Hi Elarach,
Ah okay, so just to recap my understanding.
1. the system did have issues with the resolution of the CRT monitor
2. you disassembled and removed the battery holding the BIOS values.
3. since then the system now fails the receive signal test during the self test and also you dont get a sector image appearing on the screen either?
I dont like publicly posting my email address. but if you go to our website (http://www.probelogic.com.au/contact-us/) and just fill out that contact form. Just put in there that you want to be connected with Ashley Barker and you are from Medwrench and then it will get directed to my desk almost straight away.
All the best,
Ash
