Burnt resistor on A1200 motherboard - Help!
« on: January 14, 2006, 06:21:26 PM »
I'm not sure if this is critical or not but I'll post it anyhow...

E232R to the left of the IDE port on my A1200 2B board has burned a slight hole in the substrate of the board, the resistor (4R7) has removed itself through heat.
Before I replace it does anybody know what this resistor does? My best guess is that it's something related to the RF modulator however I really want to be sure.
If it doesn't affect anything else I'll remove the RF modulator from the board.

Thanks all.

I'm guessing the modulator is duff, when I tried it back home in England I couldn't tune it in at all which would explain the resistor failure - whoever owned it before me had taken a screwdriver (Hammerdrill) to the trim pot for some reason.

I think I'll remove the modulator, I can't use it over here (USA) and it'll give me a little more space for my IDE cable project :)

VGA port, that's a great idea and it'd fit perfectly.
Now all I need is an internal scandoubler.
And an accelerator, more RAM, 3.1 ROMS, OS3.9........

I ought to hawk some of this PC hardware I don't really need anymore.
