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.

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
:super:

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
