800XL booting to yellow screen..

Recommended Posts

A mate has rang me up saying his XL boots to a yellow screen with no ready prompt, he said he was looking inside but must have touched something..

 

Anyone had a yellow screen and know the fix..

 

I aked him why he was going in to the machine and he said, "to give it a clean"...

 

Plonker...

Could also be a dead ROM... Is he close enough to you to try attaching your Sys-check on his system? (I believe you had one?) That would supplant the internal RAM and/or OS of either of those are bad.

 

Otherwise, in lieu of a sys-check or another system to swap IC's with, I could mail a replacement programmed EPROM. Probably the cheapest thing to replace first. I can also include a 2nd OS EPROM programmed with Shoestring's RAM tester to know for sure the RAM is good too, and if not narrow down the specific chip. PM if interested.

Could be any number of things; statistically it is more commonly the CPU or RAM than a bad masked ROM. There is a list of half a dozen less common possibilities we could run through (MMU, PIA, etc).

 

SysCheck is the obvious first thing to try if one is available, since it will usually eliminate a bad CPU and isolate faulty RAM/ROM. If you still see a yellow screen at that point and the board isn't socketed, the solution is then to send the machine to a technician.
