So, I was wondering about rebuilding some boards.

Is there a place that can do it at a decent price. Like, is there a industry already set up to do individual board repairs.

What about doing it yourself, what are the pitfalls there? I figure, the solid state stuff hardly ever goes bad. The caps, we all know goes after a time. Resistors, only when they are overloaded. Soldering is the trick to a successful rebuild, what is the process there?

I know of no company that does that routinely. Unless it's to rebuild their OWN boards, and even then, that's getting rather rare.

A local tech might do it for you. But it won't be really cheap.

You're most likely to end up doing the job yourself, which requires soldering skills and tools and a source for all the right parts,
which could be really easy or really hard.


I do rebuild some boards myself. Marquee LVPS, for example. But the LVPS has about 40 caps that really should be replaced at once, if you are going to rebuild it. The rest of them (there are 53 electrolytics in a Marquee LVPS in total if I counted right) are unlikely to fail. They're the largest ones, generally speaking.

Hello

I have not heard of any rebuilding services; PC makers want you to consider their four or five year old products obsolete so you will go buy new ones.

I have run into some techs that do reballing and resoldering and cap replacements and one guy locally that does this stuff but do you want to spend $250 to fix a $30 motherboard from 10 years ago?

I know I have a mother board that has served me well, but the caps are bulging. I installed a different MB, but I would like to rebuild that other MB as I have it all set up with correct parts. Seems silly to buy another MB and then have to buy all new cards...

I have a few cards out of my 10PG that are having issues, which I would like to fix. Fixing the cards is soon going to be the only way of keeping these CRT PJ's running. Most of the parts seem bullet proof, there seems to only be a few problems that, if addressed could keep this PJ running for decades more.

I have a bunch of old tube radios that I keep running, probably from the 1950's, even one from the 1920's.

As far as soldering, has anyone tied heating the board up slightly before soldering on it? Get it up to a hundred degrees or so.

I know he just did a re-flow on an HP touch screen desktop charged the customer $225 plus tax. He did just what you said too. Put the board in the "oven" for 20 minutes then retouched the board. Got it to post again.

RaWsHaRk: what do they charge for an 'average' repair over there.

its in south of europe, so not probably cost effective for you. I go there every summer for holiday, last time I took 3 broken laptops with me just for fun to see if they can fix them, and they fixed all of them in one week time. they charge 20 euros per laptop for reballing everything. they might fail later again , of course, especially amd chip ones...

they have a nice machine for the job that cost 2000 euros in germany. i will go there again in june, havent decided what to take with me for them to fix now, in Finland where I live i dont know commercial service that does this, just some guys who do it for hobby but it would be much more expensive and they dont have machines like that, just some companies who do work for the big guys; dell hp etc have them.

my wife is from FYROMacedonia and price of labor is a little different there...
