@HiFiofTLT: Köszi! Viszont ha csak az EM4 pusztult meg, a Composite kimenetnek jónak kellene lennie.
Vagy mindkettő EM rossz, vagy ahol a modulátorban a két jel még közös, ott lesz a gond
Eng: Thanks! On the other hand if only the EM4 is defective, the composite signal should be still OK. So both EM should be NOK, or somewhere in the modulator (where the two are still originated from one color signal) should be tha issue.
Unfortunately none of the EM3-5 visible on the previous photos.
This area could be an area of interest (it is from a saved big resolution MOBO picture from my collection)
BTW (not directly linked to the topic) maybe I saw on the previous photo a not 100% soldering (maybe I am just not well evaluated, but you can compare it to the above picture):
