004a this are the code that has this flayback or if it has the diagram of this flayback to adapt it, comrade victor this tv came to me with the adaptation of a culer because I imagine that he heated the tsh cloque another tsh and heats it too much thanks for the help friend

that such partner got another flyback that I bought another colleague the original flyback but the fault is the same heats the horizontal and damages it that another thing you suggest me friend the yoke measures me vertical 7.8ohm and horizontal 3.3ohm I need your collaboration friend thanks these are The jumgla chassis components tda11115psn3-3mcz regulator strw6554a audio tda72665a tsh d1557 vertical la78040 thanks

Change the filter of the driver, which filters the supply voltage. Or if you do not try placing a resistance of 33 ohm between base and mass of the horizontal output transistor. Did you change the collector capacitors of the horizontal output transistor?

as this partner change the polyester layerers the red ones that are close to the tsh this tv is 110v in the + b but I get 118v change the r and the diode where the voltage of the choper comes out and the same boy remains to change the filter and commented partner and place the r of 33 ohm companion but with ths put I do the test

If you place the resistor, you must have the horizontal transistor and turn on the TV to see if the transistor is hot. If the flue is high, the tr or flyback will continue to burn. Check the regulation system of + b, optocoupler or tl431 if bears greetings

good day friend victor can you do me the favor of making a small diagram with respect to the resistance or I put the land and based friend and excuse me friend thanks

between base and issuer, if this is grounded or base and land.

I put the base r and the flyback gnd friend and still the same I place the r between issuer and base partner

lower the source voltage to 110 volts or + b.

change the diode and place a r of 1ohm that goes to + b but it gives me the same voltage as I do to lower that companion voltage and also change the optocoupler that you suggest friend thanks

so it will never go down, you should check the optocoupler circuit, if you bring a transistor or a reference diode like the tl431 connected to the + b by means of resistors. check that

friend victor the tl431 is a pnp transient I was rebelling but I don't see it

I think friend that this fault will be acted by the yoke because it has a sound that is not avitual it feels as if it were snoring that is why it will be hot tsh you will have diagram of this tv friend thanks

The TL431 is an adjustable voltage reference regulator, it is not a transistor. The circuit of that TV is not achieved.

Up there pass the regulator circuit of the secondary of the source, see if your TV brings that circuit, it has pre-set to regulate the voltage.

good afternoon friend victor excuse me the delay in responding I was a little broken in health and I could stabilize the votage of 110v change the tl431 adjustable and the r of 100k and 150k and the voltage normalized now is that I do not turn on the tv in stamby it is of 60v I give it power and it goes up to 110v but the flyback does not oxidize me it tries to start but it sounds is the yoke but I don't have another yoke of that model to try friend and thanks for your help
