Test accelerometers 300 v, the main voltage is 140 v, filament light. Is 3 guns in the globe, the accelerating voltage, light, but light is not normal, no images, no sound, just the screen are isomorphic, (just behind the deflection coil to pull out a little bit of) so I wonder if deflection coil is not good, only lead to the problem above.

Then think of I have just received the machine, there are a lot of dust, the owner then told me his TV has six years have not completed, but sometimes can open up at home, have not open again, so I suspected that is likely to be empty welding and places where there is poor contact Then I went over the fly ash, in the place where it is to put the two boards connect, all clean again (because this machine has two large pieces of circuit boards, connect place is made of iron stuck), and the decoder repair welding, then I searched a boot, then back to normal.TfXservice manual download site
