Right
I currently own a Spare Sony Vaio VGC VA1 , Desktop Alli-inOne , the computer must be 5+ years old and the PSU is on it's way out . The PSU is making horrible buzzing sounds , unfortunately these PSU's are Very, Very, Very difficult to get .Not only that, but the PSU has an odd 18 pin Motherboard connector . This dreaded, Supplied PSU is a Delta Electronics DPS 290 AB ( is it 295w ?) , Here's a picture of the PSU , I managed to dismantle the whole Machine , no easy task , about 30 odd screws and a bleeding cut later ....
Well after I searched for hour's and hours on ebay and the net ,I then spent £20+ talking to Vaio's rubbish Tech support, to try and source a replacement , but to no avail .I had to settle for the most similar PSU I could find . It is however almost identical in dimensions (wxhxl) . It's around the same power , perhaps a bit less (250W?). This replacement PSU has a 20 Pin motherboard Pin , unlike the original 18 pin connector . Here's a picture of the label on it for reference:
As the original Delta Electronics PSU's have a tendency to burn out , I gave up on the idea of a replacement , I have read from many ex -Sony owners about these all in one PSU's . If we can find a suitable replacement method using a splicing method from a standard PSU , it would save a lot of money and landfill space . I read this article from another Sony Vaio All-in-One (VGC-M1) owner , He managed to replace the original 18 pin Power supply known as the DPS-197AB , the same as mine , just less power , also discontinued and very, very, very difficult to get .
I havent been able to get in touch with the author of this post , though read the article here http://www.bearware.co.uk/2011/02/03/sony-vgc-m1-psu-fix/
So after reading the article , I assumed it would be a case of just matching up colours and splicing up a new PSU . All of the colours of the new PSU seemed to match up and wasn't difficult to do , apart form a blue wire and brown wire I left disconnected (as shown) . I then plugged in the new spliced 18 pin connector . I cant see why this shouldn't work , can you ?
Splicing
I then connected up the 4 Pin CPU using a molex to 4 Pin cpu converter connector. Seems the converter connector cable uses two 12 v wires, doubled up onto one pin
I then spliced up the odd 4 pin monitor connector ( I think) using a single 12 v (yellow wire ), as I run out, and ground wires. Again just simply matching the colours up . This should work in theory right??
I also used a Molex to Sata converter to connect the HDD, As the new PSU doesn't feature Sata connectors, see here
So thus far , everything is connected up , despite the spare brown wire ( form the old 18 pin connector) and the blue wire ( from the new PSU) . In theory everything should work in relation to what I read in the article link http://www.bearware.co.uk/2011/02/03/sony-vgc-m1-psu-fix/ However I did plug in the PSU and tried to boot up and just silence , nothing happened , no boot at all. Here's a picture of the everything wired up
So what should I try next ? I have already threw £25 at a new PSU , £20 talking to Vaio Support (£1 per minute)
, hours and hours looking for a new PSU and Hours dismantling the awkward case
It would seem to be a simple task , anyone care to comment on what's wrong here ? I guess it could be the new PSU , I brought it on Ebay , sold as working . However maybe the New PSU is faulty or underpowered , I am unsure
Seems a shame if I cant get a new PSU , although the computer is old , it still has a powerful, dual CPU, 2 GB ram , Outstanding sound and currently runs Windows 7 . If we can get it to work with a new PSU , it would be great to show others, as mentioned earlier this is a common problem that seems to be un-rectified . Sony doesn't care less and I can only assume most people would just dispose of their faulty machines
For anyone who can shed any light , thanks in advance
