Hi,
My Amiga has a harware trouble.
its spesifications;
* A500 with TV modulator. (revison 6)
* 1.3 ROM
* 512K CHIP + 512K on-board FAST RAM.
* Standard custom chips.
Here is symptoms;
* Screen is always black
* Power led flashes
Its history;
* 7 months ago, I installed four RAM Chip (44c256) on its board.
* I put 4 330nF capacitors for each RAM chip. (but they were
little bit taller than the originals)
* Last week my Amiga did some nonsense things;
It didn't read my good disk, give r/w error or
not a DOS disk. I though it caugth a virus.
But when I re-boot it, the 'put WB disk' screen
appears later on and its colors were disorder.
I opened-up its cover and I saw the capacitors
which I installed has been broken by the pressure
of the metal cover of Amiga.
I pulled-up these four capacitors.
* Then, it worked agaiiin.
But it had worked well just for 1 week, last night my Amiga
is dead as I described above.
I think its RAM or ROM is burned. Did you ever meet these
symptoms before ? What's your idea ? What can I do ?
Please help me ! Every suggestion will be appreciated.
help!
