Re: When to know a board is dead
well there are a few chips that i've been told are FET that the solder joins seem burned and these are directly linked to the power circuit? the board shows power light and battery light constantly on even without battery, and when battery is inserted it flashes to show charging but its actually not.
hmmm interesting stuff, dont actually think the board is completly dead so off to get the chips out and replaced i guess, but how do i find out whats causing them to fail, can i run any kind of test to ensure once replaced they wont die...Leave a comment:

When to know a board is dead
as you might have seen my many threads about my laptop, well heres another
im just wondering how do you know when a board is completly dead, like no way back for it at all as i've been reading a few post of boards about ppls problems with thier laptops and the fact that their power circuits have died.
once that circuit dies it is dead forever? -
Re: PCB board repair - anybody ever tried/done it?
Ok, but im really wanting to find out the tools i'll need first - will a multimeter do the job of testing?
also if i find a bad chip, how in the world will i know what made it go boom?!
confusing but im getting there, so bear with a lil
also what kind of tips will i use and what kind of solder sucker would it be?
stupid questions i know but its a startLeave a comment:

Re: PCB board repair - anybody ever tried/done it?
thats great news thanks
what kind of tip should i use for the solder would my 30w iron be OK?
i've searched for some tips on ebay and havent found any that look up for the job, is there a part name for them?
thanks a bunch guys this is helping so muchLeave a comment:

Re: PCB board repair - anybody ever tried/done it?
i see so those chips in the pics i gave are DIPs? im just waiting on a de solder tool and i'll see what i can do
doesnt matter if i mess up really the board is probably dead so its a practice board either way
hmmm what tool to remove the chips a dip extractor?Leave a comment:

Re: PCB board repair - anybody ever tried/done it?
thanks for the advice thus far im learning a great deal.
what would i use to get the chips out could i just yank them with a tool such as a dip extractor? or would i need to desolder them?
and are those in the photos actually soldered in, they look very flimsly?Leave a comment:

Re: mutiple videos on dvd
well thats ok for converting dvds i know how to do that one already, i used to use TMpeg
but what would i do with avi files, lets say i wanted to write 3 movies to a dvd but also have a menu to access them?
or could i just put them all onto a dvd and it would auto sense them from my dvd player?
and.............if i put them on as data would my dvd player pick this up?
thanks for the help
loving this forum!Leave a comment:

mutiple videos on dvd
im wanting to put a few movies onto a disk, i've seen some non legit dvds with menus and up to 4 movies on at a time!
how would i do this, what would i search for, or which software to use?
thanks -
Re: Hard disk problem
yeh it was a bad drive, just playing around with it
and yes one of the other drives was an ibm! now that i hadnt touched its just developed a "death rattle" and forever clicks althought it works very slowly
and i just ordered another ibm too
time to cancel the order!Leave a comment:

Re: Hard disk problem
well i took it apart as its an old drive i just wanted to play around with, just wondered why it was dead, didnt know that by taking it apart you had to be in a clean room
but it was fun checking it out
what about the pcb thats attached to the disk, would taking that off also kill the disc?Leave a comment:

Hard disk problem
i have two harddisks and i have a problem where the disk is just making a clicking noise, one drive i know may be damaged mechanically but the other i think is OK
what could the problem be?
i've taken the hood off one and watched it go and the arm just moves back and forth constantly clicking
sorry its not much of a description
in the bios it picks up the drive correctly
so whats the dealio yo?! -
Re: PCB board repair - anybody ever tried/done it?
im just worried this board wont allow me to renew any of the chips as its covered with some sort of membrame i think, the traces are underneath if you understand what i mean
if it is possible, would i need to desolder the chips then extract?
but what kind of tool do i use to extract them with? i've searched on ebay and the closest i've found is [url]http://cgi.ebay.co.uk/8-28-Pin-Dip-IC-Extractor_W0QQitemZ7568219238QQcategoryZ73154QQssPageNameZWD2VQQrdZ1QQcmdZViewItem[/url]
will this be the right...Leave a comment:

Re: PCB board repair - anybody ever tried/done it?
is it possible i could replace them? the board seems to have a membrame will it be possible to remove the chips and replace them easily?
what kind of extractor tool should i use
where would i get the replacment chip
what sort of solder technique should i use?
and finally what sort of solder equipment i have a 30w iron will that be ok?
and i have 100g solder - is that ok to use?
also a good guide to soldering
many thanksLeave a comment:

Re: PCB board repair - anybody ever tried/done it?
dont know if you can tell, but there looks like burn marks on one of those chips.. what are thier jobs, what do they control/regulate?...Last edited by enigmatic; 05-28-2006, 07:01 AM.Leave a comment:

Re: PCB board repair - anybody ever tried/done it?
yeah i agree about visual learning, some people are best attainted to doing it that way.
i'll take some pictures in awhile but what do i aim to take?
i've noticed a few components a little black on the solder joint, i'll take a pic of that but i cant really see what else there is to take
if i take a close up of the whole board in high resoloution where can i host it?
imageshack accept high res pics?
thanks once again maybe it can be resurrected, if not i'll...Leave a comment:

PCB board repair - anybody ever tried/done it?
I've been reading around [url]http://www.circuittechctr.com[/url]
found it most interesting about what types of repair you can do to circuits but im looking for more information my board is a sony vaio i believe its double sided, not quite sure i get baffled and lost at this point but knowledge is power!
anybody know of any techniques to test, repair, look for faults?
what tools could i use to show me a diagnostic report (perhaps of the bad circuits)
and what would i look for that would need replacing?
any info would... -
Re: Diagnostic report cards (pci, usb)
hmmmm so does that mean it will tell me if there is something wrong with the power line on the board?
i've noticed there are some out there that offer a lot more indepth soloutions such as a GUI for all sorts of diagnostic test but they are purely $1200+Leave a comment:

Re: Diagnostic report cards (pci, usb)
so it wont tell me anything about the power functions of the board? i have seen most of it to do with the bios etc, but will it go outside of that a lilLeave a comment:
