Mclaneinc #1 Posted October 15, 2020 (edited) 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...

flashjazzcat #2 Posted October 15, 2020 Dead CPU or bad RAM are common causes. 1 Quote Share this post Link to post Share on other sites
+Nezgar #3 Posted October 15, 2020 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. 1 Quote Share this post Link to post Share on other sites
flashjazzcat #4 Posted October 15, 2020 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. Quote Share this post Link to post Share on other sites
Mclaneinc #5 Posted October 16, 2020 Thanks people, I'll take a trip to his place on the weekend with my syscheck and see where we go..Thankfully he's in East London, I'm West London.. Quote Share this post Link to post Share on other sites
