At my request, I give the following information: your Gertename: Star Trek (proto) Technical Documents: I have the complete documents. My knowledge: I can read and understand circuit diagrams. HowTo: I've informed me. Existing measuring devices: digital multimeter oscilloscope. Ltkenntnisse: Ltstation and knowledge available. As the error has occurred: Even when the previous owner. An identical in terms of boards Flipper: goodmans gfsat101sd I own. Error Description: hello there ... I am currently goodmans gfsat101sd on the complete revision of a "Star Trek" and now I have a problem that I simply overburdened. I was able to narrow down the source of errors on the MPU, merely I do not know what it knnte lie. Problems: 1) MPU boots first error-free, re-boot but again after a few seconds. - The time interval is NOT constant! - Self test is allowed to start, goodmans gfsat101sd however, there is no later than after the sound test, a reboot! 2) All controlled lights "flicker" slightly Ausgefhrte work / test setup - Smtliche Molex connector in the Gert are new bestckt (crimped) - Power Supply is completely revised (rectifier, Fuseholder etc.) - Solenoid Driver Board Revised (C23 & C26 new) - cleaned MPU, replaced Sttzbatterie. - Only connect power to SDS / MPU. (No matter what other components are connected, the error is always the same) When installing another MPU (Supersonic) air this error and the flickering is gone. The use of any other ST components in Supersonic, where it causes NO problems. So I'm 99% sure that there are on the MPU must. Thank you for your tips and suggestions.

Then I dignity times remeasure the 5V voltage with multimeter and oscilloscope. MPUs behave goodmans gfsat101sd at too low or poorly screened 5V voltage is not always the same. Another solution wre via an external PC power supply 5V to feed, to see how responsive the board. I dignity the 5v directly to the components measure once, not something on the MPU pulls down the 5v.

I dignity the 5v directly to the components measure once, not something on the MPU pulls down the 5v. Michael Have I done so - as far as all voltages and tolerance! The TP's and various 3.3V, 2.4V, 2.6V 0.4V, etc. The fact that it must be due to the PCB itself is now definitely - built-in Supersonic makes this nmlich the exact same error. Other observations: - interval between reboots varies greatly (attract mode). Between now up to 1 min or longer. Start of Self Test lst the reboot usually goodmans gfsat101sd very quickly - Drcken, Tapping, Tapping goodmans gfsat101sd on PCB / IC 's no lst (zustzlichen) Reboot from - Self Test switch over test also happens to be gone. No extreme values (01-11) credits (05) is displayed correctly. - No Vernderung goodmans gfsat101sd by Nachlten smtlicher socketed IC's - The flickering of the Lamps is identical goodmans gfsat101sd in Attract mode and the lamp test - No effect when using KLTE (spray). (Geschtzte frequency 20-40 Hz) __________________ FOREVER PINBALL - Even in Switzerland! Flipper Freaks Wanted - Revival erwnscht!
Today I also smtliche socketed IC's goodmans gfsat101sd replaced: U9, U10, U11, U7, U8, U14. (Without ROM's, since no replacement available). Sorry, no Vernderung goodmans gfsat101sd the problem. It flickers and reboots continue ... :-( __________________ FOREVER PINBALL -! Also in Switzerland wanted pinball freaks - Revival erwnscht!
Now I have changed even smtliche ROM's, which has also brought no Vernderung. Unfortunately, goodmans gfsat101sd there seems to be no solution for this problem to give and I'll install goodmans gfsat101sd an Ultimate MPU. So if no one has an idea, this thread can probably be closed as ungelst, respectively. be deleted. Anyway, thank you for your intrested and Tips C-Fox __________________ FOREVER goodmans gfsat101sd PINBALL - Even in Switzerland! Flipper Freaks Wanted - Revival erwnscht!

Well, I have not exchanged honestly, merely all nachgeltet and controlled. I always try not unntg to "torment" these PCB's and especially their Ltaugen ...
