good morning I have a NOBLEX TV of 29 "model 29TC676F, according to the lady after a power outage she went to turn it on and made a spark in the ignition button, I took it to the workshop and uncover it found the fuse in good condition but the electrolytic of 270uf X 400v in short, the fast cutting diode 603 in short, the zener 616, the resistance 603, the ceramic resistance 602 and the zener 602, all in short, start by taking out the fast diode 603 that was effectively short but when desoldering it, the electrolytic was no longer short-lived, so I left it on the plate, if the other components were failing then I bought them, before welding them I check all the primary part of the source and I don't find any component in poor condition , I check the ignition key that the poles do not cross and everything is fine, now when welding it again it makes a slap and the same components are shorted except the zener 602, for that reason I need your ex I have the opportunity to ask you a couple of questions since several days ago I have it and I don't find the fault, even if I check the source several times, first know if the zener 602 is 6.2v and the 616 is 8.2v as They told me in the electronic after asking where I'm not diving well? Can the fault be in the secondary? also the horizontal output TRS check it and it is in good condition, well thank you very much for your time and for sharing your knowledge a hug

The D616 = 18v. See sheets of electronic parts in the manual. Verify that there is no short circuit in the secondary stage of the + B source and auxiliary sources. Again check the good condition of the components in the primary stage of the source change the oscillator IC. Unlink the + B from your actual FBT and TSH charge and place a spotlight (70w / 100w) as a substitute charge. Until stabilizing + B, keep the focus in that position To avoid sacrificing spans of components connect the TV with a series to the AC line input of about 150w or 200w
