hello good how are you all this way I want to lose help to those who can give me a hand with this problem k I have with this tv haier model htx14s33 as I said in the title does not turn on or rather does not do anything or has any part in part and not ce and where to work could you help me polfa this tv use this ic C4458 this is in the regulator area but stop a horisontal exit this was bad but I changed it for another but the k I put it does not have the same numbering I think k is why k no turns on

Friend, this is the diagram, now the transistor that is the same is the same as the original discharge and resists well that there is voltage in the leverage filter

no friend is not the same that I put it is C5299 I think that is my problem that I have no voltage

Friend but I compare that they are similar? If not, I recommend the original

Friend below the partner manolo put you replacements of the flown transistor now I recommend checking the surroundings of the transistor can be flown something else

Diagram here: http://diagramas.diagramasde.com/televisores/HTX14S33%20HTN13R12.pdf Check the good condition of the components in the primary stage of the source. And in the + B line the error amplifier and optocoupler in the secondary stage. Make sure there is no "short" in any of the auxiliary sources of the Chopper transformer. Until stabilizing the + B free of its real load to the source (TSH and FBT) and place a spotlight as a false load

I miss which is the error amplifier

Hello Friend. the replacement of that transistor c4458 is - 2sc4429, - 2sc4430, - 2sc4460, - bu2520af, - bu2525af this is just enough to replace that transistor of the source. Cheers

Tell me the C4423 is not the same, that is what I have in the workshop but I don't know where to measure the problem.

friend. according to the data in contracted those are the replacements do not put a k because you can make a mazon of elements

greetings I have years working this no but I did not publish ... now with his tv saying that it has no voltage anywhere already measured in 507 c 507 filter 250v 470uf, the transistor he put is similar to the c4458 a little more robust in amp and watt something should do if it has voltage at c 507 check the v512 2sc3807 if it is short the v 513 is not polarized .... attention! when c 507 is devalued it puts short av 513 has already happened to me

hello friend sorry for the afternoon and the TV turns on but this is rejuvenating the 470uf to 25v capacitor and is heating the 220uf to 160v capacitor could say goodbye polk this is happening to me

Greetings that indicates excess voltage still has to do with regulation
