Hello friend, comment model and chassis number yq, review or measurements done on the TV ... ok ... greetings!
friend I'm not sure but I think it is a j6 or 56 voltage chassis in the primary only in the 174 volt filter that goes to the input pin of the regulator and take out the microphone and change the regulator and the sub-regulating comb where there is no voltage either in the primary filter
colleague: you don't mention the model or chassis ... look closely if you can decipher the chassis ... samsung doesn't use those chassis number ... for now remove the trans, from the board, and see if it appears tension in the + b ... ok ...
good friend nico thanks for your attention to my problem I tell you that already discard the micro lower the ht everything measures well the unicovoltaje that I find is the one that enters the input pin of the regulator on the wavelet says KS90
The truth had not had that fault and I can not find where I put three regulators the same, the regulator is 5Q0 765RT. some observation that something I missed. thanks
KS90 says on the plate and the voltage is 172 volts. The normal primary filter is normal. For some reason the regulator does not work and therefore the source does not work either.
What is the sub-regulating comb? What do you mention? identification has ... q, position number has on the plate ... it will not be KC9C chassis ... if you have as a source regulator to lc801-KA5Q0765RT ... notice if it resists the starting voltage on pin3 q, it comes from R811 and 812 from the line voltage of 172v of the C801 in the primary of the source ... ok ... you took the trans, from salt-hor- of the board ... check if you don't have any diodes in short at the chopper..ok ..
Another is that I have only one card, I don't even know the TV model. find out the tv model and it's CL - W21M40MQ
I already checked the components of the primary and I find nothing abnormal the comb is KA 7632 and is the ic 802. But friend is that the strange thing is that it does not hook the standby and there are only 172 and not a volt more anywhere. Crazy friend. My head is in turmoil. I can't find logic. Do you suddenly have the diagram?
Good friend thanks for your kind attention.
I can't find that model on the net ... I only have the mod, samsung-CL-21M40MQ - KC9C chassis ... look maybe there is an error in the model q, you comment .... I asked you what the comb is regulator q, you mention ... q, n ° has ... q, position it has on the plate ... you have q, give more pressure ... ok
colleague: I leave the scheme and see if it is the q. corresponds to your plate .... if it was useful, value the contribution ... ok ... greetings!
