If the 4-lead safety cap opens and the internal interlock does not break, the HV will skyrocket and literally blow the neck off the CRT.

I lost a beautiful Zenith console this way once. I turned it on to see what was up, and heard this SNAP and a rush of air. The neck snapped at the bell, and the yoke and convergence parts all let go and fell.
Your no color and no sound issues could be what I said before. Have you got a meter? Schematic? Schematic will help you. |

I have a meter. No schematic. I have not been able to find any bad resistors. Have replaced most capacitors. I have not replaced the ones on the main board.

Any ideas will be appreciated.

Get a schematic and use that meter that you have.

I think it is a .68 resistor on the retrace board or a .69. Hard to find. It is one watt, brown, bands are blue, white, silver and silver.

Was not resistor and since i have no sound i think it could be the flyback. Does anyone have a flyback for the T815?

I've never replaced a flyback on the T815.

How do you fix no sound? Also has no color but sometimes flashes in for a second.

GET THE SCHEMATIC if you cant figure out whats what. The color is something else.
Didnt you have a picture at some point? Then you soldered up the grounds? Then no picture? Recheck your work!!! Last edited by holmesuser01; 09-14-2012 at 08:11 AM. |

I still have a picture, once i got it never lost it. It is just black and white. Pulls a little to the right.

Anyone have a flyback for the T815 chassis?

You should really get a schematic and measure the voltages around the sound and color sections before replacing the flyback. Have you tried SAMS 1860-1? It is available on samswebsite.com for $22, instant download (I have no affiliation with them).

Does anyone have experience working on these sets?

I did authorized service on Magnavox TV's and worked on plenty of 815 chassis. It was a good design. Once I soldered most of them up, they rarely came back for service again. Get the schematic and take readings.
