a4000 red screen + more
I was playing with my a4000 last night and It started to act odd...
while playing games it started to stutter. I loaded up workbench and it came up with an odd message like "cannot read rom....(something)" then it had a red screen on the boot up but after a reset it loaded ok......now all I get is a black screen I have taken out all of the extras in the a4000 and taken out the roms and put them back in again....but it still refuses to work??? any ideas??? |

red screen is typically some hardware or memory failure :/

thanks for the quick replys!
Yeah i was thinking the problem was something to do with the roms....either that or I did not do a good battery leak cleanup looks like I will have to splash out on some new roms. this a4000 is a pain in the arse to keep working |

Have you held down both mouse buttons? (this probably won't reveal anything either unless you have a 15mhz display) Disconnected your harddrive(s) to see if a workbench screen appears? Depending on your monitor (graphics card) you may need to connect rgb into an appropriate 15mhz video display... i.e. if it does boot even momentarily it might be breaking before reaching the 31mhz or what not display mode so it stops/crashes on a black screen...
I've had many interruptions with the A4000s I use and none of them has resulted in actual hardware failure/replacement... Be maticulous and take your time... and... good luck... otherwise how much you want to sell it for and I'll fix it myself *wiggle* |

My A120 works like a dream My A600 works perfectly (no DD tho) My SX-64 runs great (after we changed its PLA) My C128, which I have used for many, many years, sill works fine after we gave it a brain transplant (new ROMs) So I supose it depends on the machine. My iBook has 2 years and its screen cable got fucked and needs repair. 2 bloody years! |

my Apple Macintosh Classic II is quite more complicated than an A4000 and even has a battery that leaks, nevertheless it still works superbly and when it locks up, the good ole "jam in the side" fixes it |

Well, although the red screen means that the ROM checksum was calculated wrong, it does not necessarily mean that the ROMs are bad. Because if the ROMs were damaged, there would be nobody to calculate the checksum. If the Amiga shows a red screen this basically means that the processor and the ROMs are still there but there is a problem with calculating the checksum. This might be due to a damaged ROM, but it might as well be a damage on the motherboard, in the pocessor or bad RAM or a too weak power supply. And of course a leaking battery may cause damage to the motherboard which leads to a red screen.
