Re: TPC8109 transistor problem ? - Help please

Good to see you in this neighbourhood again, Nick... :thumbs-UP: Hope all is well by you. Rest assured that TPF hasn't forgotten you. Hi George, and great to be back here again. Also to you Dominic and thinking of the trans Atlantic work we did together. Greetings to you both and everyone else.

Re: Upper usb port NOT talking with me....

Woah a minute....! Is the USB port physically damaged. If so it needs replacing and RBS's method is correct. BUT, if there's no visible damage, it's likely to be an unsoldered Southbridge chip. it's one of the more common faults to see one USB working and not the other. Reballing the chip is the sol...

Re: fan error woes

First of all what "Fan Error" were/are you getting? The fact you've got another fan could be irrelevant, as the temperature the fan switches on at is controlled by the motherboard circuitry, not the fan itself. If the fan appears to run at full speed when first turning on, then it's likely to be wor...

Now I think about it, it was a bit of a stupid question since if the CD Drive works then Ultrabay HDD's should as well!

T43 SATA Convertion - Do PATA drives still work in Ultrabay?

If a T43 has the SATA convertion, will any PATA HDD's fitted in an Ultrabay still work considering the SATA /IDE chip will have been removed?

Thanks in advance.

Re: T43's CPU maxing out on basic tasks and freezing

Yes, it sounds like typical unsoldered Southbridge, which is sorted out by infrared reballing and I've done literally hundreds of these on T4x's.

Give me a shout via PM or via my website link - not too expensive either!

If you're first name is Ian, I've just replied to you. if it's not then get back to me anyway and I see what we can do.

I've also suggested that you think about having us carry out the SATA mod at the same time as in RBS's post.

Good luck and I hope we can help you.

Re: Missing GPU aluminium shield

FTC has a good point, but there is a problem using just one copper plate. Some (and maybe all) original Aluminium GPU heatsinks have a raised section to contact the actual square GPU part of the chip, with the rest of the heatsink contacting the slightly higher VRAM chips (if you see what I mean!). ...

Re: Experimenting with a flaky T42

Since you're wanting to do a DIY reflow job, you'll need to remove any red, black or orange dots around the chip (there may be none). Remove them by gently heating (a temperature of a lot less than solder melting point is needed) the chip until you can flick them off. The reason for doing this is th...

Whilst this is good in theory, in prac...
