Flyback
Pictures of my Magnavox. Blue arc can be seen at top on right in picture three. Picture is faded.

Better Picture.

All pictures are mirrored, taken with an apple macbook pro, so ask them why.

Grease fixed flyback. Still no color no sound.

Did you physically remove each module when you soldered the mother board? And, you did resolder the connections on the modules?
You shouldn't have to redo everything on the boards. It's just the high-current connections that flex and break Sometimes, you can take some fine sandpaper and clean up the stakes on the mother board to get a better connection to the module. When you turn on the set, do you get a thump sound in the speaker? That would tell you if the amplifier module is at least working. Examined the module for discolored parts? You dont have a schematic, do you? The FBT also supplies power to some of the modules. Your no sound problem could be something as easy as a fusable resistor that is open. Best of luck. I never really had alot of issues with these Maggie chassis, other than the module and mother board soldering problems, and the occasional tripler, and/or horizontal output transistor. |

Does not make any sound. Does anyone have a sound or chroma module for the t815-09? I also need the remote receiver module. I soldered every pin on the main board and all the modules. Picture also pulls a little to the right, with cut off graphics.

Which resistors and transistors near the flyback should i replace?

Does anyone have parts for the T815 chassis? Help would be most appreciated.

I need the verticle oscillator module. I believe the part number is 704200-3.

Replaced all the capacitors on the verticle oscillator module now only have two thirds of a picture and its snowy.

Removed and reconnected some parts. Picture is back like it was, no color, no sound. I believe the tripler is weak. Could this be the problem?

Triplers dont get weak.

Why still no color no sound?

Look for a common voltage source between the sound module and the color module. Most voltages on that set (I think) come from the running flyback windings, thru a diode, and a low ohms resistor before being fed to the circuits.
If you found bad capacitors on the VERTICAL module, Don't you think other modules need capacitors, too? You're having problems that I rarely saw when I was working on these sets, unless something odd had happened, like a lightning strike.... |
