Intervideo Dual Frequency No vertical
« on: December 30, 2019, 02:55:50 pm »
I was doing a recap on a Intervideo Dual Frequency and when i tried it again the only thing i get is an horizontal white line.

I already did all the recomended

1. Resistor R153 = 4,7 Ω 3 W.  - TESTED OK
2. Integrated Circuit IC104 = TDA1675. - TESTED OK but changed it
3. Adjustments Board K105, see fig.14. - doesn't work
4. Diode D124 = BA159. - TESTED OK

What should i do next!? I so lost... please help me!  :cry: :cry: :cry:
