Hi guys, sorry for not been in touch for so long, I have been very busy with work, and thanks very much for all the advice and time you have spent to help me out. I found the information very useful and I am definitively a leap ahead since the initial post, however the different opinions I received did put me off a bit since I was hoping for a simple streight answer.
of course this is not possible as it is many people answers.
I could attempt to clean up the board and improve the overall soldering, a heat gun does not seems very expencive, around £15 on ebay, but what would be the specific model type I need for this job?
I can also disconnect the heatsynk to prevent any possible shorcut and hope that, no furter damage has been caused to the transistors.
but the problem really is how to test the little square bit to makes sure is working before I try to put it back, or maybe I shall just replace it as the cost probably will be negligibile.
Because there does not seems to be a clear agreement on what it is maybe a good idea would be to just send it off to some specialised company to find out and provide a replacement, anyone knows who deal with this kind of components? the link posted does not work.
Another issue is the capacitor, some of you says it might not be needed at all, then why it was there in the first place, is it possible that it was just put there as a joke? I dont know. This is confusing because I thought every component is necessary and nothing will work without it. So shall I just try without capacitor? or shall I just solder any capacitor to see if it gets better? I am not too sure what I am doing, and as I understand there are quite a bit of different capacitors to try out it really makes me wonder. The remainings of the exsisting one does not shows capacity and voltage so I am stuck with this one...

Wow It looks like the parts were placed on the board with solder paste, and then never heated. Or not heated nearly enough. Anyway this means that no one even took a good look at the board befor they shipped it. This a clear case of defective workmanship. Makes me wonder if it could have possibally passed test.
Full refund is in order.

Yeah, but the guy is not availabile on the phone or emails, I have tried for months, and no one answer. If I have to re heat the board, is there some kind of solvent or liquid that should be spread on the board itself before heating? I have seen a video on you tube and it seems you should first put this liquid on the componenets and boards before heating them up. anyone know what it is?
