hi

so if any body have a ckt diagram of SM-230 (SunWin)..

sunwin pctv model 230 device faulty its audio ok but when connect to monitor no display. Monitor and cable ok. When i take output from vidio out lead and feed to TV it displayed. kidly any one send me fault to recover the fault...
Salam friends, i am having the same tv tunner, but the problems are different. There are two problems, first is, that The audio is completely gone. Either it dont play the voice via its own built in speaker, nor with the external amplified speakers.Its speaker is okay. I took the card to a repair shop, but they said its processor (may be they mean IC) is damaged, thats why the sound is gone. But i dont agree with them. 2nd problem is that when it is connected with the minitor, it dont display the picture. may be its problem with the minitor cable. With the tv its ok, but audio is not.
So plz tell me the solution. i am really affraid about it bcoz i cant buy another.
