A1200 with green hue

stainy · 29 October 2006, 19:36

Just swapped a 600 for a A1200...

Apparently... output wise it has a green hue to everything..
RF and RGB I`m told... whats causing this and more importantly is it fixable!

You sure they said RGB and not "Composite"?

If RF is wonkey I would imagine that Composite would also be broken, but RGB?

I have an A12 with a problem with green RF and Composite, the RGB is perfectly fine however, and there are no other nasty side effects.

runs 3.1 roms, CF card boot and dvdrom, all work fine with an Apollo 030 +16mb ram.

This will be some fault with the Sony video encoder that converts RGB to Composite. The RF modulator is fed from the Composite signal also. The RGB output on the Monitor port comes straight from the AD101 Video DAC so it won't be affected.

I wouldn't worry about it unless you need the composite output

Excellent! thats good to hear.. I have a scart cable.. so it won`t be effected

Not so good actually.. I have a green hue on comp, rf and with my rgb - scart adaptor..

whats the deal there then >?

Hmmm have you tried RGB to 9pin monitor?

thats what imma running here my friend.

Have you checked all the pins on the connector on the back of the Amiga to make sure there are no bent pins or pins pushed in?

stainy · 01 November 2006, 22:19

Yeah but I`m geting green on ALL outputs.. only pins on the RGB and they are all present.

I don`t have a monitor/cable to try... so not tried that as yet

ok I guess you checked the greenscreen buttom on the monitor

I once had a simular problem on my 500 and it was due to a faulty ramexspansion. You might need to open the amiga and try pushing down all the chips, if remember correctly some of the chip might popup a little.

tried reseating the chips..I`m not using a monitor, I`m using a tv.
Tried with scart input and composite also...
