Hi folks,
I am a bit worried bout my good ol' amiga 500.
This weekend, I wanted play some old stuff on my amiga.
So built up to whole set and started the amiga.
By switching on, the screen lit once, for a very short time and got black again. Pressing the caps key, I can recognize that power must be in the machine.
I turned it off and meassured the power supply. Everything seems ok?
What's wrong with da amiga? Are the kick roms outta order?
Please help me.
Thanx and best regards,
Da Harry

If the kicks were shot, you would probs get a red screen....
is the power led on?
is it 500 / 500+ (maybe batt probs)
has it got a mem board upgrade??
can ya be a bit more specific?
-
HI ,mine was half dead until i find out wats the problem , in my case chip for floppy was dead and that coused my amiga not to work. I bought the chip from local service and all problems were done. Maybe its problem with the power? :-(
-
are you sure the monitor/television in ok!?!? :-)
-
Dust inside the machine? Twice my A1200 refused to boot up properly (going scarily mad with the hard drive the 2nd time round- whirring in dagerous ways), but a small vacuum cleaner (like one of those portable ones) might do the trick. You'd have to open the amiga first (But-oh no!- that would void your warranty :-D ).
Another time it was the monitor. Check by connecting your Amiga to something else, if possible.

@daharry2003:
Because of time, heat and vibrations the socketed chips in the A500 will try to move out of their sockets a bit. A good idea would be to open the machine and press all the socketed chips firmly into place. This fixed my A2000 when it didnt function.

If pushing down the chips doesn't work, sometimes pulling them out and reinstalling them does the trick.
-
If all else fails then try washing the motherboard in warm, soapy water and drying it over an open fire...
then look on ebay and see if Redrumloa has any refurbished A500's left...
;-)

Well, first of all, I want to express my big surprise due to the overwhelming many threads posted in only one night...
1. I connect my amiga usually to my tv.
2. Nothing but the caps key led is shining or flashing. No power led on or disk drive led.
Still some ideas?
Thany a'lot.
-
Hmm... does the disk drive kick in if you cold boot it with a floppy in?
I doubt its the kickstart causing that.
Is it an a500+?

@daharry2003:
How many times is the caps-key flashing?
Check out this Amiga Selftest Page (http://amiga.emugaming.com/selftest.html) to see what the keyboard is telling you.

Throw away! Throw away!
Bunch 'a rust
throw it away
before it turns into dust
before it turns your room into decay
Buy a new one, there are still enough on sites like Ebay

ummmmmmmm, try getting a voltmeter, try it on the the power and disk drive led's, also, instead of using a vacuum cleaner, get one of those static-free , water-free, everything-free :-) air-in-a-can from computer stores, and then blow around the keyboard area including where you can under chips etc...
The keyboard also has its own processor, RAM, and ROM. It also has a selftest that performed on power up in the following sequence.
Performs a checksum on the ROM.
Checks the 64 bytes of keyboard RAM.
The timer is being tested
Performs a handshake with the computer and gives the result of the selftest.
If the keyboard does not pass the test, it will tell you through the blinking of the caps lock light.
One blink: Keyboard ROM check failed.
Two blinks: Keyboard RAM check failed.
Three blinks: Watch dog timer failure.
Four blinks: A short between two lines or the special control keys.
READ THIS (please). Don't panic if your keyboard flashes once when you switch on. THIS IS PERFECTLY NORMAL. Every Amiga in the entire universe does this.
check all that out :-D and give us more info
-
Checking out.
So. None of the leds are neither lightning nor flashing. Except the caps key. It lights once when switching power on.
Hum?
Well?

To daharry2003:
I can sell you a new Amiga 500+ mother board for only $15.00 plus s/h. Let me know if you want it. It is inside a sealed silver anti-static bag and is well protected. I also have a new Amiga 500 keyboard for only $12.00 plus s/h. I also have vintage Amiga 500 games for only $2.50 each. :-D
-
Or you can go on ebay and get one for like 10 dollars or something :-P
-
lol, exactly, just go on ebay and look for something that has been run over by a truck, but in uch a way that the keyboard is intact, so it only costs $4 :-)
-
a500's are so common and cheap, im guessing that if you get a 2nd hand one, you will be able to at least make 1 working one... Or maybe get yourself an a1200 with HDD, Accelerator, Memory upgrade, etc.etc.... :-)
-
I'll tell you what Commodore told our service guys when we a dodgy A500 came in for warranty, disconnect all cables, lift the A500 30cms in the air and drop it(preferably on carpet), worked then, worked for me when I pulled my A500 out the cupboard, and I'll bet it will work for you.
PS. Don't blame me if you kill it once and for all, I am only passing on an old trade secret.
BTW Welcome to a.org

If its an A500+ have you checked the battery?
My A500+ wouldnt boot recently and when I looked at the battery it had started to leak and one end had gone "fuzzy". I cleaned the "fuzzy" off and away it went. Later I replaced the battery.

"No worries, I'm fix him" ;-) No, seriously, that was Commodores "fix", I kid you not.

WRONG!!!! The Amiga 500 stuff on eBay are NOT NEW! The Amiga 500 motherboard and keyboard that I am selling are brand new. :-D

Why would he want to get another low-quality piece of crap like the Amiga 1200? It would be much better if he bought himself from eBay an Amiga 2500, 3000, or 4000 computer. Then he would have something to be proud of and brag about. :roll:

Yup still have some left fromt he inventory reduction sale.

@Redrumloa
That reminds me, the CIA works great, the A500 now boots up fine.
