Circuit Board Repair Technician needed URGENTLY

Postby wevolutions » April 25th, 2022, 11:21 am

Hello. I am looking for someone to check and repair a circuit board urgently. Most likely an IC or another component needs to be changed. Also, I need the person to do a house visit. I am in Cunupia area. More details will be given directly.

I think a Tuner does this MicroSMD or something, check the PowerSeller forum

I have been dabbling in micro-soldering for a bit. Expensive hobby because lots of equipment required, like a good microscope.

In Trinidad it's not so simple. I started doing it because my laptop conked out and I LITERALLY called every laptop repair shop in Trinidad and they don't fix motherboards (anymore). It's very labour intensive. You can't get the simple SMD components in Trinidad reliably, far less for IC chips. The only supply chain would be in bulk from China through AliExpress or DHGate, etc. Most local electronic shops like Steve's and Sham's don't really cater for this, they largely only supply the larger type larger components like electrolytic caps and resistors. They may sell some generic MOSFETs which generally won't work with the board you're fixing because most of the components on any board is proprietary. Just like the programmed IC Chips that may have burned out. The only way to replace them is to get a donor board of the exact model of another unit that was thrown away for scrap. It's rel headache which is why nobody does this anymore really in Trinidad. I called the 1-800-Dell number and they said they had a local authorized repair center on Mucurapo St. So I called them and they said they just order the entire board from their Dell supplier and replace it, nobody micro-solders any individual components because they just don't have. So if these people don't do it, nobody can or will do it locally.

If it's a very large, expensive and specialist piece of equipment, contact the authorized dealer and they will fix it through their channels by ordering an entire replacement board from the company and they will send technician can just replace the board. Or you can Google for micro-electronic repair and find a company in USA that does it and Fedex the board to them. However, depending on the component that's damaged, they may simply not be able to replace it without an exact donor board.


Sorry that's just the reality of the current situation with these types of repairs and I am telling you from experience.

all good points but i would like to add in

a good microscope is just the beginning
u need a good soldering station and in some cases a hot air reworking station

then you will need a good multi meter with precision and accuracy as well as a ESR meter to check capacitors
plus the repair component !!!

if you doing VGA chips you will need things like solder balls varying sizes and the stencils for it as well as the different types lead/ unleaded

if you have to remove a chip and do work on the chip you will need specific software that can write in hexadecimal as well as binary as well as test probes

its an expensive job as equipment alone can run into thousands 50-60KTT for starters .....
the higher you go the more equipment you need .

its unfair to say that we dont fix motherboards anymore ..... we havent even started to fix motherboards as a business as yet ....the right thing to say is no one wants to invest the capital to do it .

plus you have to understand is trinis we dealing with - want something done but dont want it at the expensive price point.

once i diagnose the board as the failure point i give the client an option - either we send it in for repair - or u can buy a new board -
and the client usually thinks that a new board is wasting time when they came simply buy a new pc ....

and so it goes !!!

I still buying equipment I have a soldering and rework station, microscope, DC bench power supply, a good JCM multimeter, ESR meter in shipping, bought a small supply of smd 1206, 805 and 603 caps and resistors that I can't find locally, every week is a new piece of something i have to buy. But it's still just a hobby because I can't source a lot of the repair components. I make my own rosin flux because get expensive now. I want a thermal camera. An established repair shop would have a lot of donor boards and are capable of ordering the chips in bulk where it would be cost-effective. Most repairs are actually simple caps or a loose joint, recovering data from a usb is usually easy enough... but the chips are a problem to replace. Some of these MOSFETS like the Vishay SIC632 I can't find it at all! The exact replacement chip and to program it, and some of them are locked like Apple chips that don't allow programming so donor board needed. It's good fun and problem solving satisfaction though. Things like the LED rear lights in the newer cars that "can't be fixed and you need to buy the whole bumper assembly in Bamboo" sometimes is just a capacitor or a generic 3-pin MOSFET.


It's discouraging to think about it as a profitable business for me, but that Micro-SMD labs guy seems to be a bit established and coming up so OP may get it fixed there. I dunno about home visit though, I not toting all this equipment anywhere from my work table.

well is now self i was coming by you ....lol..

Micro SMD he handles alot of the technical stuff for me...and i am very very happy with his repair work.
zero issues- not saying that u wont do good work too eah . :lol:

once had a dell all in one reach my repair shop. power mosfet was bad...
Micro SMD hooked me up replaced mosfet and protection diode and new CMOS battery .....
customer was extremely happy.

now hes my go to guy when it comes to hardware level stuff....


if you want stuff to repair i can give you minor jobs- things like computer speakers and small radios an stuff..
LMK !

Skylinechild where you located? I looking for.someone reliable to do computer repairs. We have endless request from customers who want their laptops and computers repaired/upgraded but the fella i use to have doing it was notoriously unreliable and would take weeks and weeks for simple things.

I located central - freeport - 10 mins from courts if ever soo much ..and you can call me sky ....(or lucy ...or lucifer....)

dont ask about the last 2 names :lol:

EDIT WRT taking weeks and weeks it does be like that sometimes - awaiting parts.
face it - i just cant go down to the wizz / wherever and get a pair of hinges or a new laptop screen / keyboard.

and yes i can get things like hard drives and memory locally......
i tend to prefer western digital and crucial ram over the brands of what we have locally....therein lies the waiting game..



see pm. 8-)
