A1200 RGB Port Woes :( - Page 2

rkauer · 05 October 2009, 18:14

I managed to burn the +12V line resistor from the RGB out of my A1200 and an A520 at the same time just bumping the case.

Disconnection while devices are running is bad for your pocket...

This is my thoughts too kipps.... clearly his composite source is working,

But this is supposition at the moment as I dont have Nathans schematics, he would be best to comment, so please dont panic Fingerz though LOL,

Just a quick one.

If it turns out that the mobo is damaged, since it still works via composite, A520 & DCTV...can I assume the damage is post-lisa & it'll still work with an Indivision AGA?

If that is the case, I could just swap mobos around, as my other A1200 (typing on it right now) has an Indivision in it.

PZ.

p.s. If the A2000 & A1200 are suffering the same damage, might that be a good explanation as to why I could never make any configuration of RGB-to-SCART cable work on the A2000?

You probably just have a problem on the +5V rail of the RGB port (on both machines).

But I already tested it man: +5.06V
