my 60 broken down again

That's cool.But i can't do that.My cash is extremely limited.

Make sure you reconnect all ribbon cables, and possibly replace the fuses. Sometimes fuses don;t break right and just create resistance, and they are cheap. You're repair guy seems cool, so I think once you figure out what the issue is you should be fine. I still think it's the power pin on the connector, the resoldering of it is good but he needs to check continuity. on mine when I checked continuity it would have it if I pushed on the pin, but if i just touched it with the probe, it wouldn't, so i had to resolder it so it would conduct well, which was just a quick touch up. it is something simple causing your grief, and if you sell it you will have problems since it has problems, you'll either get very little money or have one pissed buyer. Work out the issue, It may take time, but you can work it out.

Yes i know , it's a little thing that causes the trouble.But as long as the problem comes and goes my tech can't fix it .Maybe time will tell .
And of course i won't play a scam to no buyer.

Thank's again for all your help.
