Good Morning All,
I've recently dug out the Atari XE/XEGS whatever you want to call it from storage hooked it up to find I've got no video from any of the output options.
I sometimes get just a blank screen then other times I get a brownish screen, most times I get what looks like v-hold failure with a single white bar except its diagonal & rolling no amount of tweaking the v-hold changes anything also I've got no sound.
The guy I bought it from was trying to hook it up & not having any luck but figured it was just him not knowing how to hook it into his modern flat screen. I bought it untested from the counter of a RadioShack after he got frustrated by the clerks trying to sell him $30 worth of adapters so I've never actually seen it working myself.
Things I've tried:
1: Multiple screens/outputs/cables.
2: Tested power supply voltages which were accurate.
3: Cart/No Cart inserted.
4: Booting into the self test.
5: Checking for hot chips on the mainboard none are particularly concerning. I can thermal image the entire board later.
6: Just hoping it was waking up from a long slumber.
I'd appreciate any ideas as troubleshooting this beast doesn't seem to be covered all that well anywhere nor does a FSM appear to exist. Where would I buy any spares for this machine as I understand some of these parts are exclusive to the XE/XEGS.
Thanks
