Hi, I was into amigas some years ago and I remember I tried to join Amibay with no success. Don't remember why.
Now that I easily register, I would like to ask a question about a A4000T that I am going to sell.
Long story short, about 4 years ago I bought the motherboard and every single piece that I should solder them on my own.
I soldered only the items needed to get into the insert disk screen. My problem was that I had no permanent problem. One day through diagrom I could see the screen and the other day without doing anything I had a black screen.
My question is, is it better for me to sell it as a lot? Or sell them in single parts?
Thank you and nice to meet you.
 
A lot of things have changed with Amibay since when you tried to join. As for your question, you might be better selling separately. Please read the rules though (if not done so already) and welcome to Amibay!

Thanks for your reply. i read the rules when joined yesterday and i can't understand the thing you say about the proof? How can i proof that something is mine?
 
Ok, lets say for example your were selling an Amiga today. You would need to grab a small piece of paper and write the following and place it next to or on the item.

Welcome, I would first ask an expert repair person to take look at your board, before selling. There are enough experts on this forum that could help you with that ;-)

If it was some years ago I would be happy to find the problem and have a working A4000T. Now I have a 2 years old girl and I really have no time at all for something like this.
I have to search every single pin on every chip for bad soldering.
Thank you for your intention to help me but I think no expert from a distance can help me with that.
However I will upload a couple of photos to show the progress I had.
 
Here are some pictures.
It needs a lot of money to send it, take it back and pay the expert.
Plus, I don't want to build a 4000 anymore. It was something I wanted 5 years ago and it is over :)

Ahh this needs to be build, well I am sure someone here would like to finish it. Might be the angle of the photo, but Alice and Lisa socket don't seem to be straight it's like they are a bit ( ) warped

Everybody have told me that :) it's True it seems bent.
But I have checked almost every pin on every chip that has a good contact and has a continuity on every track to wherever they lead.
 
This one does not look too good. I'm reading this is a delay chip. If that is malfunctioning, you may be getting transient issues.

I was building the motherboard according to a german website.
I was about to solder only the parts needed to get the insert disk screen and I soldered this delay chip by mistake. I couldn't remove it so I cut it off. Even though it doesn't look beautiful, I tested for continuity on every track if the helps.
I thank every one for your help but I am not asking for advices to make it working. I don't have time anymore for that even if I wanted to 😔
 
It looks like some of the sockets are bulging? Maybe not, the issue here, but I remember having trouble with an Agnus socket that caused intermittent errors.
