jham55 Posted June 16, 2022 Share Posted June 16, 2022 Hey folks just opened the 130xe for the first time. It is powering on with a black screen only. No sounds on the keyboard. The only thing I see looks like power switch adjacent capacitor but that could just be from age. Not sure where to start with this.. ordering new ram?

Sikor Posted June 16, 2022 Share Posted June 16, 2022 You try it vie Monitor or TV? Try both first. I hope you don't use Commodore PSU? If yes - probably your Atari is death Try other PSU (5V only, 1+ A), other monitor cable. Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted June 16, 2022 Share Posted June 16, 2022 @jham55 do you get an led light? If so and you are happy video cable and TV setup is OK, could be bad ram or a dead cpu. Quote Link to comment Share on other sites More sharing options...

jham55 Posted June 16, 2022 Author Share Posted June 16, 2022 I have the original PSU... I get the red light.. I tried on a CRT tv with the monitor cable and with the RF. The screen is not black with the RF.. there is color but fuzzy and no picture. Quote Link to comment Share on other sites More sharing options...
ugliestgolf Posted June 16, 2022 Share Posted June 16, 2022 Standard instructions .. start with the hot ram chips and swap them out Cpu errors I’ve seen is usually red screen not black Black could be Freddie Quote Link to comment Share on other sites More sharing options...
TGB1718 Posted June 16, 2022 Share Posted June 16, 2022 It looks like MT RAM, replace the lot with something better 1 Quote Link to comment Share on other sites More sharing options...

_The Doctor__ Posted June 17, 2022 Share Posted June 17, 2022 the monitor cable might not be correct... color without image is usually chroma without luma, does not sound like a composite cable... Quote Link to comment Share on other sites More sharing options...

Beeblebrox Posted June 17, 2022 Share Posted June 17, 2022 I've found this post on this thread below very useful in the past when replacing XL/XE ram chips. I've used Hitachi, Mostek, Samsung and Texas instruments chips from this list, sourced on ebay for relatively low cost. 4164 RAM equivalents: HM4864(A) (Hitachi) µPD4164 (NEC) M5K4164 (Mitsubishi) MK4564 (Mostek) MSM3764 (OKI) MN4164 (Matsushita) KM4164B-15 (Samsung) HYB4164 (Siemens) LH2164 (Sharp) TMM4164(A) (Toshiba) TMS4164 (Texas Instruments) MB8264(A) (Fujitsu) MT4264 (Micron) (DO NOT BUY) MHB4164 (TESLA) KR565RU5 (Russian) from here: Quote Link to comment Share on other sites More sharing options...
jham55 Posted June 17, 2022 Author Share Posted June 17, 2022 Ok here is the update after trying a few things. I cleaned a game again and got a picture that was sort of red as I jiggled the rf cable. When I switched the monitor cable for a different one I got this weird color line picture. Please see attached pics. Quote Link to comment Share on other sites More sharing options...
Peri Noid Posted June 17, 2022 Share Posted June 17, 2022 (edited) So the computer is working, at least with this cart. Does it boot to Basic screen with so connected monitor? Edited June 17, 2022 by Peri Noid Quote Link to comment Share on other sites More sharing options...
