Tube TVs
Doubts about adapting a flyback
hace 5 años
hace 5 años
I have a PREMIER 20 "TV with PTUM01 chassis which has damaged the flyback that has the number FSV20B013 and I can't find it anywhere. I have looked for replacements and not even in other workshops are already desperate. Well the query is , I have a 21 "Samsung TV which has a flyback with the same voltage outputs but the B + of the PREMIER is 135V and that of the SAMSUNG is 125v. Could that be used? What problems can it cause if I try it? Is that 10V of difference too much?

Thank you for your response but I have looked for it in all these ways and no electronics house has them or in workshops I find it. They tell me they are already discontinued.

I am from El Salvador. Then you can not use the least tension. And what would be the damage it would cause? In the TSH or the flyback itself would burn?

Hi. I would place it and more in your case that you do not get or replace. And you inform the client of such modification. If not, I would have to unsubscribe from the TV. due to lack of replacement.
the other you can try to do is reduce the + b in some way. It would have to do in diagram. How to make that reform. In some of them it has a preset of adjustment of + bo the resistances that work with the optocoupler are varied.
I did it by placing a flyback of a goldstar 154 / 77j tv that works with 112 or 114v of + b, on a SLIN 20 "Hisense TV. That worked with 125v of + b. I reduced the + by and modified small settings by entering the servi mode .
I hope it helps you. It is another point of view.
