Hi to all Like a wise man thought me, sometimes we need to take a break from projects and do someting else or we get frustrated and this is what i did. i set the TV aside and started working on other one of the ones i bought...this one is a x19 t 610 It has a tube tuner for VHF and its turret type, it has a continuous UHF tuner and its solid state. The tv is all vacuum tubes except the second video IF wich is a AF132 germanium transistor and the raster stabilization wich is a AC125 When i first tested it it had no High voltage at all, completely dead, no raster and not a single spark I checked the Horiz.oscillator and it was running at about 20khz, way too fast but it should make high voltage, then i checked the grid of the horizontal output tube and the horizontal drive was present and with good amplitude,next i tested continuity on all the flyback windings and everything seemed fine but something was loading down the flyback.. So i suspected a leak im the Hhigh voltage winding...i replaced it and the result was the same. then i looked into the other philips tv the one with the vertical problem and the flyback were identical but the pins were totally different. but with a bit of tracing and rewiring i fitted the entire flyback on this one. After tweaking the horizontal oscillator coil for the right frequency it works very well and with all the original capacitors. i still want to replace some electrolitics and clean the controls and do a set-up. Dateianhang: here is the x19t610 with the replacement flyback fitted Dateianhang: some rewiring work on the red circle area Dateianhang: other shot of the work done Dateianhang: this is the tv with the vertical problem that donated the flyback.. Notice all the yellow capacitors on the vertical section that i replaced while trying to fix the problem this tv died for the other one to live. i will store it for parts |

Dateianhang: still need to set linearity, size and centering but all the controls work |

today i dissassembled and cleaned the tuner contacts, sprayed the potentiometers with contact cleaner and did a basic setup. its working for 2 hours now..i will turn it off, looks like it passed the test Dateianhang:
