Oh forgot but you can send the boards to me and I can check them. I will charge nothing just for fun  |

I am thinking perhaps you crossed the grounding wires and not the rv and bv?

I dont think so. He would not of lost the blue movement when he cut the red v wire.  |

Yes could also be explained if somehow the blue convergence is subtracted from the red. That would neurralise green adjustments. So he could be very close...
than cutting the blue wire might work.

Found a bad solder in a transistor.
Perhaps I cut something during tests.
Now the red grid follow green in N/S adjustments but it's really unstable.
Now R22 stay cold but R122 goes overheating.
This is a never ending story

Didn't Curt have a replacement board for you?
R122 is in the horz section. Ohm test R120, R121 and R122. You have to lift 1 leg on each to test correctly.

No he don't have this board. If someone have this board here will be welcome.

Meter at 200 ohms
R122 = 7,4 ohm
Meter at 2000 ohms
R121 = 275 ohms
R120 = 275 ohms

Meter at 200 ohms R122 = 7,4 ohm Meter at 2000 ohms R121 = 275 ohms R120 = 275 ohms Compare the temperature of R122 and R103 to R182 and R163. Make sure all your convergence and geometry setting are at mid point or neutral. |

Temperature?
The settings are always in default

Compare how hot they are. You said overheating.

With legs of resistors lift?

Youve come this far Decibel, doing well mate  See it through buddy! |

With legs of resistors lift? No no no. You said this: "Found a bad solder in a transistor. Perhaps I cut something during tests. Now the red grid follow green in N/S adjustments but it's really unstable. Now R22 stay cold but R122 goes overheating. This is a never ending story" How hot is it? Compare it to the other resistors I named. "R122 and R103 to R182 and R163" |

Today another convergences board delivered in my home. I tried it quickly and I noticed the same issue described in a previous posts: all grids tremble especially in the edges of the image.
This board come from Redfox so I must to assume that it works perfectly. If I remove the jumpers of this board, the trembling disappear.
