Introduction - New Amiga owner

[ramis77]

Hi!!
 
My name is Ramiro Aranda, and I have an Amiga 500 just from yesterday. I am spanish and have 32 years old. I´m not a programmer, but I like video games since I was a child (I had a 16Kb RAM Spectrum). Unfortunately, I have never used an Amiga.
 
I have no idea in how to deal with the Commodore, so I expect to learn a lot in these forums.
 
The computer came with a big joystick and more than 200 disks, and I don´t know yet how much memory has installed.
 
I tried to turn it on last night but my old TV didn´t work, and I could see only the screen in one colour in my plasma TV (with Amiga 520 connected), I suppose I have to get another old-tube TV.
 
Moreover, the computer has an interruptor near the disk driver, and I have no idea of what activates...
 
I think I will have to read a lot here!!
 
Regards,
 
Ramiro

Thank you for your repplies!
 
The colour is green. Is it easy to repair?
 
And what about the switch in the right side of the computer? It seems to have been added making a hole in the case...
 
to ferix: nice to meet you, I live in Zaragoza.

I have opened the Amiga and:
 
 - You are right, there is a 512 Kb expansion card. At the internal side of the switch there are 2 cables that are solded to the expansion card (they are OK) and 3 cables that go towards the Amiga mainboard (2 of them are desolded from the switch)
 
 - I can see corrosion in the battery
 
I am going to ask for a solder to fix the cables but I think the computer is going to work only without the expansion... Is it easy to get and replace that battery or maybe I should look for a new expansion card?

[ramis77]

Bad luck,
 
I have removed the expansion card and I have the same green screen when I try to boot. I don´t know if I have to do something with the three cables that went from motherboard to the switch (I have tested to unit between them but the result is the same)
 
Do you think is worth sending to somewhere to repair it?

[ramis77]

Thank you very much for your help!
 
Although today I am very dissapointed, I will do my best to repair it!
 
I´m going to start inmediately to follow your instructions.
 
I promise to report it!

It is a blank green screen. I have just realized that at first it is orange but turns into green in less than a second...

[ramis77]

I extracted Denise, Paula, Gary, Odd CIA A & B, and 68000. It doesn´t work yet. Waiting for the special tool to extract Agnus...

[ramis77]

thank you all for your replies!
I am going to work, but this afternoon will check the temperature on chips and will take some pics.

I have checked the chips whith the computer turned on and:
DENISE, PAULA, GARY, 68000 and AGNUS heat up, but I think memory chips do not.
I enclose 3 pics:
1) Amiga board general view

2) Expansion wires joint to board

I tried to join the ends of these three wires between them and it all was the same.
 
3) Expansion card

Before turning green, the screen is sometimes orange, sometimes pink for less than a second!!
 
I have a voltmeter, could it help? Any idea?
 
Saludos,
 
Ramiro
