Re: my DR-B300ATX power supply is failing.
Dont try to repair your Power suply unless you know what your doing. They can hold enough charge in its capacitors to electrocute you.
Just remove it from P.C. take it to a computer store and say: Eh hem, I need one of these to replace this one.
Make sure its got at least the same amount if not more connectors as the original, make sure its also the right type I.E. ATX POWER SUPPLY, and I would recomend getting one a little stronger than the one you blew out, something like a 350w

Your original problem of failed electrolytic capacitors (common) may be the same one occurring in the replacement if it was a 'pull' from another set.
Normally, depending on the quality of the parts used, these supplies will survive for several years before failing.
If this was in fact removed from another set, it's time to return it if there was any kind of warranty.
If not, the repair cost isn't that great if you have an honest tech in your area.
error39 is a cd/dvd issue im not sure if this will help Fist clean your computer of
dust using a fine air blower from a compressor specifically around your CPU
central processing unit making sure there is no moisture in the air line dust will cause a lot of
static which will make a computer overheat and cause lots of unforeseen
problems Test your power supply unit
if the PSU units fans not working its faulty
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect your hard drive boot up
Test all leads that attach to your hard drive including
the leads from your ((motherboard to your hard drive)) make
sure they have a secure connection and are not faulty or just replace them they
could be faulty make sure all leads that
are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections
and are not faulty or just replace them they could be faulty ? one bad lead will end with
a computer error computer error a computer needs its connections continue its cycle and have an
end to function hope this helps
I recommend you replace the switch mode power supply. These power supplies have dangerous mains voltage inside the unit and you should not try to repair if you do not have electronic knowledge. The cost of a 500 W ATX power supply should be approx. $100. It is not difficult to swap out the power supply, make sure you have the power connectors are the same as the old power supply.
Few reason for the shut down
Could be heat, electrical,
1. try cleaning all vents with compress air in order to remore dust and fuzz that can be cloging the vents.
Once this done, verify that fans works proprelly,(check air flow coming out of vents) if they dont they will need to be replace or cleaned out.
2. Check power supply unit, and battery.
Sometime power supply unit is defective, getting too hot and power output is not stable and shuts down the laptop. ( change power supply unit) check if battery hold charge. if not change battery
3. Check connections for looseness and contact
If all seems normal,and none of the mentionned point seem to be defective, the cause is deeper and would need to be looked at by a technician.
I assume you are talking of the 20 or 24 pin connector plugging into the Motherboard. Is it 20 or 24? Is there a 4 pin +12v connector plug. The colors of the wires tell a story. Red is +5V Black is Ground or Return. There is Yellow and Orange and Blue and green and gray. There are SATA connections . Look in your users manual of a standard Motherboard. This will give you a pinout and voltages on these pins. Write down the voltage starting with pin 1 and add the color to simplify knowing the voltages. If you're tech savvy, break out a multimeter for absolute certainty.
It seems a lot of people are having problems with the Protron power supply. I’ve been able to repair all the ones I’ve seen so I’m confident I can fix them. I don’t sell the replacement power supply but I’ve heard about the ones on EBay. They seem to be a mishmash of two power supplies (12vdc and 24vdc) wired together with the proper connector. This should work but it just doesn’t sound very clean looking to me and they end up costing $150. I’ve been charging between $50 and $100 to repair these power supplies. My recommendation would be to send me the power supply I’ll check it out and unless it’s unusually damaged it will cost $50 plus shipping to repair. If I can’t repair it I’ll return ship it and only charge for shipping. I will guarantee the repair for 1 month. I don’t know what’s causing the power supplies to fail so I can’t guarantee it any longer than that. My feeling about the reason the Protron power supply stops working is two part; could be overheating due to lack of proper ventilation to the power supply; or the TVs power requirement is overdriving the power supply. Feel free to contact me if you have any questions. I repair these at my work, so here’s the shipping address: Dave Simpson 23372 South Pointe Dr. Ste. B Laguna Hills, CA 92653 Also, I’m set up for PayPal. email@example.com
