I have magnavox 20MT1331/17 and after several weeks of research I decided to attempt to mod in component input as outlined in this post: viewtopic.php?f=6&t=56155&p=1440296#p1440296. After many, many checks with a multimeter, I believe I've wired it all up correctly. However, the CVI input option never appears, no matter what value I set in the service menu for OP5. My biggest clue thus far is that while the service manual linked in the post I was following says that a bit value of 8 on OP5 should enable CVI, it actually enables an AV channel labelled FRONT, which the manual says should be on a bit value of 16. And 16 does nothing, even after attaching the blanking pin to 8V with a surface mount 1k resistor, as instructed.
Am I just possibly on a different firmware that doesn't support component and therefore SOL? Or am I missing something? Thanks in advance.
For OP5 try to input 204.
Also you shouldn't need any other voltage at the blanking,think it has voltage by default.
