Re: 6100 Deflection problem

Ok, bear with me I just got my scope last week. Its a Tek 465. I bought it to help me fix this game.

Where do I hook my scope to on the deflection board ? The deflection board I have is P339. Where are the yoke protection fuses ? The other board numbers are HV P329, Neck P315. I forgot to add I have the LV2000 installed also. When you say to unplug the yoke. Do you mean unplug P500 and J501 from the neck board ? Sorry if these are stupid questions. This is my first Color Vector and I don't want to screw it up. The G05's are alot easier.

    I have a 6100 that was dead when I bought it. It's in a Gravitar. My problem is, I only have delfection in the upper right of the monitor (X+ and Y+). I have swapped the transistors to both sides. No change. The spot killer isn't lit. It's not blowing fuses. I did the following on it.

    Full cap kit
    Reflowed the wires for the transistors
    Checked for cold solder joints
    Reflowed all the conector pins on the deflection board
    Tried to adjust the monitor using the pots on the board
    Double/triple checked all of the chassis transistors (they're good)

    I checked the X and Y out on the Gravitar board using my scope and game looks good. It has full deflection. I was able to finally play a game that way. I'm thinking it has to be the monitor. Any ideas on what I'm missing ?

  Did you check the yoke protection fuses for continuity/bad grip? Also, you can use you scope on the deflection board to see if the signal is getting through.

  Remember that XY monitors are virtually identical to audio amplifiers - roughly the same drive and frequency response is just a bit higher...

  You can run the monitor with the yoke unplugged for example (no load condition), just be sure to have the driver transistors plugged in.
